Question:
Hi, I was wondering if laser that is used for hair reduction also able to help with pigmentation? I am specifically asking in relation to the underarm.
If one has dark underarms, or a condition such as Acanthosis nigrican, which laser can work, or is chemical peel also viable? This is with a person skin tone to be olive-dark.
Another question is that what treatments are there for acne scarring on the back that is covering a large portion, and the price?
THANK YOU!
Answer:
We generally don’t use the lasers for hair removal to help with Acanthosis Nigricans.
We often recommend using a lightening agent such as Kligmans formula for Acanthosis Nigricans. Combining dexamethasone, hydroquinone (a skin lightener) and tretinoin (a form of Vitamin A), it is able to achieve optimal results and lighten the pigmentation.
Kligmans formula needs to be prescribed by a doctor after consultation.
For back acne scarring, you can look at treatments such as Fraxel laser or skin needling
