Gently powerful 10% vegan lactic acid serum boosts skin cell turnover, which slows down (a lot!) as we age. Our lactic acid serum is an alpha hydroxy acid (AHA) that effectively exfoliates skin. We’ve completely reimagined ours. It’s vegan—made from sustainably sourced sugar. And we chose 10%, the amount proven to give powerful resurfacing results while still gentle enough to use nightly. This clean dream team’s addition of balancing clover and hydrating squalane will take your skin from dull to luminous in a single night. Get ready to wake up to wow with Biossance's vegan lactic acid serum.

For external use only. Use only as directed. Avoid eye area. We recommend a patch test prior to use if you are particularly sensitive. If irritation occurs, consult a dermatologist.

Smoother, softer skin!

This Squalane %2B Lactic Acid Resurfacing Night Serum was gifted by Biossance to me for the purpose of my honest review, but all opinions are my own. I've been using this Squalane + Lactic Acid Resurfacing Night Serum nightly as part of my skincare routine for a little while now and I really enjoy this product. The product is a lighter cream that absorbs quickly and isn't greasy or sticky feeling. It has a slightly sweet scent that disappears after a short time. I love this product because I really notice a difference in the appearance of my skin's texture after using. It makes my skin look and feel smoother and softer. I also like that this product is a clean beauty product and made from plant derived squalane.

i really like this so far!

I was gifted by Biossance this Squalane %2B 10% Lactic Acid Resurfacing Night Serum in exchange for my honest opinion. I have been using this serum for the past 4 nights after washing my face, and so far I really like it!! The fragrance of this serum was a bit strong at first, but you get used to it quickly. This serum is very gentle on the skin, and my face does look brighter after using this serum. I haven't noticed too much difference in my pores yet, but a few pimples I had went away within a few days of using this serum! I also like that this serum is not sticky like a lot of other serums are, and that I don't even need to use moisturizer after using this serum because it doesn't dry my skin out at all. I also like that this product is vegan and uses clean ingredients! It's also gluten-free and cruelty-free! I'm very excited to see how my skin will look once I've used this for longer! I think I would definitely purchase this serum in the future, and I know I definitely am interested in checking out other products from Biossance now that I have discovered this brand!!

Minimizes pores and helps with texture

I have tried so many serums and this one really helps with my texture and smooths out my skin overnight. I use this after a cleansed and toned face before my moisturizer and face oil. I’m currently on my 2nd bottle. Really satisfied with my purchase.

El producto es excelente, tiene una textura de crema ligera pero hidratante toda la noche mi cara está suave, no tiene casi olor. Cuando se me acabe este producto seguro lo compraré súper recomendado. Mi piel es mixta deshidratada. Gifted by Biossance.
