My Favorite Ingredients: Lactic Acid

What is lactic acid?

Well let us first address that lactic acid is different from Lactose. Lactose is a sugar found in milk, Lactic acid is produced from lactose through a process called fermentation. This fermentation process is commonly used in the production of yogurt, cheese, etc. Lactic acid is a compound that plays a crucial role in many different biological processes.

In the human body, during intense exercise or when oxygen levels are low, lactic acid is naturally produced as a byproduct from our muscles breaking down glucose to produce energy. Lactic acid is responsible for the burn and muscle fatigue you have most likely experienced during an intense workout. But lactic acid isn’t just a byproduct, it actually serves a purpose in the body beyond that. It can also be converted back into glucose in the liver providing an alternate energy source.

So how does this all relate to skincare?!

Well to be honest the connection absolutely fascinates me! We use lactic acid in skincare for its exfoliating and moisturizing properties. Lactic acid belongs to a family of acids called alpha-hydroxy acids or AHA’s. AHA’s gently exfoliate the outer layer of the skin by removing dead skin cells which prompts cellular turnover which is one of the best ways to improve the overall texture of the skin making it smoother, brighter and more radiant! Another great benefit of exfoliation is that it helps to unclog the pores and minimize the appearance of blackheads and acne.

One of the reasons that I LOVE lactic acid as an exfoliate is that it is particularly beneficial for individuals with dry or sensitive skin, as it is a more mild and hydrating acid as compared to other AHA’s!

As those of us who live here know, Colorado has an extremely dry and arid climate which can really wreck our skin and make it particularly hard to keep a healthy skin barrier in tact. Lactic acid attracts water to the skin, helping to keep it hydrated and improving natural barrier function. The hydrating properties of lactic acid make it a particularly beneficial ingredient for individuals with dry or dehydrated skin.

As always I recommend consulting with a licensed professional when using skincare products with acid’s to ensure the product is right for your skin. It is always a good idea to follow the instructions provided to you and start with lower concentrations to avoid any potential skin irritation.
