ABOUT THE LASER SERUM

Inspired by in-clinic laser treatments, the triple acid resurfacing serum is powered by a potent blend of lactic, glycolic, and mandelic acids that gently yet effectively exfoliate and resurface for a brighter, smoother complexion. With different molecular weights, this triple acid complex penetrates multiple layers of the skin to deliver enhanced efficacy and visible results faster.

The formula also includes a blend of extracts (including kakadu plum, licorice root, and rumex occidentalis extracts) that provide antioxidant benefits for visible radiance and help to improve brightness, making it an ideal companion to The Preservationist Vitamin C Serum. To counteract the redness or dryness that are typically triggered by acid serums, the formula leverages biofermentation technology to incorporate natural ingredients (yeast, prickly pear cactus and helischysumflower extracts) that soothe and calm while replenishing and supporting the skin barrier. The result is glowing, glass-like skin that becomes brighter with regular use.

    Exactly what my skin needed

    I’ve been using it now for a week and love how it feels on my skin. Love the way my skin looks in the morning as well after using it before bed

    Astonished.

    I used to be an avid tretinoan/acid user prior to my pregnancy. I’m 41 and have not been able to use anything like retinol, or strong actives on my skin. At one point, my eyes had swollen shut from a “gentle” retinol product. I had resigned myself to the belief I was just going to maintain with gentle actives, and had adopted a complete Augustinus Bader and Auteur skincare routine. Very expensive, and lots of steps. Things were fine enough. I stumbled upon this regimen, and took a chance on the travel sizes. When I used only these and mild cleanser and spf I was stunned! I am 2 weeks out, and my skin looks 10 years younger. The laser serum tingle was non sensitizing, and I’m still baffled by how great my skin looks. No reactions. No eye burning. There’s is something very special here, and I’ve tried MANY products. Hard to put into words, but I’m so thankful for your line. It has simplified my routine, and made the most difference in the smallest amount of time. The travel sizes are perfect to try!

    Excellent light peel!

    This is a great product for sensitive skin, cause it’s not too harsh, a very light peel! But you wake up with a beautiful glow!
