Lactobionic acid (LA) is about to become your favorite skincare ingredient for smooth, radiant, clear, and plump skin. And that’s not an overstatement!

We’re full to the brim with alpha-hydroxy acids (AHAs) like glycolic acid and beta-hydroxy acids (BHAs) like salicylic acid. Similar to them, lactobionic acid is also a chemical exfoliant.

It works to remove the dead skin cells from the outermost layer of the skin, revealing smoother, brighter, and healthier skin. But it does this so much better and way gentler than your typical BHA or AHA.

So if you’ve been trying to exfoliate but your skin is sensitive, lactobionic acid is exactly what you’re looking for. Find below everything there’s to know about lactobionic acid for skin, how to use it, and the best products to try it.

What Is Lactobionic Acid?

Lactobionic acid is a type of polyhydroxy acid (PHA) and is used in skincare as a chemical exfoliant. To be more specific, lactobonic acid is a polyhydroxy bionic acid.

Other polyhydroxy acids you might be familiar with are gluconolactone and maltobionic acid, which are also used as exfoliating acids (1).

Due to its structure, lactobionic acid is among the gentlest chemical exfoliants available out there. This can be a curse for some, but a blessing if you’re the right person for it.

LA is not as fast-absorbing or deeply penetrating as other ingredients, such as glycolic acid, might be. It works on the surface level of the skin which is as gentle as it gets.

It removes dead skin cells at a slower rate, so it doesn’t irritate your skin. These less penetrative properties make it significantly preferable for people with sensitive skin, eczema, and rosacea.

Benefits of Lactobionic Acid For the Skin

Lactobionic Acid Skin Benefits

1. It exfoliates without irritation.

Exfoliants loosen the bond that holds the dead skin cells together. That’s how exfoliants accelerate skin turnover and improve skin texture and tone.

But this process can be irritating, especially if you already have sensitive skin. This irritation also increases the skin’s vulnerability to the sun, making it prone to sunburn.

Several studies show that lactobionic acid is the best acid when it comes to exfoliating the skin without irritating it (3). It’s suggested as an alternative to mainstream hydroxy acids.

For that reason, people with an already compromised skin barrier can highly benefit from LA’s gentle exfoliation (2). Since lactobionic acid doesn’t irritate your skin, it doesn’t make it any more prone to sunburn either.

2. It protects the skin.

UV exposure, aging, and skin inflammation stimulate certain enzymes in the skin. These enzymes are called Matrix Metalloproteinases (MMPs). It’s a mouthful, I know.

Too much activity in the MMPs department actually causes damage to the outer layer of the skin, the skin barrier, and collagen. This results in wrinkles and saggy skin.

It turns out, lactobionic acid prevents these enzymes from damaging collagen cells. What’s more preventative and anti-aging than protecting your existing collagen?

3. It has antioxidant properties.

A lesser-known fact about hydroxy acids is that some have antioxidant properties. For example, alpha-hydroxy acids such as citric acid and malic acid are antioxidants. Similarly, lactobionic is also an antioxidant (4).

Since oxidation and free radical damage from UV exposure are causes of aging skin, it’s suggested that lactobionic acid is majorly anti-aging because of its antioxidant properties.

4. It hydrates the skin.

Lactobionic acid is more humectant than regular humectants found in our moisturizers. You must have heard about glycerin or sorbitol from your favorite moisturizer. Well, lactobionic acid can attract and retain water better than those!

When drying down, it forms a gel layer on the skin thanks to its strong ability to retain water (5). This is a dream come true for dry skin that also needs exfoliation sans the stripping.

5. It gives you clear skin.

The anti-aging benefits of lactobionic acid were tested on 31 females who were instructed to use a face cream infused with 8% lactobionic acid. The women used this cream twice a day for 12 weeks.

The results are jaw-dropping on so many levels like improved skin thickness, wrinkles, pore size, and firmness. But the most impressive result is a 100% increase in skin clarity and radiance and a 70% improvement in rough skin texture (6).

6. It plumps up the skin.

As lactobionic acid is a strong humectant, it has amazing plumping effects on the skin. Because it’s able to hold and retain moisture, your skin looks plumper for longer compared to other humectants.

This is also handy when you have wrinkles because plump skin reduces the visibility of wrinkles. Lactobionic acid keeps the skin hydrated and gives it a fresh and radiant look.

Side Effects of Lactobionic Acid For the Skin

Overall, lactobionic acid has no prominent side effects such as irritation or sensitivity which are usually associated with chemical exfoliants.

However, there’s always the potential for irritation especially if you have very sensitive skin. But this is usually the result of using a lactobionic acid product that also contains other active ingredients.

If you’re using lactobionic acid and your skin is irritated, check to see what other active ingredients the product has as those may be the culprit.
