‘Great for dark spots!’ fans rave about vitamin C mask that makes an ‘immediate difference’ – and Amazon has a coupon

A BEAUTY product is quickly becoming a staple for those looking for a flawless complexion.

The skincare product is anti-aging and is currently discounted 10% off with a coupon from the website.

The product is formulated with vitamin C as well as retinol to even out the skin tone.

Saturday Skin is also inspired by Korean skincare, making it a classic choice for beauty fans.

The formula is also "boosted" with niacinamide and glycolic acid for added smoothness.

It is also fortified with yuzu — a citrus fruit known for it's high vitamin C content according to The Cleveland Clinic.

PROOF IS IN THE PUDDING

The ingredients in the Saturday Skin Yuzu Vitamin C Sleep Overnight Face Mask are known to be beneficial for the complexion.

The Cleveland Clinic said that niacinamide increases keratin in the skin as well as making it "stronger."

According to a study on vitamin C, it can help with anti-aging efforts.

Yet another study showed that due to alpha-hydroxy acids (AHAs) in glycolic acid, it may help with smoothing skin.

Retinol has also been shown to slow down the aging process in another medical journal.

Several satisfied customers chimed in to praise the science-backed skincare product.

"With regular use this product has actually reduced and faded them much to my surprise.
