Why Lactic Acid is our Favorite Scary Word Ingredient


In the world of skincare, when people hear the word ‘acid', it’s usually associated with getting a chemical peel at a spa. There are many types of acids that are used in skin care. If you’ve ever had a professional chemical peel, you’ve probably been treated with either a high percentage of a alpha hydroxy acid, a glycolic or a even a trichloroacetic acid. These treatments are higher percentage acids that are applied to your skin to chemically exfoliate your skin and reveal new, healthy cells. Depending on the type of peel, you may have some downtime or at a minimum, some redness and sun sensitivity, as well as some expense.

Our favorite acid is lactic acid. It’s an Alpha Hydroxy Acid (AHA) that is safe and gentle enough to use every day, not just once in a while for a special treatment. It is a chemical exfoliant that breaks down and releases dead skin cells to reveal healthy, glowing skin.

Why We Love It

  • It’s well tolerated by sensitive, mature or acne-prone skin;
  • It promotes cell turnover and rejuvenation;
  • It helps to improve pigmentation and discoloration issues;
  • It works to build and protect your skin’s natural barrier layer and improve hydration;
  • It prevents clogged pores and congestion,
  • Skin looks younger, fresher and plumper, brighter, softer and smoother;
  • It improves skin texture and diminishes the appearance of wrinkles;
  • It’s derived from natural ingredients that are found in many foods.

Formulation is Key

When you have a professional chemical peel, you’re getting a clinical treatment that includes products to prepare your skin for the acid application as well as ingredients that will nourish and protect your skin after the acid is removed. For daily, at home use, the formulation is a very important consideration. We recommend a ‘low and slow’ approach to using products that contain lactic acid which means using a low percentage of lactic acid on a daily, long term basis with a formulation that has nurturing ingredients that support each other in an optimal pH level base.

The highest percentage of lactic acid content can be found in our Retexturizing Night Cream which has a 9% lactic acid in the formulation (the highest you can buy without a prescription). For more sensitive skin, Daily Brightening Tonic and Moisture Renew Mask are also formulated with this favored ingredient!

PRO TIP: Since lactic acid encourages cellular turnover, it's a great ingredient to use for ingrown hairs or to gently exfoliate bumpy arms and legs!

A Word About Sun Sensitivity

As with all types of acids, since you’re stimulating cellular turnover, your young cells are susceptible to sun sensitivity and we always recommend using SPF, even if it’s cloudy!
