Whether you’re looking to revamp dull skin, minimize fine lines look, enhance radiance, or lighten dark patches, the best lactic acid serums can help you out. Because lactic acid is the gentlest alpha-hydroxy acid (AHA), it can be used by everyone, sensitive skin included. It provides mild exfoliation that, over time, reveals luminous skin, an evener tone, and a smoother complexion.

Before we go to the good bit, here’s some theory for the uninitiated about what lactic acid actually does.

What is lactic acid?

Like other AHAs, lactic acid’s main role is to increase cell turnover and slough off dead cells from the outer skin layer, making room for new cells. As healthy cells replace old ones, skin becomes thicker, firmer, and brighter. But what makes lactic acid stand out from the crew is its large molecular size, which doesn’t allow it to penetrate the outermost skin layer, making it work gentler. What’s more, lactic acid acts as a humectant, so it draws moisture into the skin and helps consolidate the protective barrier by increasing levels of ceramides, collagen, and elastin.[1]

Lactic acid serum benefits

There’s no denying lactic acid has myriad benefits for your skin. Generally, lactic acid serums offer mild exfoliation and stimulate cell renewal, which is why they’re used to improve texture, minimize fine lines and wrinkles, fade hyperpigmentation, and keep skin plump and radiant. 

Are lactic acid serums safe?

Overall, lactic acid serums are suitable for all skin types and are considered safe when applied in the right concentration. According to the Cosmetic Ingredient Review (CIR) Expert Panel, lactic acid is safe in OTCs when used at a concentration of a maximum of 10%.[2]

Because it’s gentle and hydrating, lactic acid is beginner-friendly and easily tolerable.[3] But like any other AHA, lactic acid can still cause irritation, rash, and itchiness, so you should start low and slow to help your skin build tolerance, especially if it’s easily reactive.

How to use lactic acid serums?

Above everything, you should always perform a test patch on a small area of the skin before applying the product to the face. To be on the risk-free side, start using your lactic acid serum once every two or three days and observe how your skin reacts. If you notice your skin is not drying or irritating, go for daily use. Preferably, you can use an occlusive moisturizer to seal the moisture pulled by lactic acid into your skin.

Usually, AHAs, including lactic acid, increase skin sensitivity to the sun, so it’s better if you apply them in your nighttime routine and always wear sunscreen during the day.

SkinCeuticals C+AHA Exfoliating Treatment

Combining 15% pure vitamin C with 10% AHAs, this serum fights wrinkles, uneven tone, and anything in between. Vitamin C increases the defense against sun damage, preventing photoaging and further skin discoloration, and helps induce collagen production. In the meantime, glycolic and lactic acids exfoliate, speed up cell turnover, and boost collagen for evener, and plumper skin. Bonus points for the lightweight texture that never leaves the skin sticky.

The high-concentrated acids cocktail tackles everything from wrinkles, dark spots, and sun damage to breakouts and excess sebum. Additionally, the formula includes skin replenishers, such as peptides and ceramides, to offset possible dryness or overall discomfort.

Dermalogica Biolumin-C Serum

Loaded with lactic acid and two sources of vitamin C, Dermalogica Biolumin-C Serum works like a charm at fighting dullness, uneven tone and texture, fine lines, and loss of elasticity. A bit of an overachiever, this serum packs a bunch of peptides to encourage collagen production and hyaluronic acid to increase hydration and plump fine lines and wrinkles. Although the serum addresses all skin types, some people with easily reactive complexions claimed the serum was too harsh for them.

Even better, unlike most serums, this one has a creamy texture that relieves skin instantly, as it feels intensely moisturizing and rich.

There are also two humectants (actives that attract moisture into the skin), sodium hyaluronate and glycerin, that help keep the complexion hydrated, plump, and supple. Bonus points because the formula lacks alcohol, oil, and fragrance. This is a leave-on serum and should be used in your PM routine.
