Laser hair removal uses concentrated light to target and destroy hair follicles, providing long-term reduction of unwanted hair. It is one of the most popular aesthetic treatments in Korea for all skin types.
Laser hair removal works by directing pulses of laser light into hair follicles. The pigment (melanin) in the hair absorbs the light energy, which converts to heat and damages the follicle — inhibiting future hair growth. Modern laser technology, including Nd:YAG lasers, is safe and effective for a wide range of skin tones.
The procedure requires multiple sessions because hair grows in cycles — laser is most effective during the active growth phase (anagen). Most patients require 6–8 sessions spaced 4–6 weeks apart for optimal results. Following a full course of treatment, many patients see an 80–90% permanent reduction in hair growth.
In Korea, laser hair removal must be performed in licensed clinics by trained technicians or medical professionals. Sun protection before and after sessions is important to prevent hyperpigmentation, particularly during Korea's strong summer UV season. Avoid sun exposure for at least 2 weeks before and after each session, and always apply SPF 50+ sunscreen when outdoors.
