Which laser skin treatment targets sebaceous glands?

Lasers and other light therapies work by different wavelengths of light being attracted to particular colours (chromophores) and transmitting their energy to the chromophore. The Laser Genesis wavelength is mainly attracted to the colour red, which in the skin usually means blood and blood vessels.  When little to no red chromophore is present, the wavelength transfers its energy in the form of heat to the dermis (the lower layer of the skin) and this initiates collagenesis, the formation of new collagen.

This increase in collagen can give better structural support which helps to minimise pore size, however this does not decrease the activity of sebaceous (oil) glands. Increased sebaceous gland activity is mainly driven by hormonal factors and may respond to the oral contraceptive pill. You may also have heard of Roaccutane which is a prescription drug used to reduce sebaceous gland activity. There are also topical products such as tretinoin (Vitamin A) creams that will assist in break-outs and oily skin. Speak to your dermal clinician and your doctor about these treatments.

The optimal laser in your situation is the use of a particular WAVELENGTH in a short pulse duration, carbon can be absorbed into the sebaceous gland. Another option is a non laser treatment with PDT using the 633 wavelength. See a dermatologist for a tailored treatment. All the best, Dr Davin Lim. Brisbane. Australia.
