Not sure whether lactic acid is the right acid for you? Our lactic acid glossary entry sets out how its larger molecule size makes it milder than glycolic and why it doubles as a humectant, and our guide to AHAs and BHAs compares the two acid families so you can match the exfoliant to your skin type before you buy.


Frequently asked questions

Which lactic acid product should I start with?

Start with AlumierMD Bright & Clear Solution as a daily lactic-acid toning step, then add AlumierMD AHA Renewal Serum two to three evenings a week. Bright & Clear refines the look of tone and texture without the sting of stronger acids. AHA Renewal deepens the resurfacing once your skin is comfortable.

How do I fit the Enzymatic Peel and Refining Clay Mask into my week?

Use AlumierMD Enzymatic Peel once or twice weekly on cleansed skin, leaving it on for the time stated on the label before rinsing. Alternate with the AlumierMD Refining Clay Mask on a separate evening to draw out congestion. Keep daily acids and weekly masks on different nights so skin never feels overworked.

Why choose lactic acid over glycolic?

Lactic acid is a larger AHA molecule than glycolic, so it resurfaces more gently while also drawing water into the skin for a hydrated, smoother finish. That dual action makes Bright & Clear Solution and AHA Renewal Serum suited to drier and more reactive skin. You get brighter-looking tone without the tightness stronger acids leave behind.

Is lactic acid gentle enough for sensitive skin?

Yes — lactic acid is one of the mildest AHAs, which is why Bright & Clear Solution suits sensitive skin and first-time exfoliators. Start two nights a week, buffer with moisturiser, and reach for SkinCeuticals Equalizing Toner to settle pH afterwards. Apply SPF the next day, as exfoliated skin shows sun exposure faster.

Do I still need the Equalizing Toner if I use lactic acid?

SkinCeuticals Equalizing Toner rebalances skin's pH after cleansing and between acid nights, keeping the barrier calm as you exfoliate. Sweep it on with a cotton pad before serums, morning and evening. It makes a noticeable difference to comfort as you build up lactic-acid frequency.
