What Is The Ordinary Lactic Acid 5% & What Does It Do?

This 5% Lactic Acid is a mild superficial peeling formulation. Lactic Acid is an AHA (Alpha Hydroxy Acid) which exfoliates the top surface of the skin. Like the red peel, the AHA 30% + BHA 2% and Glycolic Acid, this also has the Tasmanian pepper-berry which is known to reduce signs of inflammation and sensitivity which can occur with exfoliation/use of acids. Once you have used the 5% Lactic Acid you could look at the 10% which is stronger. 

Lactic Acid 5% is great for even tone, textural irregularities, and fine lines. I personally love these Lactic Acids as they leave your skin feeling so smooth and soft.

How & When Do I Use Lactic Acid 5%?

Lactic Acid is a water-based product so if you have looked at the how-to layer The Ordinary, page you will know that water-based products are applied first and acids should be applied to cleansed, dry skin.

Add a couple of drops into the palm of your hands and apply to your face avoiding the eye area. Acids should really only be used in the evening because AHAs can make your skin sensitive to the sun. For more in-depth information about Lactic Acid including ingredients and precautions, please see The Ordinary website.

Which Products Conflict With Lactic Acid 5%?

  • Peptides including Copper Peptides
  • EUK 134
  • Niacinamide Powder
  • Other Acids, Retinol/Retinoids and Direct Vitamin Cs

This is the response from Deciem about Acids & Peptides.

Our rule against combining strong antioxidants only applies to our products containing copper peptides. We would not recommend combining direct acids with peptides due to the susceptibility of peptides to hydrolysis (which breaks the bonds between peptides, reducing their efficacy and making them into individual amino acids). At low pH, the peptides undergo processes such as deamidation (the removal of an amide group) and oxidation, which compromise the activity of the peptides.

Having said that, if you have previously combined peptides with acids and have not experienced any negative side effects or discoloration, you may continue to combine the two products as so as the combination does not pose any potential harm. Our recommendations are meant to serve as a preventative measure to avoid any incompatibility between those combinations and also because skin tolerance is subjective.
