Getting rid of acne requires targeting the root causes: excess oil production, clogged pores, bacteria, and inflammation. Most people can significantly improve their skin with the right combination of over-the-counter products, but the specific approach depends on the type and severity of your acne. Mild breakouts often respond to topical treatments within a few weeks, while deeper or hormonal acne may need prescription options. The key is choosing treatments that address multiple causes at once and sticking with them long enough to work.
Start With the Right Over-the-Counter Products
Two ingredients dominate the over-the-counter acne aisle: benzoyl peroxide and salicylic acid. Both work, but they do different things. Benzoyl peroxide kills acne-causing bacteria and is generally more effective at clearing clogged pores (blackheads and whiteheads). Salicylic acid dissolves oil inside pores and reduces inflammation, making it a better fit for oily skin with smaller, surface-level breakouts. In clinical comparisons, a 2.5% benzoyl peroxide regimen outperformed a 0.5% salicylic acid regimen for non-inflammatory lesions like blackheads.
You don’t have to pick just one. Current dermatology guidelines specifically recommend combining topical therapies with multiple mechanisms of action. A common starting routine looks like this:
- Cleanser: A gentle, non-comedogenic face wash (with or without salicylic acid) used twice daily
- Treatment: A thin layer of benzoyl peroxide (2.5% to 5%) applied to acne-prone areas
- Moisturizer: A lightweight, oil-free moisturizer to prevent dryness and irritation
- Sunscreen: A non-comedogenic SPF 30+ in the morning, since many acne treatments increase sun sensitivity
Start with lower concentrations. A 2.5% benzoyl peroxide works nearly as well as 10% with far less irritation. If your skin tolerates it after a couple of weeks, you can increase the strength.
When to Add a Retinoid
If basic cleansing and benzoyl peroxide aren’t enough, a topical retinoid is the next step. Adapalene (available over the counter at 0.1%) speeds up skin cell turnover so dead cells don’t pile up and clog pores. It’s especially effective for comedonal acne, the type that shows up as persistent blackheads and small bumps under the skin’s surface.
Retinoids require patience. During the first three weeks, your skin will likely look worse before it improves. This is normal purging: the product pushes existing clogs to the surface faster than they would have appeared on their own. Purging typically lasts four to six weeks, shows up in areas where you already tend to break out, and produces smaller blemishes that heal quickly. If new breakouts appear in unusual spots, grow deeper or more painful, or persist beyond six weeks, the product itself may be irritating your skin rather than helping it.
Full results from adapalene take about 12 weeks of consistent daily use. Apply it at night (retinoids break down in sunlight), start with every other night if your skin is sensitive, and always pair it with moisturizer. Avoid using benzoyl peroxide and retinoids at the same time of day, since benzoyl peroxide can deactivate some retinoid formulas. Use one in the morning and the other at night.
Hormonal Acne Needs a Different Approach
If your breakouts cluster along your jawline, chin, and lower face, flare around your period, and don’t respond well to topical treatments, you’re likely dealing with hormonal acne. This type is driven by androgens (hormones that stimulate oil production) and is common in women from their mid-20s onward.
Two prescription options have strong evidence behind them. Spironolactone, originally a blood pressure medication, blocks the effects of androgens on oil glands. In one review of 85 women, a third achieved complete clearing and another third saw noticeable improvement. Broader studies show a 50% to 100% reduction in acne. It’s prescribed only for women and typically takes two to three months to show results.
Birth control pills that contain both estrogen and a progestin are another effective option. The FDA has approved several oral contraceptives specifically for acne treatment, and they work against all types of lesions: blackheads, whiteheads, pimples, and even deeper cysts. These also take a few months to reach full effect.
Options for Severe or Resistant Acne
When topical treatments and hormonal therapy haven’t worked, oral antibiotics can help bring a bad flare under control. Dermatologists typically prescribe them for a limited course alongside topical treatments, not as a long-term solution. The goal is to knock down bacteria and inflammation quickly, then maintain results with topicals alone.
For the most severe, scarring, or treatment-resistant acne, isotretinoin (formerly known by the brand name Accutane) remains the most powerful option available. It shrinks oil glands, reduces bacteria, prevents clogging, and calms inflammation, addressing all four causes of acne simultaneously. A typical course lasts four to six months, and many people experience long-term or permanent clearing afterward.
Isotretinoin comes with significant requirements. It causes birth defects, so anyone who could become pregnant must use two forms of contraception and enroll in a monitoring program called iPLEDGE. Side effects like dry skin, dry lips, and joint aches are common during treatment. It’s a serious medication, but for people who’ve tried everything else, it can be genuinely life-changing.
What Your Diet Actually Has to Do With It
Diet doesn’t cause acne on its own, but certain foods can make it worse. The strongest evidence points to dairy. A meta-analysis in Clinical Nutrition found that people with the highest dairy intake were more than two and a half times as likely to have acne compared to those who consumed the least. Skim milk showed a stronger association than whole milk, and interestingly, yogurt and cheese showed no significant link at all. The likely explanation is that milk contains hormones and growth factors that stimulate oil production.
High-glycemic foods, things that spike your blood sugar quickly like white bread, sugary drinks, and processed snacks, also appear to worsen acne by triggering insulin surges that increase oil production and inflammation. You don’t need to overhaul your entire diet, but if you’re doing everything else right and still breaking out, cutting back on sugary processed foods and swapping some dairy milk for an alternative is a reasonable experiment.
Protecting Your Skin While Treating It
Acne treatments work better when your overall routine isn’t fighting against them. Every product you put on your face, from makeup to sunscreen to moisturizer, should be labeled non-comedogenic, meaning it’s formulated to avoid clogging pores. That said, there’s no official regulatory standard for this term, so the label alone isn’t a guarantee. If a new product causes fresh breakouts within a couple of weeks, stop using it regardless of what the packaging says.
A few practical habits make a real difference. Wash your face after sweating, since sweat mixed with oil and bacteria is a fast track to clogged pores. Change pillowcases at least weekly. Avoid touching your face throughout the day. And resist the urge to pick or pop pimples. Squeezing a pimple pushes bacteria deeper into the skin and dramatically increases the risk of scarring and dark marks that can take months to fade.
Dealing With Marks After Acne Clears
Even after a pimple heals, it often leaves behind a mark. On lighter skin tones, these tend to be flat pink or red spots called post-inflammatory erythema. On darker skin tones, they’re more likely to be brown or dark patches called post-inflammatory hyperpigmentation. Neither is a true scar, and both fade on their own over time, but that process can take anywhere from three months to over a year without treatment.
Topical retinoids and vitamin C serums can speed fading. Sunscreen is critical here too, because UV exposure darkens these marks and extends their lifespan significantly. If you have actual indented or raised scars (not just flat discoloration), those typically require professional treatments like chemical peels, microneedling, or laser therapy. The single best way to prevent scarring is to treat active acne early and consistently, and to never pick at your skin.
How Long Clearing Takes
The hardest part of acne treatment is the timeline. Most topical treatments need 8 to 12 weeks of daily use before you can fairly judge whether they’re working. Hormonal treatments take two to three months. Even prescription-strength retinoids make your skin worse for the first few weeks before improving it. Starting a new product, getting impatient after two weeks, and switching to something else is one of the most common reasons people feel like nothing works.
Pick a regimen, give it a full three months, and track your skin with weekly photos so you can spot gradual improvement you might not notice in the mirror. If you’ve genuinely committed to a routine for that long and aren’t seeing results, that’s the point to escalate, whether that means adding a retinoid, asking about hormonal options, or discussing isotretinoin with a dermatologist.
