The Ultimate Guide to Post-Laser Skincare

We love laser treatments because they can deliver healthier, more rejuvenated-looking skin in less than an hour. From correcting sun damage and uneven pigmentation to minimizing fine lines, wrinkles, and acne scars, lasers are among the most versatile tools in aesthetic medicine. —that’s why they rank as the most popular minimally invasive treatment in the US, right behind neuromodulators and hyaluronic acid (HA) fillers.

But, what happens after your appointment is just as important as the treatment itself. Whether you've undergone a gentle fractional laser or an intensive ablative resurfacing procedure, proper aftercare plays a critical role in healing, minimizing complications, and optimizing results. Ahead, we’ll explore what to expect during recovery, which products to use (and avoid), and expert-recommended laser healing tips.

How long does laser recovery take?

Recovery time depends on the type of laser treatment and individual. Gentle, non-ablative lasers often cause temporary redness and mild swelling that resolve within a few hours to a few days while more aggressive resurfacing lasers can trigger peeling, crusting, and noticeable redness that may require one to two weeks of downtime. It's also important to remember that visible healing and biological healing aren't always the same thing. Even after the skin appears recovered, collagen remodeling and skin renewal can continue for weeks or months, with results gradually improving over time.

How does recovery differ between fractional and ablative lasers?

While both treatments use laser energy to create controlled skin injury, fractional lasers deliver energy in a targeted grid-like pattern of microscopic treatment zones whereas ablative lasers vaporize portions of the skin's surface, creating a more extensive wound-healing response. Because of this, fractional lasers have significantly less downtime. Most patients experience redness and swelling for the first day or two, followed by a rough, bronzed texture as the skin begins to shed. By days three to five, flaking often becomes more noticeable, but is typically resolved within a week.

Ablative lasers (such as CO2 and Erbium lasers), on the other hand, can take weeks to heal. The first several days may involve redness, swelling, crusting, and oozing, followed by peeling that can last one to two weeks. Even after the skin's surface has healed, residual redness may persist for several more weeks as the skin continues to recover.

Why does aftercare impact outcomes?

Laser treatments work by creating controlled injury in the skin, triggering a cascade of healing processes that ultimately improve tone, texture, and overall skin quality. The days and weeks following treatment are when much of that repair takes place, making proper aftercare essential. Supporting the skin barrier with gentle cleansers, moisturizers, and sun protection can help minimize inflammation and reduce the risk of complications such as infection, prolonged redness, and post-inflammatory hyperpigmentation. Conversely, using harsh products, picking at peeling skin, or exposing healing skin to UV radiation can disrupt recovery and compromise results.

What should I use after laser treatment?

After a laser treatment, you'll want to use the mildest skincare products possible. Ideally, they should be gentle, non-foaming, and fragrance-free to support the skin barrier while minimizing irritation. AEDIT Founder and board-certified facial plastic and reconstructive surgeon Dr. William Kennedy highlights, "Immediately after laser treatments, I typically recommend three essentials: a gentle cleanser like CeraVe Hydrating Cleanser, a restorative moisturizer such as Alastin Soothe + Protect Recovery Balm or SkinCeuticals Epidermal Repair, and a mineral SPF 30 or higher. Patients often think they need a complicated routine, but in reality, the best results come from protecting the skin while it heals."

Sunscreen is particularly important, as healing skin is more vulnerable to UV damage and post-treatment discoloration. For more intensive treatments, healing ointments such as petrolatum-based products may be necessary during the initial recovery period. That said, your provider should always supply personalized aftercare instructions based on the specific laser used, your skin type, and your treatment goals.

Which ingredients accelerate healing?

When it comes to laser resurfacing recovery, the goal isn't necessarily to speed up healing so much as it is to support the skin's natural repair process. Ingredients that help reinforce the skin barrier and maintain hydration tend to be the most beneficial.

Hyaluronic acid can help attract moisture, while ceramides support barrier function and reduce transepidermal water loss. After more intensive treatments, petrolatum-based ointments are often recommended because they create a protective environment for healing skin. Depending on the procedure, your provider may also suggest growth factors or specialized recovery products.

What products should I avoid?

While your skin is healing, it's best to avoid products that can increase irritation or disrupt the skin barrier. This typically includes retinoids, alpha and beta hydroxy acids, exfoliating scrubs, benzoyl peroxide, and other potentially sensitizing active ingredients. Fragranced skincare products can also cause unnecessary irritation, particularly in the days immediately following treatment. "After a laser treatment, your skin barrier is temporarily compromised, making it far more susceptible to irritation. Introducing active ingredients too soon can trigger excessive inflammation, prolong redness, delay healing, and in some patients increase the risk of post-inflammatory hyperpigmentation. More aggressive irritation, especially after ablative procedures, may even contribute to infection or scarring. The safest approach is to let the skin heal first before gradually reintroducing your regular skincare routine," says Dr. Kennedy.

Can I use retinol after laser treatment?

Not right away. Retinoids, including retinol and prescription-strength tretinoin, can increase irritation and compromise an already vulnerable skin barrier. Most providers recommend pausing these products a few days before treatment and waiting until the skin has fully healed before reintroducing them.

According to Dr. Kennedy, “Patients are often able to resume retinoids sooner after non-ablative fractional laser treatments—sometimes within one to two weeks once the skin has fully re-epithelialized and irritation has resolved. Following a more aggressive ablative laser, however, it's common to wait several weeks or longer before reintroducing retinoids, depending on how the skin is healing. Patients should always follow their treating provider's post-procedure instructions rather than a fixed timeline." Your provider will be able to recommend a timeline tailored to your treatment, skin type, and recovery progress.

How can patients minimize hyperpigmentation risk?

One of the most effective ways to minimize the risk of post-inflammatory hyperpigmentation (PIH) after a laser treatment is to protect healing skin from the sun. UV exposure can trigger excess pigment production during the recovery process, making diligent sunscreen use and sun avoidance essential. Patients should also follow their provider's aftercare instructions closely and avoid picking, peeling, or using irritating skincare products before the skin has fully healed. For individuals with darker skin tones or a history of hyperpigmentation, providers may recommend pretreatment skincare, adjusted laser settings, or specialized post-procedure products to further reduce the risk of unwanted pigmentation changes.

When can I wear makeup after laser resurfacing?

The answer depends on the type of laser treatment and how quickly your skin heals. After a light fractional laser, many patients can resume wearing makeup once the skin has fully re-epithelialized, typically within a few days. Following more aggressive ablative resurfacing, providers often recommend waiting until the skin has completely healed, which may take one to two weeks or longer. Applying makeup too soon can increase irritation, introduce bacteria, and interfere with the healing process. If you still have open wounds, peeling, or excessively sensitive skin, it’s too soon.

When can I exercise after laser procedures?

It's generally best to avoid strenuous exercise immediately after a laser treatment. Increased body temperature, sweating, and friction can aggravate inflammation, prolong redness, and potentially interfere with the healing process. Following a lighter fractional laser, many patients can return to their normal workout routine within a day or two. More intensive ablative treatments often require a longer break, sometimes a week or more, depending on the extent of healing.

What mistakes commonly compromise results?

The most common laser aftercare mistake is failing to protect the skin from sun exposure. UV radiation can worsen inflammation, trigger hyperpigmentation, and undermine the benefits of treatment. Other frequent missteps include resuming active ingredients too soon, picking or peeling flaking skin, and using harsh exfoliants before the skin barrier has fully recovered. Patients may also be tempted to overcomplicate their routine with multiple recovery products, but more isn't always better. In most cases, a simple regimen focused on gentle cleansing, hydration, and protection yields the best results.
