The surgeon told me that my dark circles are pigment related instead of Tear trough so fillers won't help.
I want to look into peels with dermaroller.
Any success using mild peels (TCA, lactic, kojic etc) for dark circles?
Also does dermaroller help the skin under the eyes become thicker and will it help the peels penetrate deeper??
Is retin-A the only thing that will THICKEN skin under eyes? if so whats the best retin-A ??
whats a great sunscreen product for face and body?? |

Retinol is not the same thing as Retin-A (a brand name for retinoic acid/tretinoin). Per an article I read:
Retinol and retinoic acid are related but distinctly different. Retinol and other forms of vitamin A, such as retinal and retinyl palmitate, do not have much direct effect on the skin. They first need to be converted by special enzymes into the active metabolite, retinoic acid. Only retinoic acid directly affects skin cells and helps reduce some signs of aging.
In theory, one should be able to apply retinol to the skin, wait till it gets converted to retinoic acid, and eventually get the known skin benefits of the latter. In reality, the conversion rate is low and varies greatly among individuals. Besides, when exposed to air either during storage or use, much retinol may get oxidized or degraded even before it can become availalbe for conversion to retinoic acid in the skin. As a result, significantly less people respond to retinol creams than to retinoic acid (tretinoin, Retin A), and the degree of response tends to be less too.
It is true that retinol products tend to have fewer side-effects than retinoic acid (tretinoin, Retin A). The reason is the same: lower biological activity of retinol due do slow conversion and, possibly, degradation |
