The best way to care for your skin following laser hair removal treatment is to leave your skin alone! Some people feel compelled to tweeze, wax, or shave their hair in the days after a session, but that can negatively affect your skin health.
You should also refrain from applying harsh skincare products, such as scented lotions or self-tanners. Hold off on exfoliating scrubs for 2 to 3 days. If you received laser hair removal on your underarms, then avoid wearing deodorant while you heal.
Finally, avoid direct sun, and wear a sunscreen of at least 30 SPF, as your skin is more sensitive to sun damage during the healing process.
