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.

    Must have

    I mean I don’t know what’s in this, but I trust this completely! Bought this for my mum as she refused to return what’s mine! 🤣

    I can’t wait for my peel pads and I would like to try the entire line! But for now if you’d like to try something from this line laser serum is it
