What Not to Do After Brazilian Laser Hair Removal

Youmna Rehman • May 24, 2025

Brazilian laser hair removal can leave your skin feeling incredibly smooth—but the journey doesn’t end when the session does. What you do after the treatment is just as important as what you do before. Ignoring post-care guidelines can lead to discomfort, irritation, or even unwanted side effects like burns or pigmentation. Let’s walk through the key things you should not do after Brazilian laser hair removal, why they matter, and how to take care of your skin for the best results.


10 FAQS ABOUT FACE LASER HAIR REMOVAL!


1. Don’t Expose the Area to Direct Sunlight

Your skin is more sensitive than usual after laser treatment. Exposing the freshly treated area to sunlight (or tanning beds) can cause burns, hyperpigmentation, and delayed healing.

Why avoid it?
UV exposure post-laser can trigger inflammation and dark spots because the skin's natural protective barrier is temporarily compromised.

What to do instead:
Wear loose-fitting clothing to shield the area and avoid tanning completely for at least 7–10 days after the session. If you’re going out, apply a broad-spectrum SPF 30+ sunscreen even over the bikini line if it’s exposed (e.g., at the beach).


2. Don’t Take Hot Showers, Baths, or Saunas

Heat can aggravate the skin, increasing the risk of irritation, redness, and sensitivity.

Why avoid it?
The treated area is already warm from the laser's thermal energy. Introducing additional heat from hot water or steam can worsen inflammation or even lead to blistering in sensitive skin.

What to do instead:
Take lukewarm showers for the next 48 hours. Avoid saunas, steam rooms, and hot tubs for at least 2–3 days post-treatment.


3. Don’t Wear Tight or Non-Breathable Clothing

That sexy, tight yoga pants or synthetic underwear? A no-go right after your laser session.

Why avoid it?
Tight clothing traps heat and sweat, creating the perfect environment for folliculitis (inflammation of the hair follicles), friction burns, or ingrown hairs.

What to do instead:
Opt for cotton underwear, breathable fabrics, and loose-fitting bottoms for at least 2–3 days to allow your skin to breathe and heal comfortably.


4. Don’t Work Out Right Away

Yes, we know skipping the gym isn’t ideal—but trust us, it’s worth it.

Why avoid it?
Working out increases body temperature and sweating, which can irritate the treated area and increase the risk of bacterial infection or post-treatment rash.

What to do instead:
Skip the gym for at least 24–48 hours. Once the skin has calmed down and isn’t red or sensitive, you can slowly return to physical activity.


5. Don’t Exfoliate or Scrub the Area

Many people think exfoliating right after will help with hair shedding. Not true.

Why avoid it?
Scrubbing can damage the freshly lasered skin, cause micro-tears, and increase sensitivity or scabbing. The skin is already mildly inflamed; you don’t want to provoke it further.

What to do instead:
Wait about 5–7 days, then gently exfoliate using a mild scrub or a soft loofah to help with the natural shedding phase.


6. Don’t Apply Harsh Skincare Products

Steer clear of retinoids, benzoyl peroxide, glycolic/salicylic acid, alcohol-based toners, and heavily fragranced lotions.

Why avoid it?
These products can strip the skin, disturb the healing process, and cause stinging or chemical burns in a sensitized area.

What to do instead:
Use aloe vera gel, fragrance-free moisturizers, or post-laser calming creams recommended by your technician.


7. Don’t Shave Immediately After Treatment

Shaving can irritate the skin and make post-laser side effects worse.

Why avoid it?
The area is already healing, and shaving might cause cuts, razor burn, or ingrown hairs.

What to do instead:
Wait at least 4–5 days before shaving, or until the area no longer feels sensitive.


8. Don’t Pick or Scratch the Skin

If you’re going through the shedding phase or experiencing some itching—don’t scratch.

Why avoid it?
Scratching or picking can break the skin and lead to scarring, infection, or hyperpigmentation.

What to do instead:
Apply a soothing, cooling product like aloe vera or a hydrocortisone cream (if approved by your technician).


9. Don’t Book Waxing or Threading Appointments

This one’s major. Avoid all forms of hair removal that pull from the root.

Why avoid it?
Laser hair removal targets the root of the hair, and waxing, plucking, or threading can remove the follicle, making the treatment ineffective.

What to do instead:
Stick to shaving between sessions and keep your appointments consistent for best results.


10. Don’t Skip Post-Treatment Instructions from Your Technician

Every skin type is different. What works for your friend might not work for you.

Why avoid it?
Skipping your clinic’s advice can result in poor results or increased risk of side effects specific to your skin or hair type.

What to do instead:
Follow all instructions provided by your laser specialist, and don’t hesitate to call if you have any concerns or abnormal reactions.


Final Thoughts: Post-Laser Discipline = Long-Term Smoothness

Brazilian laser hair removal is a fantastic investment in your self-care routine, but what you do after the session truly shapes your results. Avoiding irritation, infection, or other complications is as easy as being mindful for a few days. Skip the tight leggings, hold off on the hot yoga, and baby that bikini area like you would sunburnt skin.

Consistency + aftercare = silky, smooth success.

By Youmna Rehman August 22, 2025
Laser hair removal for the bikini area can give you smooth, hair-free skin — but only if you prepare and care for your skin properly. Many people underestimate the role that pre- and post-care play in the effectiveness of bikini laser sessions. If you make certain mistakes, you risk side effects like irritation, burns, hyperpigmentation, or even reduced results. In this comprehensive guide, we’ll walk you through everything you should avoid before and after your bikini laser hair removal sessions so you can achieve the safest, smoothest, and longest-lasting results possible. How to Prepare for Your First Bikini Laser Hair Removal Session Why Pre- and Post-Care Matters for Bikini Laser Hair Removal Laser hair removal works by targeting pigment in the hair follicle and destroying it with concentrated light. For the treatment to be safe and effective, your skin needs to be in its most natural, irritation-free state. Certain activities — like tanning, exfoliating, or using harsh products — can make your skin more sensitive and prone to burns, while others can interfere with the laser’s ability to reach the hair follicles. Likewise, after your session, the treated area is temporarily sensitive, making it more prone to irritation, infection, and hyperpigmentation if you’re not careful. What Not to Do Before Bikini Laser Hair Removal 1. Do Not Wax, Epilate, or Thread Laser hair removal requires the hair root to be intact for the laser to target it effectively. Waxing, epilating, or threading removes the follicle, making the session ineffective. What to do instead: Shave the area 24 hours before your appointment — this leaves the root intact but removes the surface hair, preventing burns. 2. Avoid Tanning or Sun Exposure Both natural sunbathing and tanning beds make your skin more sensitive to the laser, increasing the risk of burns and hyperpigmentation. Tip: Stay out of the sun for at least 2 weeks before your session and always use sunscreen on exposed areas. 3. Stop Using Self-Tanners Self-tanning products add artificial pigment to the skin, which can confuse the laser and lead to uneven results or burns. Pro tip: Avoid all self-tanners for at least 10 days prior t o your appointment. 4. Don’t Use Harsh Skincare Products Products containing retinoids, glycolic acid, salicylic acid, benzoyl peroxide, or AHAs can make your skin extra sensitive and prone to burns. Instead: Stick to mild, fragrance-free cleansers and moisturizers on your bikini area for a few days before treatment. 5. Avoid Perfumes, Deodorants, and Lotions on the Day Before your appointment, make sure your bikini area is completely clean and product-free. Perfumes, deodorants, lotions, or oils can react with the laser and cause irritation. 6. Skip Exfoliation and Scrubs While exfoliation is great for preventing ingrown hairs, avoid it at least 48 hours before your bikini laser session. Freshly exfoliated skin is more vulnerable to burns and irritation. 7. Don’t Take Blood-Thinning Medications Without Consultation Medications like aspirin, ibuprofen, and certain supplements can increase the risk of bruising. Always check with your dermatologist if you’re on any medications before your appointment. 8. Avoid Tight Clothing Before Your Session Tight underwear or pants can cause friction and irritation right before your session. Loose cotton clothing is best. What Not to Do After Bikini Laser Hair Removal Your skin will be more sensitive after laser treatment, and improper care can lead to burns, hyperpigmentation, or ingrown hairs . Here’s what to avoid: 1. Don’t Expose the Area to the Sun Avoid tanning, sunbathing, and direct sun exposure for at least 2 weeks after your session. Freshly treated skin is prone to dark spots and burns when exposed to UV rays. Pro tip: Use a mineral sunscreen if there’s any chance of sun exposure. 2. Don’t Shave Immediately While shaving i s allowed during your laser treatment period, avoid shaving for at least 48–72 hours after your session to prevent irri tation. 3. Skip Hot Showers, Saunas, and Pools Heat can worsen sensitivity and increase the risk of burns. Avoid: Hot showers or baths Saunas and steam rooms Swimming pools with chlorine Stick to cool or lukewarm water for at least 48 hours after treatment. 4. Avoid Scrubs and Exfoliation Do not exfoliate your bikini area for at least a week after laser hair removal . The skin needs time to heal, and scrubbing can cause redness, irritation, or even microtears. 5. Don’t Use Harsh Skincare Products Stay away from active ingredients like retinoids, glycolic acid, salicylic acid, and AHAs for 5–7 days post-treatment. Stick to mild, fragrance-free moisturizers instead. 6. Avoid Tight Clothing Wearing tight underwear or jeans immediately after your session can trap heat and cause irritation. Opt for loose, breathable fabrics like cotton. 7. Don’t Scratch or Pick at the Area Some people experience mild itching or dryness after treatment, but scratching can lead to scarring or infection. Use a soothing aloe vera gel or dermatologist-recommended lotion instead. 8. Don’t Schedule Waxing or Threading Just like before treatment, do not wax, thread, or epilate the area between sessions — it removes the hair root, reducing the laser’s effectiveness. Stick to shaving if needed. What’s the Difference Between Bikini Line, Bikini Full, and Brazilian Laser? Additional Tips for Better Results Moisturize regularly — keeping the skin hydrated speeds up recovery. Stay consistent with sessions — bikini laser hair removal usually takes 6–8 treatments spaced 4–6 weeks apart for optimal results. Communicate with your technician — if you notice redness, irritation, or unexpected side effects, let your provider know immediately. Final Thoughts Getting smooth, hair-free skin from bikini laser hair removal depends just as much on what you do outside the clinic as the treatment itself. Avoiding certain habits before and after your sessions helps protect your skin, reduces side effects, and ensures you get the best, long-lasting results. If you’re ever unsure about products, medications, or activities, consult your laser technician or dermatologist for personalized advice.
