  • 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 the lactid acid serum 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.

Terrible smell!

I was so excited to try this serum as I love all the other products, and they have made my skin glow! This one however smelled so bad I was gagging. I had to wash my face as I couldn't take the smell. It was horrendous. Like chemical burnt hair smell. I'm very, very disappointed because this is expensive and there is no way that I will ever use it again.

Love it…… but

I love this product, but do NOT get it on your lips!! I woke up to blisters on my lower lip. They are now healing but still looks pretty bad. This product is great for my skin, I have been using once a week for a while, leaves skin soft and smooth. I now know to avoid the lip area.
