What it is: A self-tanning booster for your face designed to be mixed drop by drop into your body lotion for a buildable, even golden glow.

Who it's for: All skin types.

What it does: Formulated with Clarins' skin care and phyto-expertise, this plant-based formula is enriched with a Self Tan Complex of DHA and erythrulose, two 100% naturally sourced plant sugars, along with hydrating glycerin for effortless application and natural-looking, streak-free results.

Research results:

In a consumer test on 61 women after 10 days of use:

- 100% said it delivered uniform color

- 91% said it tailored to their skin tone

- 81% said it delivered a long-lasting tan

How to use: It must be mixed with your day or night face moisturizer. Never use this formula alone. For best results, apply to clean, dry skin that has been exfoliated. Hold the bottle upside down, squeeze the bottom and mix 2–3 tanning drops with your face moisturizer in the palm of your hand. Apply evenly in circular motions, gently sweeping from the center of your face outward toward your ears and down over your neck and décolletage. Avoid your eyebrows and hairline. Wash your hands with soap and water immediately after use then wait a few minutes before getting dressed. Apply 3–4 times a week to create and maintain a sun-kissed natural glow, or use it to enhance or even out an existing tan.
