After laser hair removal, redness and small raised bumps around the follicles are expected and usually settle within hours to a day. Keep the area cool, avoid heat, friction and sun, and do not pick. Small scabs sometimes form where hair was dense or dark; they come away on their own. Treated hairs shed over one to three weeks.

The first two days

Redness and small raised bumps around the follicles look a little like goosebumps and usually settle within hours to a day. Apply cool compresses, wear loose clothing, and avoid hot showers, saunas, strenuous exercise and perfumed products on the area for a day or two. Gentle, fragrance-free deodorant can usually be used after a day.

Scabs, crusts and shedding

Small scabs sometimes form over areas of dense, dark hair where more energy was absorbed. Leave them to fall away and keep the area moisturised; picking increases the risk of marks. Treated hairs push out and shed over one to three weeks, which can look like regrowth. Shaving between sessions is fine; waxing and plucking remove the hair the laser needs to target.

Sun and pigment

Avoid sun and tanning on treated areas before and after sessions. Tanned skin absorbs more energy, raising the risk of burns, blistering and pigment change. Blisters, spreading redness or dark or light patches should be reviewed.

Questions after treatment come back through WhatsApp at +65 8023 7170 during clinic hours (Monday to Friday 10am to 8pm, Saturday 11am to 3pm, Singapore time). Anything that is getting worse rather than better, a blister or open area, or fever needs to be seen the same day, wherever you are.
