Lactic Acid: Is It Safe In Skincare?

Lactic Acid: Is It Safe In Skincare?

As we become more are of ingredients in our skincare, we can often start avoiding any ingredient that has specific wording in it. Words like "sulfate" and "paraben" and of course the red flag goes up when we see just letters followed by numbers- is it a chemical!?

But what about acids?  Well, you 'll be happy to know that not all acids are bad, and they are NOT all created equal in skincare. In fact, lactic acid can be found in our Flawless Facial Aloe-Papaya Moringa Oil Facial Moisturizer! So, let's talk about Lactic acid:

So here are the main things you want to know about Lactic Acid:

  1. Lactic acid is a natural acid derived from milk, fruit, vegetables and other plants. It’s found in over-the-counter skin care products used for anti-aging and is also used in chemical peels.
  2. Lactic acid is one of the most popular alpha hydroxy acids (AHAs) in skin care today.
  3. Lactic acid is a natural humectant which occurs naturally in the skin, and because of this, it is able to pull moisture from the air and hold it in the skin. Lactic acid is less irritating and more moisturizing than the Glycolic, and the Lactic can be used at a slightly higher concentration because it is non-irritating.

  2. Becuase it is a skin exfoliant, high amounts of it in any product (including natural peels) can cause the skin to be susceptible to sun damage. So use caution with AHA peels or products with Lactic acid listed as the main ingredient. 
  3. If you do choose to use an AHA peel with lactic acid (or any AHA peel for that matter) make sure you use an SPF protector like our Melan-In Skin Nourishing Serum+ SPF to protect the skin's sensitive layers. With spring and summer around the corner, I URGE YOU to invest in a good SPF!
  4. As I stated before, Lactic acid can be found in dairy, so if you are using yogurt DIY masks at home or with your 

 So, there you have it...a good acid ingredient in your skincare. I will be bringing you more in-depth ingredient blogs this spring, including introducing you to a few more friendly acids! Remember, research is essential in skin care. Skincare doesn't have to be scary if you read your labels and stay informed.
