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)that exfoliates the skin’s top surface. Like the red peel, the AHA 30% + BHA 2% and Glycolic Acis also has the Tasmanian pepper-berry, known to reduce signs of inflammation and sensitivity,y which can occur with exfoliation/use of acids. Once you have used the 5% Lactic Acid, you could look at the 10%, which is more robust. 

Lactic Acid 5% is great for even tone, textural irregularities, and fine lines. I love these Lactic Acids as they leave your skin 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 followed by your serums.

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

Which products should I not mix with Lactic Acid 5%?

See the chart above for all the products you should not mix with Lactic Acid.

Why can I not use Acids and Peptides in the same routine?

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 discolouration, you may continue to combine the two products so that the combination does not pose any potential harm. Our recommendations are meant to serve as a preventative measure to avoid incompatibility between those combinations because skin tolerance is subjective.

How To Layer The Ordinary Lactic Acid 5%

How many products you use in your routine is up to you, but The Ordinary recommends using no more than 3 serums. Some people like a quick,k simple routine, and some people like to use more products. Here are some examples of how to layer The Ordinary Lactic Acid.

JMS says:  Immediately broke my skin out and caused irritation. It’s not for my skin, but I’d love to hear some recommendations for a different exfoliant that might work better.

JH says: I absolutely love Lactic Acid 10%! I don’t know how people can get irritation with this. I have rosacea and had no bad reaction at all.

MR says:  1000% love The Ordinary Lactic Acid, and I think it has made the biggest difference on my skin.

KT says:  I am on my second bottle and will continue purchasing! After trying Sunday Riley Good Genes, I figured out that my skin loves Lactic Acid. But I don’t love that price tag. The Ordinary Lactic Acid 10% is priced perfectly and does exactly what I need it to do. I get a nice glow, and my skin feels great.

MMC says:  This is one of my must-have Ordinary products, and I always keep a new bottle stocked so I don’t run out. I alternate this every other night with a retinoid. It beautifully removes any flaking/peeling skin from the retinoid and leaves my skin smooth and glowing.

GB says It made me red and irritated with big red spots after using it.
