Plain petroleum jelly (petrolatum) applied under a clean bandage is the single best thing you can put on stitches for most wounds. It keeps the area moist, protects the healing tissue, and performs just as well as antibiotic ointment without the risk of allergic reactions. The reasoning behind this recommendation is more interesting than it sounds, and there are several common products people reach for that can actually slow healing or cause new problems.
Why Petroleum Jelly Is the Standard
If you search wound care advice online, you will find a confusing mix of recommendations involving antibiotic creams, hydrogen peroxide, and various home remedies. But the evidence consistently points to petroleum jelly as the workhorse. In a national survey of Mohs surgeons, who perform some of the most precise skin surgeries, about 96% reported using petroleum-based emollients for postoperative wound care.1PubMed Central. Mohs Surgeons’ Postoperative Care Practices for Secondary Intention Healing: A National Survey That is an overwhelming consensus from specialists who see wound outcomes every day.
The reason petroleum jelly works so well comes down to moisture. A moist wound environment speeds up the migration of skin cells across the wound surface, activates collagen production, supports the function of growth factors in the wound bed, and reduces pain.2PubMed Central. Moist Wound Healing with Commonly Available Dressings Compared to wounds left to dry out, moist wounds heal faster and produce less scarring.3PubMed Central. Clinical Impact Upon Wound Healing and Inflammation in Moist, Wet, and Dry Environments Petroleum jelly creates a simple occlusive barrier that traps the body’s own moisture at the wound surface without adding any active drug ingredients. It is cheap, widely available, and almost nobody is allergic to it.
For pediatric facial lacerations, the evidence is the same: early moist wound care with petrolatum promotes faster healing, while additional measures like silicone therapy and sun protection improve the eventual cosmetic appearance.4PubMed Central. Pediatric Facial Lacerations: Evidence-Based Over-the-Counter Wound Care and Scar Prevention for Clinicians and Caregivers So whether you are dealing with a child’s split chin or an adult’s surgical incision, the basic approach is the same: thin layer of petroleum jelly, clean bandage, repeat.
Antibiotic Ointments Are Overrated
Most people’s first instinct after getting stitches is to reach for a tube of triple-antibiotic ointment. It feels like the responsible thing to do. But a head-to-head comparison of a petrolatum-based skin protectant versus a combination antibiotic ointment found no differences in redness, swelling, crusting, or how quickly the skin grew back together at any time point. The antibiotic group actually had a significant increase in burning sensation during the first week, and one case of allergic contact dermatitis. The researchers concluded that antibiotics may not be necessary for satisfactory wound healing and can cause allergic reactions.5PubMed. A comparison of postprocedural wound care treatments: do antibiotic-based ointments improve outcomes?
The allergy risk with these products is worth taking seriously. Neomycin, one of the ingredients in popular triple-antibiotic ointments, is a well-known contact allergen. Reports describe patients developing widespread allergic rashes after applying neomycin-containing products to wounds.6PubMed Central. Autosensitization Triggered by Neosporin Use: A Unique Phenomenon When an allergic reaction develops around stitches, it can be mistaken for infection, leading to unnecessary antibiotic prescriptions and delayed wound care. The irony is hard to miss: the product you applied to prevent a problem creates a new one that looks like the problem you were trying to avoid.
If your doctor specifically prescribes a topical antibiotic for a wound that is at high risk for infection, follow their guidance. But for routine sutured wounds, plain petroleum jelly gets you the same healing results without the allergy gamble.
What to Avoid Putting on Stitches
Several common household products that people associate with wound care can actually damage healing tissue or slow recovery. Here is what the evidence says about the biggest offenders:
- Hydrogen peroxide: People love the fizzing action because it feels like something is happening. In animal wound studies, hydrogen peroxide applied at typical over-the-counter concentrations caused hemorrhagic lesions and pronounced inflammatory cell infiltration, with wounds showing loose, disorganized connective tissue compared to controls.7Tropical Journal of Pharmaceutical Research. Assessment of wound contraction, re-epithelialization and histological changes in full thickness excision wounds of rats treated with different concentrations of hydrogen peroxide In plain terms, it damaged the new tissue trying to form and kept the wound in a state of inflammation longer than necessary. One-time cleaning of a dirty wound before stitches is different from repeatedly pouring peroxide on a sutured wound, but repeated use on healing tissue is clearly harmful.
- Rubbing alcohol: Like peroxide, alcohol destroys bacteria but also destroys the delicate new cells at the wound margin. It causes pain, dries the wound, and strips away the moist environment that healing depends on. There is no role for rubbing alcohol on sutured wounds.
- Essential oils: Tea tree oil, lavender oil, and similar products are popular in natural health circles, but undiluted essential oils can cause chemical burns and contact dermatitis on damaged skin. Even diluted, the evidence for their use on acute sutured wounds is thin to nonexistent in humans. The pleasant smell does not compensate for the risk of irritation.
A common question is whether iodine-based products like povidone-iodine (Betadine) should be avoided the same way. The evidence here is more nuanced. A systematic review found that iodine-based antiseptics did not actually delay wound healing or cause the harmful effects long attributed to them, particularly in chronic and burn wounds.8PubMed. Benefit and harm of iodine in wound care: a systematic review That said, iodine is primarily useful for contaminated or infected wounds, not clean sutured incisions. For a standard set of stitches from a procedure done in a sterile environment, you do not need antiseptic rinses at all. Petroleum jelly and a clean dressing are enough.
Showering and Bathing With Stitches
The traditional advice to keep stitches bone-dry until removal has been seriously challenged by the evidence. A Cochrane review comparing early versus delayed postoperative bathing found no significant difference in surgical site infection rates between people who bathed early and those who waited. Infection rates were about 8.5% in the early bathing group versus about 8.8% in the delayed bathing group.9PubMed Central. Early versus delayed post‐operative bathing or showering to prevent wound complications A separate systematic review focused on surgical sites found the same: no increased incidence of infection in patients who showered or bathed before suture removal compared to those told to keep the site dry.10The Journal of Foot and Ankle Surgery. Does Postoperative Showering or Bathing of a Surgical Site Increase the Incidence of Infection? A Systematic Review of the Literature
A recent retrospective study of patients who showered early after plastic surgery procedures reported an infection rate of just 0.9% within 30 days, supporting the safety of early showering for clean surgical wounds.11PubMed Central. Safety of early postoperative showering in level-1 and level-2 surgical wounds: a retrospective study
The practical takeaway: a brief shower that lets water run over your stitches is generally fine. What you should still avoid is soaking the wound. Submerging stitches in a bathtub, swimming pool, hot tub, or lake for prolonged periods introduces both water pressure and potentially contaminated water into the wound. Brief shower exposure and prolonged submersion are different things, and most surgeons will tell you the distinction matters. Pat the area dry gently after showering, reapply your petroleum jelly, and put on a fresh bandage.
Hydrocolloid Dressings as a Modern Alternative
If you have been on social media in the past few years, you may have seen people applying hydrocolloid patches to their wounds instead of traditional gauze-and-tape setups. These dressings, originally developed for chronic wounds like pressure ulcers, have genuine advantages for acute wound care as well. A literature review found that hydrocolloid dressings can decrease healing times by roughly 40% compared to traditional wound treatments for some wound types, while also reducing pain and creating a protective waterproof barrier that allows showering.12PubMed Central. Hydrocolloid dressings in the management of acute wounds: a review of the literature
A clinical trial comparing hydrocolloid dressings to conventional dressings (the typical gauze-with-petroleum-jelly routine) after skin excision surgeries found that patients rated hydrocolloid dressings significantly higher for comfort, convenience, scar appearance, and simplicity. Nearly 97% of respondents said they would choose the hydrocolloid dressing if given a choice. Reported infections requiring antibiotics were also lower in the hydrocolloid group.13PubMed Central. Hydrocolloid dressing versus conventional wound care after dermatologic surgery Hydrocolloid patches work by absorbing wound fluid and forming a gel that maintains moisture at the wound surface, essentially doing the same job as petroleum jelly but in a self-contained adhesive format that stays put and needs less frequent changing.
One caveat: not every sutured wound is a good candidate for hydrocolloid dressings. Heavily draining wounds, infected wounds, or wounds that your surgeon wants to visually inspect daily are better served by traditional dressings you can easily remove and reapply. Ask your provider if a hydrocolloid patch makes sense for your particular situation.
Where Your Stitches Are Matters
The same wound care principles apply everywhere on the body, but some locations create unique challenges. Facial wounds deserve special mention because the face moves constantly. Research on facial trauma repair notes that sutures placed along the skin’s natural tension lines experience less stress during expressions and movement, reducing the chance of the wound splitting open.14PubMed Central. Comparative analysis of the therapeutic effects of cosmetic tension-reducing suturing technique and traditional suturing technique in 120 patients with maxillofacial trauma You cannot control how your surgeon placed the stitches, but you can minimize tension on facial wounds by avoiding extreme facial expressions, not chewing gum or tough foods if the wound is near your jaw, and being gentle when washing your face.
Wounds over joints present a different problem. Elbows, knees, and knuckles flex repeatedly throughout the day, which puts stress on sutures. Keeping the joint relatively still for the first few days, or using adhesive wound-closure strips to reinforce the area, can help prevent the wound edges from pulling apart. Wounds on the scalp bleed aggressively but also heal quickly due to rich blood supply, while wounds on the shins and feet heal slowly because blood flow to the lower extremities is comparatively poor, especially in older adults or people with diabetes.
Managing the Scar After Stitches Come Out
What you do in the weeks and months after suture removal has as much impact on the final scar as what you did while the stitches were in. Silicone-based products, available as sheets or gels, are the best-studied option for scar management. A controlled trial of silicone gel applied after surgery found significant improvements in scar vascularity, pigmentation, pliability, height, and itchiness compared to placebo.15PubMed Central. Evaluating Silicone Gel Efficacy in Reducing Scar Formation Following Microscopic Inguinal Varicocelectomy: A Double-Blind Prospective Controlled Trial A comparative study of different scar treatments in cesarean section patients found that silicone gel sheeting was effective enough to be considered a first-line therapy, with steroid injections reserved as a second option for scars that become raised or hypertrophic.16Medicine in Evolution. A comparative clinical study of the treatment of hypertrophic scars with intralesional steroid and silicone gel sheeting in different types of incision lines in caesarean sections
Sun protection is another crucial and frequently overlooked step. Fresh scar tissue is highly susceptible to UV damage, which can cause permanent darkening or discoloration. Covering a new scar with sunscreen or clothing for at least six to twelve months after healing gives the tissue its best chance of blending in with the surrounding skin. Scar massage, which involves firmly rubbing the healed scar in circular motions for a few minutes daily, can help break down excess collagen and improve the scar’s texture over time.4PubMed Central.

Honey, Aloe, and Other Natural Alternatives
Medical-grade honey has genuine antibacterial properties and a growing body of evidence behind it. Manuka honey in particular has shown activity against antibiotic-resistant bacteria like MRSA in laboratory and preclinical research, and vacuum-treated manuka honey trended toward faster wound closure in wound-healing assays.17PubMed Central. Manuka honey microneedles for enhanced wound healing and the prevention and/or treatment of Methicillin-resistant Staphylococcus aureus (MRSA) surgical site infection In a clinical study on sutured skin wounds in horses, honey applied into the wound bed before closure dramatically reduced infection rates compared to controls.18Drug Resistance Updates. Revolutionizing non-conventional wound healing using honey by simultaneously targeting multiple molecular mechanisms
The caveat is important: most of these findings come from animal studies, laboratory experiments, or specialized medical-grade formulations, not grocery store honey. Raw honey from a jar may contain spores and other contaminants that you do not want in an open wound. If you are interested in honey-based wound care, look for products specifically labeled as medical-grade and discuss it with your doctor before applying anything unconventional to your stitches.
Aloe vera has some evidence behind it as well, though it is thinner. A rat study found that topical aloe vera gel significantly accelerated wound healing compared to coconut oil and cold cream in terms of clinical, histological, and biochemical measures.19PubMed Central. Comparison of the effects of Aloe vera gel and coconut oil on the healing of open wounds in rats A small randomized trial in women after cesarean sections found positive effects of aloe vera dressings on wound healing.20PubMed Central. Aloe vera gel and cesarean wound healing; a randomized controlled clinical trial These results are encouraging but limited, and aloe vera gel from a drugstore often contains added fragrances, alcohol, or preservatives that could irritate a fresh wound. If you want to try it, use pure aloe gel and keep petroleum jelly as your baseline.
Nutrition and Healing From the Inside
What you put on a wound matters, but what you put into your body matters too. Vitamin C plays a direct role in building collagen, the protein that gives healing tissue its structural strength. It also supports the proliferation of fibroblasts, the cells that build new connective tissue in a wound bed.21PubMed Central. A Systematic Review on the Role of Vitamin C in Tissue Healing You do not need megadoses. If you eat a reasonable amount of fruits and vegetables, you are probably getting enough. But people who are deficient, including smokers, heavy drinkers, and those on extremely restrictive diets, may heal noticeably slower. Protein intake is also critical because wound repair is an energy-intensive process that demands amino acids for new tissue construction. If you just had a procedure and are thinking about what to eat, a diet with adequate protein, vitamin C, and zinc gives your body the raw materials it needs.
Smoking deserves a specific callout here. Nicotine constricts blood vessels and reduces oxygen delivery to healing tissue. Surgeons routinely ask patients to stop smoking weeks before and after elective procedures for exactly this reason. If you have stitches and you smoke, the topical products you use are fighting an uphill battle against reduced blood flow.
When to Call Your Doctor
Good wound care prevents most complications, but some problems need professional attention. Watch for increasing redness that spreads beyond the wound edges, warmth or swelling that gets worse instead of better after the first couple of days, pus or foul-smelling drainage, fever, or wound edges that start pulling apart. A thin line of redness right at the suture site is normal for the first day or two and does not indicate infection. What you are looking for is redness that expands outward from the wound, forms streaks, or appears days after the procedure when things had seemed to be improving.
If you notice a suture has popped out or the wound edges are gapping, cover the area with a clean bandage, apply gentle pressure if there is bleeding, and contact your surgeon’s office. Small areas of wound separation can sometimes heal on their own with careful wound care, but your doctor should assess whether additional closure is needed. Acting quickly when something looks wrong is far more valuable than any product you can buy at the drugstore.
