I am a female in her early 20s who suffers from sunken eyes (eye hollowing) and mild milia. Because I do not want to go to into surgeries and use fillers, I was wondering if Retin-A is a good solution to increase collagen and boost volume under the eyes? I heard that using Renova and Lumiere cream in combination helps - is it true? If not, what are the best vitamin A derivative brand to use and in combination with which creams? Is there a better laser that boosts collagen (e.g. Active Fx?)?
