A new favorite

I was recently introduced to this product during an AOS facial. The Ultra-C Serum has been a perfect addition to my morning routine.

Ultra-C Serum has been a daily part of my skincare for more than two years. It’s my aging skin’s must have vitamins!

I feel like I say this about all of the AOS products...

This serum is incredible! It leaves a really lovely, moisturized but not 'sticky' or 'heavy' feel on my skin. I haven't been using it long enough to notice any significant differences in dark spots/hyperpigmentation stuff, but I love the way my skin looks and feels with it so far!

Amazing product !

I am so glad I got this serum. It feels super light on my skin and I can layer other skin care on top. I also use it as a "spot" treatment after i have gotten hyperpigmentation on my skin from acne or sun exposure. I will defiantly keep this in my arsenal forever.
