Learn more about WaterGlycolic Acid is arguably the most famous AHA with a ton of research to back up its benefits.
Its main role is to remove the top layer of dead skin cells, allowing newer skin cells to emerge.
Specifically, AHAs work by breaking down the structural "glue" holding the old skin cells in place. Getting rid of the old skin cells allows skin to regenerate newer skin cells in its place. A build up of dead skin cells can lead to tired and dull looking skin.
Due to this, glycolic acid helps with:
Fun fact: Glycolic acid increases skin hydration by playing a role in creating molecules that create hyaluronic acid naturally.
When starting glycolic Acid, it is normal to feel slight stinging.
The pH value and concentration of glycolic acid play a role in the effectiveness of the product. Concentrations between 5-20% glycolic acid have been shown to be effective in clinical studies.

In small amounts, sodium hydroxide is considered safe to use. However, large amounts may cause chemical burns due to its high alkaline.
Your skin has a natural pH and acid mantle. This acid mantle helps prevent harmful bacteria from breaking through. The acid mantle also helps keep your skin hydrated.
"Alkaline" refers to a high pH level. A low pH level would be considered acidic.

I can feel it working as I literally experience a slight prickly sensation on my skin. I believe it is helping my skin, as I’ve noticed that my pores have become less noticeable since I started using it in my routine. However, I would still look for an alternative that works but doesn't have that slight prickly feeling.

This is making me break out. I broke out in a huge nodule that was hard and red. Had to buy another product to treat that. Broke out in tiny white dots on forehead.
I really love this product. It made my skin silky soft and I see very less tiny bumps on my face after using this one.
