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.

    I will never love another, the way I love this serum

    Honestly THE. BEST. product I’ve introduced into my routine in years. In 12 weeks it: Smoothed out the texture of my skin, lightened my hyperpigmentation from breakouts, reduced ingrowns from tweezing, it even reduced the appearance and feel of the scars I have from a car accident. All while not leaving my already dry skin feeling dry, stripped, or tingly from the acid. I’m absolutely in LOVE. A mild cleanser, this serum, and a moisturizer keeps my daily routine short simple yet extremely effective, which what I require in my skincare routine.

    Goodbye Rosacea

    I’ve struggled with rosacea, enlarged pores, and acne breakouts for years, and I can confidently say this product has been a game-changer! After just three months of consistent use, my rosacea has improved by I would say 90% something I never thought possible. Look at the picture from before I started using the serum, and the one 2 months after. My skin feels smoother, my pores are visibly smaller, and breakouts? Almost nonexistent! Can’t recommend this product enough.

    I am beyond impressed. It’s lightweight, non-irritating, and actually works. If you’ve been searching for a skincare product that delivers real results, this is it! Don’t wait your skin will thank you!

    Absolutely changed my skin!!!

    I've been using the laser serum for 3 months now and I can't express the change in my skin. Having acne prone skin and finding products that actually make a difference has been extremely challenging. I slowly incorporated the Laser Serum into my routine (one night on, one night off), until I finally felt that my skin was ready for everyday use. It only took about a week to see magical results!!! I've received endless compliments on my skin and better yet, have finally been able to walk out without needing make-up. I finally found a product that WORKS! The pics below is only a week apart.

    Triple awesome. ✨

    Amazing stuff. I can feel it working- I use it in my nighttime routine and love it! I’m 40 but feel more confident in my skin than I did when I was 30!
