You’ve seen the before-and-afters: smooth, even skin, fewer fine lines, that fresh, luminous look that seems impossible to fake. You’ve finally decided to try laser skin resurfacing for yourself (like CoolPeel, a CO2 laser, or a similar treatment) and now you’re wondering what comes next.
That in-between moment, right after booking but before treatment, is important. Preparing well means your skin barrier is strong, your healing process runs smoothly, and you walk away with the glow you were promised. Here’s how to get your skin ready for it.
Laser resurfacing sounds high-tech, but at its core, it’s simple science: the laser removes the outer layer of skin to make way for new skin that’s brighter, smoother, and more even. That process triggers collagen production, the body’s natural way of repairing and firming tissue.
The better condition your skin is in before the procedure, the easier it will heal afterward. Weak or irritated skin can react poorly, leading to longer downtime, dryness, or uneven tone. That’s why your provider will give you specific pre-treatment instructions.
Proper preparation minimizes the risk of irritation, post-inflammatory hyperpigmentation, and other adverse reactions, especially for those with darker skin tones or a history of sensitivity.
Healthy, hydrated skin heals faster. That’s the goal in the weeks leading up to your laser treatment.
Start by avoiding sun exposure as much as possible. That means skipping tanning beds, self-tanners, and direct sunlight for at least two weeks before your appointment. Sunburned or tanned skin can’t be treated safely; it’s too reactive, and lasers need a calm, even surface to work properly.
If your provider suggests it, switch to fragrance-free skincare products and a gentle cleanser that won’t strip your skin barrier. Put aside chemical exfoliants like glycolic acid or vitamin E serums until you’re cleared to use them again after treatment.
It’s also important to review your medical history with your provider. Some medications, especially blood-thinning medications or certain acne drugs, may need to be paused. If you’re prone to cold sores, an antiviral medication can help prevent flare-ups on treated skin.
Above all, focus on hydration. Stay hydrated, use a lightweight moisturizer, and avoid anything that leaves your skin feeling tight or dry. Hydrated skin equals smoother recovery later.
This is the time to double down on sun protection. You’ve probably been careful already, but in the final week, make it a habit. Apply broad-spectrum sunscreen (with at least SPF 30) daily, ideally one containing zinc oxide for physical protection.
Avoid outdoor workouts or beach days that might lead to heavy sun exposure or flushed skin. The laser can’t be used on recently tanned skin, so keep things calm.
Keep your skincare routine simple: gentle cleansing, moisturizing, and protection. Skip exfoliating pads, scrubs, or strong skincare products that promise quick fixes; they’ll just disrupt your skin barrier before treatment.
The day before your laser resurfacing, give your skin a break. No makeup, no self-tanner, no retinol. Wash your face with a gentle cleanser, pat it dry, and apply a plain moisturizer. Drink plenty of water and get solid rest. The better your skin’s moisture balance and overall skin health, the easier the healing process will be.
If you’ve been prescribed any antiviral medication, this is when you’ll likely start it. Some providers recommend avoiding caffeine or alcohol the night before to help minimize swelling.
When you arrive, your provider will go over the plan again, review your medical history, and prep the treatment area. A topical numbing cream is applied to minimize discomfort. Once you’re ready, short bursts of light energy pass over your skin.
During a CoolPeel or fractional CO2 laser session, the energy vaporizes micro-columns of skin tissue in the outer layer, prompting the body to repair itself by generating new collagen and new skin. Because the laser works in tiny patterns, it leaves surrounding tissue intact, helping you heal faster.
Some cases use Erbium lasers, especially for lighter resurfacing or darker skin tones, where a gentler wavelength reduces risk. Your provider will determine the best approach based on your skin color, sensitivity, and desired results.
A single session can address age spots, sun damage, fine lines, and various skin concerns that topical treatments can’t reach.
When it’s over, you’ll likely feel warmth, similar to a mild sunburn. Most patients say it’s manageable and short-lived.
How you care for your skin afterward matters just as much as the treatment itself. Expect some redness, mild swelling, and light peeling in the treated area over the first few days—. That’s your body revealing new skin underneath.
Follow your provider’s post-treatment instructions carefully. Most will recommend:
Once peeling subsides, apply sunscreen daily. Again, make sure it’s a broad-spectrum sunscreen with zinc oxide or titanium dioxide. This protects your fresh skin from UV rays and prevents post-inflammatory hyperpigmentation.
Stay hydrated, skip the gym or hot yoga for a few days, and resist the urge to pick or scratch. Those small decisions make a big difference in how quickly your skin resurfacing results appear.
Your healing process depends on the intensity of the procedure.
Your treated area might feel tender for a few days, and it’s normal to notice some flaking or tightness as the outer layer renews. Once your new skin emerges, it will appear smoother, brighter, and more even in tone.
Optimal results can take time. Most patients see their best glow after three to six weeks, once collagen production continues beneath the surface. Be patient, it’s worth it.
If you follow your prep and aftercare plan, you’ll not only see better results but also protect your skin health in the long run.
Laser skin resurfacing is one of the most trusted ways to refresh tired, sun-damaged skin. Whether you’re treating fine lines, age spots, or texture, preparation is the difference between good results and great ones.
Think of it as teamwork: your provider handles the technology, you handle the care. Together, you’ll create the foundation for radiant, even-toned, rejuvenated skin—the kind that doesn’t just look smooth but feels healthy.
If you’ve been thinking about a CoolPeel or CO2 laser treatment, start by treating your skin gently today. A little proper preparation now leads to a faster recovery, a stronger skin barrier, and that unmistakable post-laser glow.
