Very Effective in Healing and Clearing Skin [SEP] I cannot say enough good things about this Retinol Serum. I have tried several things from the Baebody line of products, and they have all been very high quality and very effective. I am a huge fan of Retinol and how it benefits the skin. I am at a crappy age where I still get breakouts, and I am starting to get wrinkles. I hate having the same gross skin as I did as a teenager. And I have tried everything! Prescription meds, prescription creams, ProActiv, micro-dermabrasion, chemical peels, etc,etc. Nothing seemed to help until I started using this Retinol Serum. Retinol is just a fancy word for Vitamin A and apparently me skin is in desperate need of it. It acts on DNA to promote healthy epidermal skin cells. It does a great job of moisturizing my skin, which helps with wrinkles. And it also does a great job of preventing breakouts. If I do break out because of hormones, it helps clear them up without drying out my skin. Sometimes it clears up my skin within a day or overnight. Vitamin A is a really potent antioxidant that protects your skin from free radicals, generates cell growth, and repairs damaged cells. Retinol belongs to a family called retinoids, and is one of the only substances that is small enough to penetrate the outer epidermal layer to the layer where collagen and elastin reside. It is really strong at first. It is really effective and it is tempting to want to use too much too often, but it can end up irritating the skin. I started using it every other day at first and then built up to using it every day. I also like to use a Vitamin C serum, but using Vitamin C and Retinol together tends to decrease their effectiveness. And sunlight decreased the effectiveness of Retinol, so I use the Vitaming C serum in the morning and the Retinol Serum at night. I let it work it's magic while I sleep. It has helped clear up my skin and help heal sun spots and acne scars. My only regret about it is that I didn't start using this years ago! I was able to try this Retinol Serum at a promotional discount for testing and reviewing purposes and in exchange for my honest and unbiased opinion.
