This skincare tool is called a DermLite.This is the same equipment that is used by dermatologists to more closely inspect a suspicious skin lesion.
I use it during a skin analysis to determine if pigmentation is
epidermal or dermal. Knowing where the pigment is within the skin layers suggests
treatment options. Sometimes I will look at a lesion and will recommend the client
see her dermatologist or primary care physician for further analysis. I have had
clients tell me later that the lesion I was looking at was cancerous and was
treated/removed by the doctor. I also use the DermLite to determine if I am able to
treat a lesion or if the client needs to see a doctor.
