  • 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.

Diminishes dark spot

I’ve been using this serum for over a month now and I’ve noticed my dark spots have been diminished greatly by using it nightly. I wake up with clear and bright skin in the morning. What’s not to love!

Surprisingly amazed

I’m not one for a skin care routine but a friend bought me the travel sized of this first and i found that it made my face really smooth, soft, and hydrated. So I went ahead and splurged on this product. So far i really like it.

My Skin is so soft - OVERNIGHT

Starting off by starting this is the first time I try Biossance. I was using a product from Monat that i was gifted and loved, but didn't love the price. So price and ingredients play a huge factor in selecting a new product line. Im pregnant and have super sensitive skin, while also wanted to ensure that anything I use was safe for me a baby. I had these little bumped on my forehead that you couldn't see looking at me straight on but I could see them in the right light and feel them. The texture of my skin was a little rough, maybe due to the change of hormones. I used this serum once and the next day the bumps were gone. Yeah, it's that good. I will definitely be purchasing more of the line, and for sure refill on this item when it's time. Seriously, don't skip on this one. When it comes to skin care and make up, less is more for me, and quality over quantity. This checks all the boxes.

Amazing product

First got to know this product through a sample I received from Sephora and i immediately fell in love , had this on my wishlist forever Bc of the price but finally gave in and bought the full size and honestly the quality is amazing.it’s worth the price. It prevents break outs , clears black heads . I use it 3 to 4 times a week at night and wake up with glowing clear skin every time normally I don’t like scents in my skincare but this one smells so good I couldn’t resist

Purging

I used this one time and had triple the amount of breakouts on my chin then normal. I had no other issues (ie. redness, burning) on my face after the first use. I’m not sure if this is purging and when/if I should use it again??
