Best AHA (Alpha Hydroxy Acid) Skincare in Canada
Alpha-hydroxy acids (AHAs) like glycolic and lactic acid exfoliate the skin's surface to reveal brighter, smoother, more even-toned skin. The most effective way to use them is in the evening a few times a week, building tolerance, always paired with daily SPF since AHAs increase sun sensitivity.

The Complete Guide to AHAs (Glycolic Acid/Lactic Acid)
Alpha hydroxy acids (AHAs) are water-soluble exfoliating acids — including glycolic, lactic and mandelic — that dissolve dull, dead surface cells to reveal brighter, smoother, more even skin. Each AHA differs in strength and feel, so there's one for every skin type and goal, from radiance to texture to fine lines. We've curated medical-grade AHA serums, peels and cleansers across multiple trusted brands.
Every product is authentic and shipped from WeDoSkin, a Preferred Authorized Retailer, with fast Canada-wide shipping, free samples, and 5% cashback on every order.

AHAs (Glycolic Acid/Lactic Acid): Frequently Asked Questions
What are AHAs (alpha hydroxy acids)?
AHAs are a family of water-soluble exfoliating acids — most commonly glycolic, lactic and mandelic. They work on the skin's surface to loosen and dissolve dead cells, revealing brighter, smoother skin.
What do AHAs do for skin?
AHAs brighten dull skin, smooth rough texture, even tone, soften fine lines and help fade surface pigmentation by accelerating cell turnover. Over time they also support collagen renewal.
AHA vs BHA — what's the difference?
AHAs are water-soluble and work on the surface for glow, tone and texture, while BHA (salicylic acid) is oil-soluble and works inside pores for oily, acne-prone skin. See our salicylic acid collection.
Which AHA is best — glycolic or lactic?
Glycolic acid is the smallest and most potent, ideal for resilient skin and visible results; lactic acid is gentler and hydrating, better for sensitive or drier skin. See our glycolic acid and lactic acid collections.
How often should I use AHAs?
Start 1–2 times a week and build up as tolerated. Gentle cleansers can be used more often than strong leave-on serums or peels. Increase slowly to avoid irritation.
Can I use AHAs with retinol?
Use them carefully — both renew the skin, so combining them on the same night can irritate. Many people alternate nights or use an AHA cleanser. See our retinol collection.
Do AHAs help with texture and dullness?
Yes — they're among the best ingredients for both, smoothing rough texture and instantly brightening dull skin. See our uneven texture and dull skin collections.
Are AHAs good for sensitive skin?
Gentler AHAs like lactic acid, used at low strengths and low frequency, can suit sensitive skin. Start slowly, patch test, and choose hydrating formulas to minimise irritation.
Do AHAs help with anti-aging?
Yes — by renewing the surface and supporting collagen over time, AHAs soften fine lines and improve overall skin quality, especially alongside retinol, antioxidants and SPF.
Do I need sunscreen with AHAs?
Absolutely — AHAs make skin more sun-sensitive, so daily broad-spectrum SPF is essential to protect your skin and your results. See our sunscreens collection.
