Investing in a laser treatment can dramatically improve your skin’s tone, texture, and overall appearance. Whether you’re targeting sun damage, acne scars, redness, or signs of aging, lasers offer noticeable results that build over time. But what many patients don’t realize is that results aren’t only determined by what happens in the treatment room. The skincare you use before and after your appointment plays a major role in how your skin responds, heals, and ultimately benefits.
If you’re not careful, certain products can interfere with your results or even cause irritation, inflammation, or long-term sensitivity. Knowing how to properly care for your skin before and after a procedure is just as important as choosing the right laser treatment in the first place.
How to Prep for Laser Treatment
Good results start with healthy, balanced skin. In the days leading up to your appointment, it’s best to simplify your routine and reduce the risk of irritation. This means stopping the use of certain active ingredients, especially those that thin the skin or increase photosensitivity. Retinoids, exfoliating acids, and high-strength vitamin C serums should typically be avoided for several days prior to treatment. Your provider may give you specific timing based on the type of laser and your skin type.
Sun exposure is another critical factor. Even mild tanning before a laser procedure can increase the risk of burns and post-inflammatory pigmentation. Wearing a daily broad-spectrum sunscreen with SPF 30 or higher is essential in the weeks leading up to your appointment. If you’ve had recent sunburn, a spray tan, or excessive UV exposure, it’s usually best to reschedule.
Finally, disclose all medications and topical products you’re using to your provider. Some prescriptions, such as certain antibiotics or acne medications, can make your skin more sensitive and reactive.
What to Expect After Laser
Once your treatment is complete, your skin will need time to heal. Depending on the depth and intensity of the laser used, this process can last anywhere from a few days to several weeks. During this period, the skin is more vulnerable to irritation, infection, and UV damage, so your post-treatment skincare should be focused on protection and barrier repair.
You may be tempted to apply sunscreen immediately, but this is one area where timing really matters.
Why You Shouldn’t Apply Sunscreen Right Away
In the first few days after your procedure, your skin is in a highly sensitive, compromised state. Applying sunscreen too soon can actually do more harm than good.
First, your skin barrier is impaired. Lasers, whether ablative or non-ablative, injure the top layers of the skin, making it more permeable. This means ingredients that would normally sit on the surface can now penetrate deeper and cause irritation, burning, or allergic-like reactions. Sunscreen filters and preservatives are common culprits.
Second, freshly lasered skin is similar to an open wound. Slathering sunscreen on too early can trap bacteria or debris, potentially leading to infection or clogged pores during the crucial healing window.
Even if you opt for a physical sunscreen, there’s still a risk. Many mineral formulas contain ingredients that can sting or inflame tender skin. Chemical sunscreens, in particular, are known to cause intense burning sensations when applied to freshly treated areas. Some even generate mild heat during UV exposure, something you definitely want to avoid after a procedure, as it can worsen inflammation and prolong redness.
So What Should You Do?
For the first few days (typically three to five), skip sunscreen altogether and focus on barrier-repair ointments like Aquaphor, Vaseline, or whatever healing balm your provider recommends. The goal during this stage is to protect and support re-epithelialization, the process of skin sealing over again.
Once your skin has visibly closed and the surface is no longer raw (usually around day 3 to 5 depending on the laser used), you can safely introduce a mineral-only sunscreen that contains zinc oxide or titanium dioxide. Choose a formula that is fragrance-free, alcohol-free, and designed for sensitive or post-procedure skin.
Until then, avoid direct sun exposure completely. Use a wide-brimmed hat, seek shade, and stay indoors when possible. Freshly lasered skin is prone to pigmentation and UV damage, even with brief exposure.
What Not to Use After Laser
In the days and weeks following your treatment, the focus should remain on healing. That means avoiding all ingredients that could irritate or over-stimulate the skin. This includes retinoids, alpha and beta hydroxy acids, benzoyl peroxide, vitamin C (especially in high concentrations), and any products containing alcohol, fragrance, or essential oils. Physical exfoliants and cleansing tools should also be avoided.
Even if your usual routine includes these ingredients, it’s important to pause until your provider confirms your skin is ready to resume them. Introducing actives too soon can lead to setbacks in your healing process and potentially impact your overall results.
Best Products to Support Recovery
Choosing the right post-laser products can make a visible difference in your skin’s recovery. Focus on simple, dermatologist-recommended options that support healing and reduce inflammation. A gentle cleanser like Cetaphil or La Roche-Posay’s Toleriane Hydrating Cleanser is often suitable for this stage. For moisture, rich but non-irritating options like CeraVe Healing Ointment, Avène Cicalfate+, or Vanicream can help restore the skin’s barrier. When it comes to sunscreen, mineral-based options such as EltaMD UV Physical or La Roche-Posay’s Anthelios Mineral SPF 50 are typically safe bets.
Always check with your provider before starting any new product post-treatment. Not all lasers are the same, and the needs of your skin may vary depending on the depth and area of treatment.
Protect Your Results by Protecting Your Skin
Laser treatments are an investment in your skin’s future, but their success depends heavily on what you do before and after the procedure. Avoiding the wrong products, using the right ones, and practicing good habits like consistent sun protection will give your skin the best chance to recover beautifully and maintain long-term results.
It’s easy to underestimate the importance of preparation and aftercare, but these steps are not optional. They are the foundation of a safe and effective treatment experience. So, treat your skin with the same care and attention you expect from your provider, and your results will speak for themselves.
