Gave me my confidence back!

For reference I’m 31 with dry, sensitive, eczema prone skin. My face breaks out from the simplest things, whether it’s new foundation, serums, oil, masks, ANYTHING and EVERYTHING! Intense dark acne scars follow along with it. I was recommended this serum as well as the omega repair cream for my dry patches. This brand by far has been the most gentle and effective skin care I’ve ever put on my face. (And I’ve tried a lot of brands! Tatcha, Fresh, Clinique, Youth to the people, and drug store brands... etc) My face instantly glows and after a few weeks, my dark spots that usually take months to disappear, are almost gone!! 100% recommend and will forever be a loyal customer. Thank you Biossance for giving me my confidence back! I barely use foundation these days!

Pleasantly surprised!

I was kinda of anxious how I’d react to this because of having dry/acne prone skin, but this is now going to be a staple in my skincare routine. My skin is glowing and my blemishes have lightened up in just 2 weeks, and I forget to put this on at night sometimes so I’m sure if you did it every night you would get better results! I can’t wait to see a months progress

Perfect Vitimin C for sensitive skin

I have acne prone, sensitive skin. Virtually everything breaks me out with actual acne or tiny red bumps. I've have olive skin and suffer with acne scaring and sun spots and have been looking for a vitamin c serum that doesn't cause irritation. I've been usual for a couple of weeks with absolutely no negative reaction. I'm also using the gel moisturizer and my skin has transformed with a massive reduction in redness and dark spots. I still have some stubborn spots but I'm very happy with the results.
