Should Yag be used on me when I have light skin tone?

Dear Suzanne:If you have fine hairs, GentleLase will be more effective than diode or NdYag. Your physician was probably concerned that you may be a little tan, but this becomes a problem with any skin type and any laser that removes hair, so using the Yag would not necessarily be safer. Your doctor will know right away if the treatment is likely to be effective, because the hairs in the treated area will frizz up as the laser light is delivered.If you are a little tan, properly formulated topical creams containing retinol, retinoic acid, tazarotene, glycolic acid, vitamin C, and hydroquinone can fairly quickly bring your normal skin tone back. You could then proceed with the GentleLase treatments, and to prevent tanning during the summer months use a sunscreen with micronized zinc oxide or mexoryl, and apply a green tea or vitamin C cream (properly formulated!) every few days, so that you can will be able to continue the treatments.

I agree with the choice of your dermatologist.  Based on your skin type and tan the Gentle Yag was the exact correct choice for you.  Perhaps if the hair did not fall out she can go up stronger next time.  When it is your face you have to be extremely cautious.  Always go to a board certified dermatologist for the best results.

Using Yag is a conservative and safe approach to hair removal. Treating your skin after sun exposure is tricky, since it can pick up some of the laser energy. Yag is safe even in darker skin but is not quite as effective as other wavelengths such as the Alexandrite. Once you are safely free of any sun exposure, perhaps it could be safe to use another laser that could be more effective.
