Replenix Glycolic Acid 20% Resurfacing Cream, Hydrating & Lightweight Medical-Grade Exfoliating Face Moisturizer for Skin Discoloration (1.7 oz)

Update: I just received my second jar and noticed that not only is the jar much larger (same volume of product though) but it has an added ingredient. This product now contains Co-Q10. If you have purchased before I feel like it is good to note the new add-in.Quick Review of THIS product:I love the 20% concentration. I have used 5% and 10% creams and 40% and 70% peels. The 20% glycolic acid cream is perfect for my aging skin now that I'm very used to having acids on my skin all the time. This cream doesn't burn as much as the 10% and that may be due to the added antioxidants (even though that doesn't make sense). I wear this cream almost 24/7 now because it isn't drying like previous creams/peels and it doesn't interfere with my makeup. I forsee using this cream for a long time and my skin is already greatly improved. My skin texture is like porcelain. Love it!My complete journey with glycolic acid creams/peels:Okay, I started using various acids on my face several years ago. First I tried lactic acid and realized I'm allergic. Then I found a glycolic/salicylic combo that turned me into an acid fanatic (okay that sounds bad). I soon moved on to Skin Obsession's 40% glycolic acid peel liquid. I loved it but it made my skin really dry for days and older looking for about a week due to the dryness so I couldn't use it regularly and using it around my eyes where I had fine lines I wanted to knock down before they turned into deep wrinkles, was scary to say the least.Then I discovered Reviva Labs 5% glycolic acid cream at Ulta. It was mild enough to use every day and it really improved my adult acne. My breakouts were less frequent and the zits I did get healed much faster. I soon moved up to the Reviva Labs 10% cream when my skin got used to the 5%. The 10% took my skin to another level of smoothness and the dark marks leftover from a lifetime of acne were starting to fade. I used the 10% cream and the occasional 40% peel regularly for nearly 2 years. My breakouts were nearly a thing of the past and I really only got hormonal acne. I'm pretty sure I haven't had a gargantuan zit or cystic zit since I started using the 10%.I then started mixing my own percentages of ASDM Beverly Hills 70% glycolic acid peel with water to get about 50-60% acid peels. The ASDM is actually far less drying than the 40% even though it is a higher percentage. Not sure why but maybe my skin is just really used to acid peels now.About two months ago I decided my skin was in need of something stronger to really get rid of my deep discolorations, pits and uneven aging skin. I went to Amazon again and searched for something that looked promising. There were a lot of 15% creams but I didn't want to increase a measly 5%. I wanted 20% or higher. And then it happened. I came across Topix Pharm Glycolix Elite Cream with 20% glycolic acid AND antioxidants. I noticed a difference in how my skin felt after my first overnight application. I woke up with smoother, more hydrated skin. My skin seemed to be more clarified and I debated whether I even needed makeup (I did, I still wore it and I still am... cream isn't magic). I have now been using it for almost 2 weeks and I am sooooo happy with my purchase.My skin is very smooth now so when I put on even a little bit of my makeup, I look flawless. When I removed the makeup, my skin has more of a plumped up glow to it. I don't look as sallow as I used to. This cream doesn't burn AT ALL but that may be due to my being use to the acid. It does sting for a few seconds if I apply it right after I do my thrice weekly face scrub (my favorite time to apply). Overall, this product is definitely going to be in my beauty rotation for a while.New update in Nov 2018 after years of using acid treatments:I am still using this 20% cream but now only about 2 times a week. Why? Because my skin is awesome now. I am not at all embarrassed by my skin texture, spots or pore size. I can leave my house and run errands or workout without feeling like I look gross. This cream keeps my fine lines away and helps with dryness so I do still use it but not for the same desperate reasons as before. This cream and all my acid treatments have really saved me from a lifetime of skin issues. I now get to focus on moisture more and I have stopped doing scrubs all together as they are more abrasive than this cream so I let this cream do the exfoliating.
