How glycolic acid works

  • Glycolic acid has the smallest molecule of all acids – only 1 micron – 1,000 times smaller than the ball of a ball pen
  • It penetrates deep through multiple layers of dead skin cells and helps get rid of them
  • So new, better looking skin shows on the surface of your face

I loved it

This product helps a lot with my stubborn dark spot . Ingredients are clean and simple . I will continue to use it . Highly recommended.


My skin has never looked better. This is no gimmick, it dies EXACTLY what it says it's will do. The tingling goes away immediately for my skin. I always feel so refreshed after applying. Hope you enjoy as much as I do!

Glycolic Acid

I have been using the glycolic acid every day for early a month. My sun . Spots are beginning to fade so I will continue to see if they will go away completely


So far I like it. Just used a few times. Trying to work my way up to using more than twice a week. I can feel it working. Time will tell if my skins texture and pigment issues will be improved. I’m hopeful!

Hi love this product!

I definitely see a huge difference in my dark spots and the price is unbelievable! I’ve tried another brand of product that was very expensive and it made my dark spots worse

This stuff is amazing!

I love all of the Open Formula products I have tried, but this one might be the favorite! It makes my skin so smooth and soft and is helping to lighten some pesky sun damage on my face. I love this and look forward to using it every week. You should try it, you won’t be disappointed!

So far so good

I haven’t been using very long but my skin is brighter. I’ll be trying more products. Thank you

Real Deal! Skin Changer!

I wish I would have discovered this product in my 20’s and 30’s! I could feel smoother skin after just two uses. It has been three months and my skin is smooth and clear. My dark spots are fading and a hard white bump on my jaw line has gone away! I only need SPF and mineral powder foundation now. In the past I had struggled to cover my breakouts with heavy liquid makeup. 💕 Skin Changer!

Spots begone

I’ve used this product along with many of there other products. I have a lot of sun damage and it is barely noticeable now. It’s not irritating and feels really nice on. It is priced better than similar products that I’ve tried and much more effective. Highly recommend it.

Works as it's supposed to

This product works great! If you've never tried it before, don't expect your skin to come off in sheets. Instead, it gently peels and encourages cell turnover. Apply a small amount to medical gauze, quickly swipe over skin, set timer for one minute, and then wash. You want to start off with the short time and build up as your skin builds up tolerance to avoid too much irritation.
SPF is a must when using this or else your sensitive skin will darken, negating any progress you may have.
It works as it's supposed to, just be patient
