Squalane + Lactic Acid Resurfacing Night Serum
Biossance’s Squalane + Lactic Acid Resurfacing Night Serum has potential for being a good AHA exfoliant for all skin types – except for a couple of ingredients that do more harm than good.
Packaged in an opaque tube with a pump dispenser that protects its ingredients from light and air exposure, this treatment has a lightweight lotion texture. Upon application, it absorbs quickly without stickiness or greasiness, making skin look instantly refreshed and plumped.
The star ingredient here is 10% lactic acid, an alpha hydroxy acid (AHA) that research shows improves the look of fine lines and wrinkles, as well as sun damage and dehydration. It’s formulated here at a pH of 3.8 (within the optimal range of between 3-4), meaning it will successfully exfoliate skin for visible results.
Backing this up is squalane, an ingredient Biossance includes in all its skin care products. Squalane is a rich source of fatty acids and antioxidants, and is emollient without feeling heavy or occlusive.
The formula also includes Lespedeza capitata extract, a type of clover that Biossance claims can help balance skin. While there’s no specific evidence that’s the case, it does have antioxidant properties, as most plant extracts do. Besides, balancing skin is never about just one ingredient, it’s about a complete routine that works for your skin type and concerns.
Unfortunately, this also contains lavender oil and the fragrance ingredient linalool, both of which put skin at risk for irritation. They’re not in the highest amount here, but the lavender smell is apparent as soon as you pump out this treatment, and it lingers for some time after application.
It’s a shame, because otherwise this would have been a good option for gentle exfoliation. As it stands, you’re better off with one of the alternatives you’ll find on our list of best AHA exfoliants.

Gently powerful 10% vegan lactic acid serum boosts skin cell turnover, which slows down (a lot!) as we age. Lactic acid is an alpha hydroxy acid (AHA) that effectively exfoliates skin.

Get ready to wake up to wow with Biossance's vegan lactic acid serum.
Biossance is the commercial beauty arm of biotechnology brand Amyris. Amyris manufactures plant sugars (like that from sugar cane) into specialty ingredients for use by other companies, but chose to center Biossance around one ingredient in particular: plant-based squalane.
Each Biossance product prominently features squalane; so much that it’s in the name of every offering. Squalane has its merits—it’s an excellent skin-conditioning ingredient and has antioxidant properties—but skin needs much more than one focused ingredient to feel, look, and perform its best.
Thankfully, Biossance includes other ingredients in many of its squalane-centric products and these are also impressive, particularly bakuchiol (which has many retinol-like properties), antioxidants, and peptides. Unfortunately, the brand also uses a number of fragrance ingredients in many of its products, and whether naturally-derived or not, fragrance is known to irritate skin—even if you don’t see or feel the damage taking place. For this reason, most of the brand’s offerings wind up being middle-of-the-road, though there are a couple of standouts.
