Take rough, bumpy skin texture and smooth it out in just one week with Lactic Acid Resurfacing Serum. The gentle intensity of this exfoliating AHA delivers a smoother and softer texture, visibly diminished fine lines, and an overall brighter complexion, while the squalane at the heart of the formula soothes and fortifies to make skin stronger and healthier from within. Powerful but non-irritating, the silky serum delivers silky skin—at any age.

  • 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 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.

Overnight results

These pictures are four days apart. In the middle of those four days I stopped using another very pricey “resurfacing” product and switched to Biossance. In essence, this is after using Biossance for two nights. I’m impressed with how quickly I saw a reduction in overall redness and smoother skin. Looking forward to seeing what happens in the coming weeks.

Magic in a pump

This stuff has been a literal game changer for me. My skin could never be smooth enough and harsh abrasive exfoliants always made my skin worse... like sensitive and broken out. Plus my skin never looked clear or uniform enough to go without makeup. This cream has given me my dream, I frequently skip makeup now and can't get over my complexion being so smooth and even toned.

Perfect night treatment

I received a deluxe sample of this from Sephora and have been using it as a night treatment for the past couple of nights. My skin is glowing! The lactic acid clears and gently exfoliates while the squalane keeps me hydrated.
