Primelase is a new-generation diode laser designed to excel at hair removal. No matter your skin type, it can safely remove unwanted hair on almost any area of the body, including the legs, back, shoulders, underarms, face, and bikini zone.
Most people seek out this treatment for smoother, hair-free skin, but it can also rejuvenate aging skin by stimulating new collagen production.Â
Some providers also use it to treat acne (targeting the sebaceous glands and bacteria) or lighten uneven pigmentation, including vascular or pigmented lesions.
Manufactured by Sinclair, the Primelase device offers three handpieces with different wavelengths and “spot sizes” (the size of the area targeted by the laser). This allows your provider to customize the treatment to your skin type, target areas, and goals.
Two modes—Static or Dynamic—allow your provider to choose the right frequency and energy level for your skin type, helping reduce sensitivity and improve results.

After a Primelase treatment, your skin may feel and look like you have a sunburn for up to 3 days. This can look like irritation, inflammation, swelling, and pigmentation changes in the treated area.Â
Side effects like these are usually mild and temporary. In the meantime, there are a few things you can do to help calm your skin down:
In the rare event that your skin burns or blisters, don’t hesitate to reach out to your provider.
A series of Primelase sessions will damage the hair follicles to the point that they become “inactive.”
It’s possible for major hormonal shifts to activate dormant follicles, so you may need touch-up treatments down the road—but you should never be as hairy as you once were.
