Laser treatment for broken capillaries (telangiectasias) uses concentrated light energy to target damaged blood vessels beneath the skin. This process, called selective photothermolysis, involves the laser’s energy being absorbed by the hemoglobin within the capillary, converting light into heat. The heat causes the targeted vessel to collapse and seal shut, which the body naturally reabsorbs over time. Understanding the recovery process helps manage expectations and ensures the best outcome.
Immediate Post-Treatment Appearance
Following the procedure, the treated skin will exhibit several temporary and expected changes, which indicates the treatment was effective. The most common immediate effect is erythema (redness), often accompanied by a sensation similar to a mild sunburn. This reaction is a natural inflammatory response as the body begins healing after the heat energy is applied.
Mild swelling (edema) is also a common occurrence, especially in delicate areas like around the eyes. The treated capillaries may temporarily look darker, gray, or purple, known as purpura. Purpura is a form of bruising that occurs when the treated vessel walls rupture, indicating the laser successfully targeted the vessel.
The Sequential Healing Timeline
Initial redness and swelling typically begin to subside quickly, often resolving within one to three days following the laser session. During this recovery stage, the skin may feel slightly tight or dry as the superficial inflammation decreases. Applying a cold compress or ice pack intermittently on the day of the procedure can help minimize this initial swelling.
Purpura, the darker appearance of treated vessels, is the longest-lasting immediate side effect, generally taking one to two weeks to fully fade. This darkening occurs as the body’s immune system sends specialized cells to break down and clear the coagulated capillary fragments. Depending on laser intensity and vessel size, temporary crusting or tiny scabs may form, which should naturally flake off within seven to ten days.
The ultimate result of the treated capillaries diminishing noticeably becomes apparent around two to four weeks after the session.
Essential Post-Procedure Care
Sun Protection
Protecting the skin from sun exposure is mandatory following laser treatment to prevent complications like hyperpigmentation and ensure optimal results. A broad-spectrum sunscreen with an SPF of 30 or higher must be applied daily, even on cloudy days or when indoors, as UV rays can penetrate windows. It is also highly recommended to wear protective clothing, such as wide-brimmed hats, to physically shield the treated area from direct sunlight.
Cleansing and Restrictions
The treated skin barrier is temporarily compromised, requiring a gentle cleansing and moisturizing routine to support healing. Use a mild, non-abrasive, fragrance-free cleanser, and pat the skin dry with a soft towel rather than rubbing. Avoid makeup application until any scabbing or crusting has fully resolved, which may take up to 48 hours to one week, depending on the intensity of the treatment.
For a period of at least three to five days post-treatment, avoid exposing the skin to excessive heat, which can exacerbate swelling and redness. This includes strenuous exercise that causes flushing, hot tubs, saunas, and steam rooms. Additionally, refrain from using any harsh topical irritants or exfoliants, such as retinoids or glycolic acids, for one to two weeks, or until your provider gives clearance.
Understanding Results and Follow-Up
While some patients may notice an immediate reduction in the appearance of vessels, the final, true results are typically visible only after all post-treatment effects, especially the purpura, have completely resolved. The body requires approximately two to four weeks for the immune system to fully reabsorb the sealed-off capillaries. The gradual fading of the treated vessels continues over this period, leading to a clearer complexion.
It is important to manage expectations, as a single laser session may not eliminate all visible capillaries, particularly if the treatment area is extensive or the vessels are large. Many individuals require a series of two to four treatment sessions, spaced four to six weeks apart, to achieve the most satisfying, comprehensive reduction. To maintain the results long-term and prevent new capillaries from forming, minimizing sun exposure and making necessary lifestyle changes are necessary, with occasional maintenance treatments often recommended every one to two years.
