Lactic Acid for Skin

Lactic acid, a gentle alpha hydroxy acid (AHA) derived from milk and fruit sugars, works by breaking down bonds between dead skin cells, promoting a smooth and even tone. Ideal for enhancing skin texture and supporting the natural barrier, our lactic acid skincare products help to reveal a fresh, radiant complexion. Incorporate this popular ingredient with our lactic acid cleansers, all formulated to provide gentle yet effective exfoliation.

Frequently Asked Questions

How should lactic acid be used in your skincare routine?

Lactic acid is best applied in the evening after cleansing and before moisturiser. Start by using it a few times per week, gradually increasing frequency as your skin builds tolerance.

Medik8’s Pore Cleanse Gel Intense is a refreshing gel cleanser powered by an AHA/BHA complex, including lactic acid, to visibly smooth skin texture, minimise the look of pores and reduce unwanted oiliness.

Can you use lactic acid and hyaluronic acid together?

Yes, lactic acid and hyaluronic acid make an excellent pairing. While lactic acid exfoliates and encourages cell turnover, hyaluronic acid helps replenish moisture and support the skin barrier. Using them together balances resurfacing with hydration, ensuring smoother, plumper skin with minimal dryness or sensitivity.

Can lactic acid help with acne?

Yes. By exfoliating dead skin cells and helping to unclog pores, lactic acid can reduce the likelihood of breakouts. Its mild resurfacing action also supports more even tone and texture, which can be beneficial for skin recovering from blemishes or congestion.

Which is better: vitamin C or lactic acid?

Vitamin C and lactic acid serve different purposes in a skincare routine, and one isn’t necessarily better than the other. Vitamin C is a potent antioxidant that helps brighten the complexion, supports collagen production, and protects against environmental damage.

Lactic acid, on the other hand, gently exfoliates to smooth skin texture and boost cell renewal. When used together, they can deliver visibly brighter, smoother and more even-toned skin over time.

What should not be mixed with lactic acid?

Lactic acid should be used with care when combining it with other strong actives. Avoid layering it with retinol, vitamin C, or other exfoliating acids like glycolic or salicylic acid in the same routine, as this can increase the risk of irritation. If you’re using more than one active ingredient, as a toner or serum, it’s best to alternate them on different days or apply at different times of day.

Medik8 formulations are designed with ingredient compatibility in mind, helping you build a routine that delivers visible results without compromising skin health. Our cleansers, such as Surface Radiance Cleanse and Pore Cleanse Gel Intense, are rinse-off formulas expertly blended with exfoliating acids, including AHAs and BHAs. These are designed to gently resurface the skin during cleansing without the same risk of irritation as leave-on products.
