Kerstin Florian Intensive Renewal Crème 15% Glycolic Acid, Anti-Aging Corrective Face Cream Reduces Fine Lines and Wrinkles, With Vitamin C and Hyaluronic Acid (1.7 fl oz)

I use Retin A three times a week. I have been doing this for years with some breaks. It works like no other antiaging product. However, I like several other types of skincare products as well. I asked my dermatologist if it was OK to use Glycolic Acid with the Retin A and he said yes but on different days so as not to causes sensitivity. I have been using this Kerstin Florian Intensive Renewal Creme two to three times a week and it is effective. It doesn't sting at all even though my skin is prone to stinging from the retinol. It makes my face feel a bit tight but I always moisturize with a rich cream to offset dryness caused by these exfoliating products.This one is gentle. I didn't peel or flake but my skin looks glowy and firm when I wake up. The tube has a pump delivery system and I need a few small pumps for my face and going down a bit on my neck. The combination of Retin A, Kerstin Florian Intensive Renewal Creme, and Vitamin C serum is making my skin look so good. Too bad I can't go anywhere to show if it off due to covid but I feel better about my aging face when I look in the mirror when I take good care of my skin. This is a pricey product but it works well. I wish it were half the price because there isn't all that much product in the tube. I removed a star because the price is high and the concentration of GA is lower than with some other cheaper preparations. But it is a very good product, especially for those just starting to use glycolic acid.

I was introduced to this product by an esthetician, and usually I am skeptical about being 'sold' on products at a spa. But this product really delivers as promised. I haven't found a better bio-glycolic yet!

I've been using this product for 5+ years. Works great to achieve a beautiful glow. This product will cause your skin to dry out due to the salicylic acid found in the product. I use this in the evenings followed by a vitamin C serum with hyaluronic acid.

This comes packaged nicely in a nice outer product box. Inside, the tube has a pump, which is nice!The product itself feels creamy. It glides onto the skin easily and absorbs quickly. A little goes a long way, which is great because this is pretty expensive and I don’t ever want to run out! It doesn’t tingle or sting at all after applying. You leave it on the skin overnight so it can do it’s magic. When you wake up in the morning your skin will be softer, smoother, and glowier...a combo I love! I didn’t experience any redness or flaking that can often accompany a product like this. But, I don’t have sensitive skin, so if you do, you might want to do a patch test first. Do a patch test, see how your skin handles it. Even if you end up getting redness or flaking, that doesn’t mean you can’t use this. You just either need to get your skin used to it, or just use it for less time. If you feel like your skin is too sensitive or you like how it works on your skin but you’re getting some redness and/or flakiness that you don’t like, I’d recommend not leaving this on overnight. Directions say to just apply it and leave it on. But, if you’re experiencing redness or flakiness or you’re skin is extremely sensitive, you can apply it to your skin, leave it on for a bit (from a few minutes to a few hours, whatever you feel will work for your skin) and then rinse it off. You don’t have to leave it on overnight.I think this is a great product! It’s pretty darn pricey so I’m glad a little goes a long way! I feel like it’s gentle, but, again, I don’t have sensitive skin!

I love this product and use it once a week. My face feels so refreshed when I use it.

This is a very good product. It is not too strong, but sufficient to have effect on turning over cells.

Extremely strong!Fair warning to those with sensitive skin. I applied this at night after cleansing with no toner or other products. The next morning I woke up and was broken out pretty severely around my forehead.The product does almost burn while being applied as well so I have no doubt the product works but I personally can’t use it on my sensitive skin.

Product does what you expect
