  • 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.

Best AHA but wish there were size options

Wonderful exfoliator! I use it every other night (mostly because it's pricey for my budget) and I can feel that subtle tinge in my skin that you feel with AHA's and you know it's working! My only complaint is that I wish this came in a larger size.
