Lactobionic Acid: Here's Everything You Need to Know About It

What exactly is lactobionic acid?

To put it simply, Lactobionic acid is the oxidized form of lactose that is derived from milk. Lactobionic acid is a polyhydroxy acid (also known as aPHA) and is an exfoliator, but one that is a gentler Alternative To glycolic and salicylic acid. Because ‘Lactobionic’ is a larger molecule than glycolic acid, it will not penetrate the skin as well, therefore, it is considered less strong resulting in it being less irritating on the skin.

Lactobionic acid is similar, but not quite the same thing. It, too, is derived from the lactose found in dairy products. However, lactobionic acid is a polyhydroxy acid (PHA). It also has exfoliating properties but is gentler on the skin than lactic acid. It's also lighter than glycolic acid, as lactobionic acid has a larger molecule size, which means it cannot readily penetrate the skin barrier. Instead, it actually strengthens it.

What are PHAs?

PHAs or polyhydroxy acids are known as the “second generation of AHAs". PHAs are different from AHAs since they are larger molecules and don't penetrate as deep into the skin. Thus, they cause  less irrtation but still provide the same benefits as AHAs.

Can Lactobionic Acid be used with other ingredients?

Lactobionic Acid shouldn't be used in conjunction with retinol, the reason for this is because both ingredients work to increase cell turnover. Therefore, because they are doing a similar job if they were to both be used together at the same time it may lead to skin irritation, redness, flakiness, and dehydration and could ultimately compromise the skin's protective barrier - doing more harm than good! 

The many benefits of lactobionic acid for your skin

Lactobionic acid is incredibly beneficial for your skin. Not only does it strengthen the skin barrier, but it's also a great choice for people who are prone to skin irritation and sensitivity. In addition, although it's an exfoliator, it can be safely used daily. Some of the main benefits of incorporating lactobionic acid into your daily skincare routine include the following:

♦ Gentle exfoliation – Lactobionic acid doesn't penetrate deep into the skin, and therefore it won't provide dramatic exfoliation. However, since it's safe enough to use daily, you'll see significant improvements with continued use. As an exfoliator, lactobionic acid works by gently breaking down the bonds between the surface layer of skin cells. It allows the old skin cells to be sloughed off and your new, younger, vibrant-looking skin to shine.

♦ Humectant – Lactobionic acid is seriously hydrating. It draws moisture into your skin to keep it well-hydrated and plumper.

♦ Anti-aging properties – Lactobionic acid fights the signs of aging. It improves elasticity and guards against fine lines and wrinkles by increasing the production of collagen.

♦ Skin brightening – Fed up with pesky under-eye dark circles and areas of hyperpigmentation? Lactobionic acid can help with that. When used consistently, it'll help fade those dark spots.

♦ Sun protectant – Lactobionic acid also has antioxidant properties. This means it can offer extra protection against those harmful UV rays. However, please note that it's not a substitute for sunscreen.

How can you incorporate Lactobionic Acid into your skincare routine?

You can find Lactobionic Acid within a number of skincare products. From scrubs, serums, peels and masks. The first place to start will be to decide which format you would like to use and add (or even replace an existing product with) into your skincare routine.  Lactobionic acid is generally a good follow on from cleansing, so look for products to use following this step in your routine. If you are someone who has particularly sensitive skin you should look to gradually introduce this new ingredient, starting with once a week, then (as long as your skin is not reacting) building it up to three times a week and eventually daily.  Over time you would be able to reap the benefits of improved tone and elasticity from this ultimate glow-booster!
