HG AHA

This was my first product from The Ordinary and it turned me into a forever fan. I use the 10% version of the Lactic Acid and alternate nights with the 2% Retinoid. The results have been amazing. I've wasted so much money with little success trying to get rid of the damage and sunspots from my youthful sunworshipping/tanning bed addiction. This is very effective and under $10. I'm thrilled with the soft feel and brighter appearance of my skin in the morning. Sunspots are noticeably lighter. Highly recommend this, but if you have sensitive skin start with 5% 2-3 times a week and work your way up.

Stronger than the Retinol I've been using.

I have been using this just once a week so far because I'm also using the 2% Retinoid product. This one has made my skin react more but it's still an excellent product. It makes my skin so soft the next morning and I can see a real difference, after using the products in this line.

great when on a budget

This is basically a cheaper version of sunday riley good genes. it works great if you like a light lactic. the 10% is a bit stronger than sunday riley, but very effective

I use this in conjunction with The Ordinary 2% Retinol every other night (alternating). It leaves my skin feeling so soft and has already lightened some scaring I had from previous (teenage) acne.
