WHO IS SHANI DARDEN

Considered the secret behind Hollywood’s most flawless faces, expert esthetician Shani Darden sets herself apart with her results-oriented approach to skin care.

9% Lactic Acid (AHA) polishes away dead skin cells to reveal smoother, brighter, more glowing skin.
Gluconolactone (PHA) exfoliates, evens tone, improves clarity and hydrates.
Exclusive Soothing Complex contains four molecular weights of Hyaluronic Acid plus Aloe Vera and Green & White Tea Extract to soothe skin and minimize irritation.

What it is

A powerful-yet gentle 9% Lactic Acid Serum that brightens and refines dull and congested skin so you can wake up to an instant glow. Dual exfoliating acids—including Shani's go-to Lactic Acid & Gluconolactone (PHA)—smooth, refine and re-texturize while an exclusive Soothing Complex calms the skin & minimizes irritation.

How to use

Your Glowing Skin Serum

In PM routine (Retinol Reform rest nights), apply Lactic Acid Serum after cleanser and toner, apply 1-2 pumps all over face and neck and smooth into skin, avoiding the eye area. Wait 5 minutes for product to absorb and follow with moisturizer. Be sure to apply SPF in the AM, as freshly exfoliated skin is more susceptible to sun.

Not using retinol in your routine? Lactic Acid Serum can provide similar smoothing, brightening benefits. Incorporate it gradually into your routine, 1-2 times per week to start and use as often as your skin can tolerate.

Glowing Skin.
This product is perfect if you cannot tolerate a retinol . But pared with Retinol Reform it is powerful in creating smooth, refined skin and pores. It’s gentle enough, for me, to put around my eyes. It also gives an instant glow and brightening effect, making me look well - rested. Very good product that I’ve been using for four years.

I should have taken before and after photos, but I failed. The lactic acid did smooth my skin and i noticed that there was some brighter color to my skin.
