The Benefits of Lactic Acid in Goat Milk Soap

The Benefits of Lactic Acid in Goat Milk Soap

As most of us know, your skin is the largest on your body. It is consistently absorbing everything that touches it. That’s why we believe that feeding your skin with a quality soap is so important!

Why is goat milk soap so good for your skin? Goat milk contains Vitamins A, D, and B6, as well as minerals like selenium that are essential for maintaining healthy skin. Vitamin A, for example, is known to support skin health by promoting cell turnover and repair.

In addition to those vitamins and minerals, goat milk also contains lactic acid. It belongs to a classification of acids called “alpha hydroxy acids” or AHAs. These AHAs do wonders for your skin, making it smooth and radiant. Below are some of the reasons why you should be using soaps (like ours) with AHAs in them.

The Benefits of Lactic Acid


AHAs exfoliate the skin by loosening and removing the dead cells on the surface of your skin. This helps to reveal fresher, vibrant skin underneath those dead cells, improving the overall texture and tone of your skin.


One of the chemical properties of lactic acid is that it attracts water molecules. Scientists often use the term “hygroscopicity” to describe this tendency of a substance to absorb moisture from the atmosphere. When applied to your skin via goat milk soap, lactic acid increases the natural moisture content of the skin and helps it to retain water. This is especially helpful for people that suffer from dry or dehydrated skin.

Collagen Production

Using soaps with lactic acid can stimulate the production of collagen and elastin fibers in the skin. These fibers are essential for maintaining the elasticity and firmness of your skin. As you age, your skin will lose proteins which can lead to wrinkles and sagging. But by promoting collagen production via lactic acid, goat milk soap can improve the appearance of fine lines and wrinkles over time.

Brightening and Hyperpigmentation

If you suffer from hyperpigmentation or uneven skin tones, the lactic acid inside goat milk soap can help. By exfoliating the top layer of the skin where pigmented cells are concentrated, it promotes the growth of new skin cells that are more evenly pigmented.


Compared to other AHAs, lactic acid is mild and less likely to cause irrigation, redness, or peeling on your skin. This makes goat milk soap a great option for those with sensitive or easily irrigated skin.

Consult Your Dermatologist

While we’ve never seen any negative results from using our goat milk soap,  but it’s a good to always do the “patch test” when trying a new soap or product — especially if you have sensitive skin. If you want to know more about the benefits of using products containing lactic acid in your skin care routine, contact your dermatologist or local skin care professional to determine the best approach for your skin type.
