I had very tired looking skin with dark circles and uneven skin tone before deciding to start using any anti aging products. I decided to add this glycolic acid to my routine alternating between it and a retinol cream with using more nights Replenix . I didn’t retouch anything in the photo. I am in my 50’s and feel Routine10 has helped in my fight to looking younger and rested.

I love this cream. I use it under my night moisturizer. I used to use the glycolic acid pads once a week. Now I use the cream every day except the day I do my microderm abrasion at home. One piece of advice: when you use glycolic acid, you want to start with a .5 and work up to the 20 percent if you have never used it before and also, don't put it on your eye area.

It does the work. It may be to strong for the face. I mostly used in the arms to discolor areas affected by keratosis and it did wonders.

20% Glycolic Acid is a strong acid so if you’ve never used a GA before start off slowly. The first night I applied this acid I felt a little sting/tingle so I knew it was working. I was trying to fade some old acne marks and shrink some pores. Next morning...my face looked so good. Barely any old marks, in fact they had faded so much I had to get up close to see where they used to be. My pores were teeny tiny. This Glycolic Acid is the best I have found and the price is good too. I highly recommend and I am onto my second jar.

I had never used anything of this strength before, so the initial, mild stinging on certain areas of my face was new to me. But boy if it didn't help get rid of old, dry skin. I have a low thyroid which causes dry skin and my skin to turn over and renew even slower than my 50 years would already have it turn over. But this has really helped rejuvenate my skin. I started noticing the improvement within 3-4 uses (using it about 2x week).

This cream is awesome and very effective at treating so many skin issues. My hyperpigmentation is almost gone and skin is finally glowing. I love using this with vitamin c serum and the ordinary vitamin c 23% suspension. It's is very potent so be careful and don't burn your faces off! Highly recommended!

I hit the 50s and decided it was time to take the condition of my skin seriously. I've been using this for about 3? 4? weeks and like what I'm seeing. After a week or two I noticed a definite difference in skin tone and pore size - both for the better. Slight irritation the first couple of time I applied it but now use daily.

I'm a 60 year old women with medium complexion. I had used Routine10 for many years that I got at my dermatologist office but the cost was so high and it lasted such a short time that I started researching other products. I tried several others but non worked to my satisfaction or complexion, then I ordered Glycolix 20% and from the first use I realized I had found a very promising product. Upon my first application I felt my skin tingling and turn pinkish "good sign" but when I woke my skin was glowing!!! A little goes a long, long way and my pores have diminished, my skin looks polished and at "60" I go without make-up and my skin is beautiful. I even got my husband using the product, he is light complexion so because the product is 20% he uses it twice per week and is skin is AMAZING! As a women that has spent a lot of $$ on my skin, I strongly recommend this product without hesitation! Good Luck!

I wasn’t sure if this is safe to use. It did have the plastic sealer on it. I’m guessing maybe the acid is reacting with something they sealed it with but I don’t know. Also, the container is smaller than I expected so I’m not sure it’s a great deal for $10. However, I’ve been using this for many months now and even finished the jar. I mixed it in my hand with Glycolic moisturizer and it worked very well. I noticed though that in the summer, which is humid here, that when I sweat it tended to get on my neck and irritated it terribly. So I ordered the 15% last time I reordered even though it’s winter. I think it’s much better for me because I have dry skin. Also, I’m able to use it without mixing it with the moisturizer. And I’m hoping will be better in the summer months. Very happy with this product as it makes my skin smooth and shiny. I’m a licensed cosmetologist and know about skin care so I feel very confident with using this. I use it every day unless my skin gets overly dry then I skip a day or two. I also use Retin A at night mixed with my moisturizer in even amounts.
