Lactic Acid vs. Glycolic Acid: Which is Best for My Skin?

Lactic acid vs. glycolic acid: how to choose? When it comes to selecting the best products for your particular skin concerns and needs, lactic acid and glycolic acid are two well-liked skincare chemicals, and for good reason. Continue reading to learn more about lactic acid, glycolic acid, and how to choose the right one for your skin.

Lactic acid?

Lactose, a carbohydrate found naturally in milk, is fermented to create lactic acid, a chemical exfoliator. Lactic Acid has been a frequent and well-liked ingredient in many skincare products and is primarily offered over-the-counter or in prescription-strength formulations.

The Alpha Hydroxy Acid (AHA) family, which also comprises Mandelic and Glycolic Acids, includes Lactic Acid as a member. AHAs are chemical substances that dissolve in water and have exceptional skin-benefitting effects when added to cosmetic formulations.

AHAs are good because they are made of molecules that are small enough for your skin to easily absorb. They are natural acids that can be obtained from plants. As a result, AHAs can significantly improve the appearance of fine lines and wrinkles, smooth out rough skin texture, and generally make your skin look better and more youthful.

Another advantage that lactic acid has over other AHAs is that it keeps the skin hydrated in addition to enhancing the skin's overall appearance.

Glycolic acid?

One example of an Alpha Hydroxy Acid (AHA) that is water soluble is glycolic acid, which is produced from sugar cane. One of the most widely used AHAs used in skincare solutions is glycolic acid, which may provide a number of advantages.

Lactic acid vs. glycolic acid 

Lactic acid and glycolic acid differ from one another at the molecular level. I'm not a cosmetic chemist, but one approach to deciding which one is best for you is to grasp their distinctions. Due to the tiny size of its molecules, glycolic acid penetrates the skin more deeply, strengthening it. Because its molecules are larger, lactic acid is gentler.

The effects of glycolic and lactic acids on the skin vary as well. For a clearer, brighter, and smoother complexion, they both exfoliate, but that's not all. It's excellent news for any anti-aging concerns since glycolic acid encourages the formation of hyaluronic acid, collagen, and elastin. Lactic acid is crucial for optimal barrier function since it also increases collagen, one of the skin's natural moisturizing components.

• Glycolic acid is best for sun damaged skin

Lactic and glycolic acids are both beneficial for dry skin. However, glycolic acid goes above and beyond if your skin also has UV damage. And not just because it's the smallest member of the AHA family, which allows it to operate more quickly and deeply into your skin.

Because it increases collagen formation, glycolic acid has the superpower to keep your skin firm for a longer period of time. This is why it works so well to prevent aging symptoms.

• Lactic acid is best for sensitive skin

Lactic acid has advantages. particularly if you have delicate skin. The most gentle AHA in the family is lactic acid. When exposed to glycolic acid, sensitive skin frequently erupts and becomes irritated, although lactic acid is completely tolerated by it. Additionally, it is more moisturizing, so you might want to try this one if your skin is extremely dry.

Which acid is better overall?

If you think about lactic acid vs. glycolic acid, you might be wondering which one is better overall. The answer depends on how sensitive your skin is and how quickly you want to see results from your skincare regimen.

It's crucial to keep in mind that glycolic acid has a low molecular weight, which allows it to pass through your skin's protective layer and perform miracles from the inside out. Glycolic Acid may therefore result in speedier outcomes. However, glycolic acid may have a higher propensity to irritate delicate skin and increase sun sensitivity. If you experience tingling, dryness, peeling, or even burning, we advise stopping use and getting advice from your dermatologist.

Glycolic Acid is frequently recommended for uneven skin texture since it may penetrate deeper into the skin layer and may be better tolerated by normal to oily skin types. On the other hand, lactic acid is a milder exfoliator that can be perfect for dry or sensitive skin. It is less likely to irritate skin because of its larger molecular weight and hydrating properties.

Applying a new skincare product to your face after conducting a patch test to ensure there are no adverse reactions is always a good idea. We advise beginning slowly with lesser concentrations of each new product or component and then working your way up to more potent items.
