Hi C.---I would like to suggest that you start your skin care regimen from the inside out...with your diet. I've been studying wellness and nutrition for several years now, taking classes from a Naturopath who has her PhD in Nutrition as well as from many prevention minded physicians. We've actually talked about studies on skincare, and, the more fruit and vegetables that you eat (it is recommended that we eat 10+ servings each day), the healthier EVERY cell in your body will be, and that includes the skin, our largest organ.
Here is a link to an article by an expert we've recently worked with:

If you can't, won't or don't get the recommended servings of fruits and veggies every day, there is a research driven product available that is made of 15 juiced and dehydrated juice powders. Those that have skin issues report incredible changes in a short period of time. Everyone has this incredibly healthy glow.
What I am learning is that unless we grow our own food that we eat every day, we are likely deficient in nutrients...food is not vine-ripened so that is withstands long distance shipping, is starts to deteriorate as soon as it's picked, the growing cycle is accelerated in order to get more crops out of the field and natural crop rotations do not occur any longer, resulting in soil that is depleted of potential nutrients. But vitamins do NOT give the body what it needs compared to whole food. In any case, strive to eat even more fruits and veggies...mostly fruits and veggies, and you should see changes in your skin, as well as hair, nails, immune system function, energy levels, and weigh normalization.
Anyway, sorry about being a bit off topic. If I can be of any additional assistance, please let me know. It is my honor to help. Be well, D.
