- This rapid retexturizing serum with 10% vegan lactic acid dissolves dead surface cells and reveals soft, luminous new skin below.
- Unlike other treatments with long wait times, results are visible quickly—as soon as overnight, or after only 1-2 weeks.
- Lactic acid is a “does-it-all” ingredient that fights uneven texture, minimizes signs of aging, and can be layered with other Biossance treatments to amplify their benefits.

Sunburn alert: ‘Contains Alpha Hydroxy Acids (AHAs) that may increase skin’s sun sensitivity and the chance of sunburn. Use only as directed. Avoid contact with the eyes. If irritation persists discontinue use and consult a physician. It is recommended that prior to exposure to the sun, users cover areas where AHAs have been applied with sunscreen. Contact of the product with the skin must be of limited frequency or duration.’

Leading Ingredients
10% Vegan Lactic Acid: Boosts cell turnover, which slows as we age. Lactic acid is a gently powerful alpha hydroxy acid (AHA) that effectively exfoliates and resurfaces skin.
- SQUALANE: Derived from sugarcane, it mimics body's natural hydrating oils to provide weightless moisture to deliver active ingredients deep into the skin and prevent overdrying.
- Clover: Boosts lactic’s exfoliating benefits by revving up cell turnover. It also helps reset and renew skin after each day’s dose of UV rays, blue light and pollution.
All Ingredients:
Water/Aqua/Eau, Caprylic/Capric Triglyceride, Lactic Acid, Squalane, Glycerin, Sodium Hydroxide, Cetearyl Olivate, Propanediol, Sorbitan Olivate, Cetearyl Alcohol, Lespedeza Capitata Leaf/Stem Extract, Polyacrylate Crosspolymer-6, Acacia Senegal Gum, Sodium Gluconate, Xanthan Gum, Phenoxyethanol, Ethylhexylglycerin, Lavandula Angustifolia (Lavender) Oil, Linalool.

1Is this safe for daily use? If I use this at night, do I need to wash it off in the morning?
Yes, Lactic Acid Resurfacing Night Serum is safe for daily use and does not need to be washed off. However, you can absolutely cleanse your skin during your AM routine if you so desire. -
2Does this contain any ingredients that make skin sensitive to sun exposure?
The AHAs in Lactic Acid Resurfacing Night Serum make your skin more sensitive to the sun, so it is always recommended to wear SPF during the day. -
3How does this product feel when you apply it?
Lactic Acid Resurfacing Night Serum has a creamy texture that penetrates without leaving a sticky after feel. -
4Will this product work on melasma hyperpigmentation?
Lactic Acid Resurfacing Night Serum exfoliates skin, which can help reduce the appearance of discoloration and uneven skin tone. Be sure to wear SPF during the day. -
5 Can this face serum be used with Retinol/Phyto-Retinol?
Lactic Acid Resurfacing Night Serum hasn’t been tested for use with retinol. If you have sensitive skin, it is always a good idea to do a patch test first. If you were to use a conventional retinol with this product a good practice would be to alternate days between this and your retinol product. A great alternative is Phyto-Retinol Serum, which can be used with this and doesn’t have the same photosensitivity as traditional retinol. We suggest Phyto-Retinol Serum in the morning and Lactic Acid Resurfacing Night Serum at night. If you want to use them together, apply Phyto-Retinol Serum first, then layer Lactic Acid Resurfacing Night Serum over.

Game changer product
I absolutely love this serum. My skin is softer and feels more moisturized. It took some getting use to the texture of the product, it can come out runnier sometimes but works great.

Anonymous United StatesFixed The Problem
The skin on my chest had a bad reaction to the one time I tried Tretinoin (retinoid) on it - bumps, redness that wouldn't go away. I used the Squaline & Lactic Acid serum on it and the problem completely cleared up in a couple days!

Brie Y. United StatesI'm a fan!
I've been using this the past 2-3 weeks and found that if I use it once every couple of days it's great. Definitely softening and does not irritate my sensitive skin! I took one star off because the packaging makes it difficult to get the serum once you start running low.
