Lactobionic Acid

October 06, 2020

What is lactobionic acid?

Lactobionic acid is a sugar acid and is part of the family of polyhydroxy acids. Lactobionic acid has similar effects to alphahydroxy acids such as glycolic acid but is associated with less sensitivity than AHAs. Lactobionic acid is used to treat photoaging, due to its large molecular size and slower penetration rate. Due to its powerful humectant and anti-ageing properties, it is widely used in skincare formulations.

Benefits of lactobionic acid

1. Gentle exfoliation

As lactobionic acid expedites cellular turnover, lactobionic acid can help refine skin texture and minimise the appearance of fine lines, wrinkles and enlarged pores, and promote a more luminous and even skin tone for all skin types. It also aids in diminishing scars and hyperpigmentation. It doesn’t penetrate the skin too deeply and exfoliates only the upper layers, which makes it gentle enough for sensitive skin.

2. Healthy hydration

Lactobionic acid is a powerful humectant that helps the skin to attract and retain moisture. It also encourages the production of elastin and collagen, which help skin to remain better hydrated.
3. Antioxidant protection

Lactobionic acid is an antioxidant that absorbs environmental stressors such as free radicals. A study found that lactobionic acid may also help to suppress matrix metalloproteinase (MMP) enzymatic activity, and therefore can help to protect against any further sun damage.

Is lactobionic acid suitable for my skin type?

Lactobionic acid is compatible with all skin types. It is particularly recommended for use on sensitive skin.

Can lactobionic acid be used alongside other products?

Lactobionic acid works well in combination with most other products, particularly with other acids. It is safe for use alongside many other key actives but should not be used alongside products containing retinol.

How often should I use lactobionic acid?

 You can use a product containing lactobionic acid once a day (after cleansing and before applying moisturiser). You should avoid using a retinol product directly afterwards.
