Anything new for brown spots on dorsal hands and face?

IPL. They turn black and fall off. Works great. (Intense Pulsed Light)

Acanthosis nigricans. Supposed to be due to hyperinsulinemia - which is due to insulin resistance. I have seen very few patients get rid of them by improving their insulin sensitivity

Brown spots do not have the same etiology or histology. Sometimes IPL, laser (Q-switched 532nm, 694 nm), fractionated resurfacing, hydroquinones, sometimes a mix, sometimes nothing works. Avoiding further sun exposure is pretty much (almost always) an element in the reduction and elimination of brown spots.

I have a question. I recently noticed some kind of a mole under my tongue. Should anything be done about it? It's approximately 3mm.

I've heard some doctors use liquid nitrogen to freeze and kill brown spots. Maybe that can help Ella? What is the name of that procedure?

RESPONSE TO LANDO:
Acanthosis Nigricans is a totally different thing and has nothing to do with the lentigenes on the dorsum of hands.

Have you noticed skin changes (color, size, shape)? Yes? Biopsy first. Melanoma is sneaky.

Candela eMatrix and Gentle Max Laser both work great for removingthe age/brown spots on hands and chest.

Photofacial remedies, skin treatment, also referred to as IPL, Extreme Pulsed Gentle Abbreviation, work well, no down time, safe means of removing pigment, or dark brown spots as well as broken arteries or pores and skin excess face.

We are currently using Laser360. It s a resurfacing and rejuvenating treatment. It is recommended for discolorations, as well as fine lines and wrinkles. The only downside is that you will experience reddish skin, flaking and itching within 48 hours post treatment. Full recovery is expected in 5-7 days.

I recommend using a facial cream that contains hydroquinone. This has skin lightening properties that will help get rid of brown spots on your face. In extreme cases, I recommend a cream with add'l ingredients such as cortisone and tretinoine. If none of these helps, you should resort to chemical peels/ laser. Consult your derm.
