Laser hair removal usually requires little downtime, but treated skin may be red, swollen, warm, or tender. Good aftercare focuses on calming the skin, avoiding additional irritation, and protecting the area from ultraviolet exposure.
Follow the instructions provided by the professional who treated you. Aftercare may vary according to your skin, the device used, treatment settings, and body area. For what happens before the appointment, see our guide to preparing for your first laser session.
Quick Takeaways
- Mild redness, swelling, warmth, or discomfort may last from several hours to a few days
- A cool compress can help soothe temporary discomfort
- Avoid direct sun and tanning, and use broad-spectrum SPF 30 or higher
- Do not wax, tweeze, thread, or pluck treated hair between sessions
- Contact your provider for blistering, crusting, severe pain, infection signs, or unexpected pigment changes
The First 24-48 Hours
Treated skin can look and feel mildly sunburned. Use a clean, cool compress as needed and avoid scratching or rubbing the area. Use only soothing products approved by your provider.
Many clinics advise avoiding very hot showers, saunas, hot tubs, intense exercise, and other sources of heat or friction for a short period. Follow your provider’s exact timeline, especially if redness or tenderness is still present.
Protect Your Skin from the Sun
Avoid direct sun and all indoor tanning after treatment. Sun exposure can increase the risk of darkening or lightening of the treated skin and may affect when your next session can be performed.
Use a broad-spectrum, water-resistant SPF 30 or higher on exposed treated skin and reapply as directed. Your provider may recommend strict sun protection for several weeks after treatment and throughout the treatment series.
What About the Shedding Phase?
Treated hairs do not fall out immediately. They may shed over several days to weeks, and this can sometimes look like continued growth. Shedding varies, so it should not be used as the only measure of whether a treatment was successful.
Do not pull, pluck, wax, or thread the hairs. Once the skin is calm, gentle washing or light exfoliation may be allowed, but avoid aggressive scrubbing and follow your clinic’s instructions.
Products to Use and Avoid
Use gentle, fragrance-free products if your skin feels sensitive. Ask before restarting retinoids, exfoliating acids, scrubs, bleaching products, fragranced products, or other potentially irritating ingredients on the treated area.
Call your provider promptly if you notice blistering, crusting, worsening pain, spreading redness, drainage, fever, signs of infection, or a concerning change in skin color. Early assessment is safer than treating an unexpected reaction on your own.
Frequently Asked Questions
When can I shave again after a session?
Shave only after redness, swelling, and tenderness have settled and the skin surface is intact. Use a clean razor and light pressure. Your provider may recommend a specific waiting period based on the area and your skin reaction.
Can I wear makeup after facial laser treatment?
Wait until the skin is comfortable and the surface is not irritated, unless your provider gives a different instruction. When you restart makeup, use clean applicators and gentle, non-comedogenic products.
Is it normal to see little dark dots after treatment?
Small dark dots may be treated hairs remaining in the follicles before they shed. Do not pick them. Contact your provider if the dots are accompanied by significant pain, blisters, crusting, or worsening discoloration.
Final Thoughts
Aftercare should be gentle and simple: cool the skin if needed, avoid irritation, protect it from sun, and follow your provider’s instructions. Most reactions are mild, but unusual or worsening symptoms should be evaluated promptly.
