Glycolic acid is a recent addition to my skincare routine. It is quite effective in providing me regular chemical exfoliation and helps me deal with my acne and pigmentation.
If you are looking for an easily available glycolic acid product that you can find at your nearest medical store, turn to Glyco 6.
Glyco 6 is a cream product that contains 6% glycolic acid. I use this product on alternate nights. I apply a but sized amount of this cream all over my face after cleansing with Cetaphil and toning with rose water. I follow this up with my usual moisturizer, Cetaphil Moisturizing Lotion. Glyco 6 has a strong smell, so those with sensitive noses must be careful. The cream absorbs very easily into my skin and the smell dissipates after some time. Don't expect immediate results with this product. After using it for about 5 months on alternate nights, I've found that my acne heals faster and that my skin looks brighter and more evened out. Be careful to not apply this product too close to sensitive areas like around your eyes and near your mouth. It is very easy to go overboard with chemical exfoliating products, so listen to what your skin tells you. If you experience any redness or irritation, discontinue the use of this cream. Also, you might experience slight tingling initially, as it is seen while using chemical exfoliants.

Another word of caution, it is essential go use sunscreen during the day while using Glyco 6, because the continuous exfoliation makes your skin sensitive to the sunlight. Using sunscreen is non excusable. As long as you prevent going overboard with this product and keep using sunscreen during the day, you'll notice a marked improvement in your acne and pigmentation. There is a stronger, double strength version of this cream available on the market, containing 12% glycolic acid, but I will review it later!
For now, I will definitely repurchase Glyco 6. I have already used up 5 tubes of this product. Give it a shot!
