Sunday Riley wants you to benefit from better-looking skin this Amazon Prime Day by offering its award-winning Good Genes Lactic Acid Treatment for 20 percent off. The holy grail exfoliating treatment boasts four skin benefits in just one serum to remove dead skin cells, improve the appearance of texture, fine lines and discoloration, and unearth radiance.
Unlike most skincare lures, Good Genes is one worth the hype. Its miracle formula is designed to work quickly: Buyers notice minor skin improvements (we’re talking visibly reduced dark spots, fine lines and wrinkles) in just three minutes, according to an independent study conducted by the brand. All of this is thanks to several star ingredients, including lactic acid (a chemical exfoliator that revitalizes and plumps fine lines), licorice root (a skin brightener), and a combination of soothing agents, featuring blue agave and prickly pear.
As if that doesn’t already simplify your skincare regimen, Good Genes can be applied after cleansing in the morning or evening, and only requires the use of an SPF alongside it to reduce the chance of skin irritation. (Lactic acid is an alpha hydroxy acid that can cause skin sensitivity to sunlight.)
Shoppers seem to agree that the formula delivers noticeable results. Customers describe skin that looks luminous, supple, and glowing, with one reviewer comparing the results to “medical-grade” treatments sans needles. “Like time travel in a bottle,” says user Sara A. Garcia.
The serum also receives positive feedback for its smooth texture and pleasant fragrance. “Super effective yet gentle, very moisturizing, and smells ah-mazing,” adds user B. Beauvais, who shares that she once thought the product was too expensive until she tried it herself.
The 1-ounce treatment is usually listed at $85, but with Prime Day’s 20 percent off discount (using Skincare Essentials code “LOVE20” at checkout), the price drops to a whopping $68 before tax and shipping. Sunday Riley lovers can save an additional 10 percent (aka $8.50) when signing up for “Auto-Replenish & Save,” a renewal subscription that provides a special discount for brand loyalty shoppers.
Good Genes is one of several targeted treatments from Sunday Riley. The brand’s genius lineup includes the C.E.O. Collection (tackles discoloration using potent vitamin C) as well as its A+ High-Dose Retinoid Serum (supports anti-aging and a smoother appearance). But what might be most notable about the brand is its ability to support skin concerns surrounding hydration, acne, and congested skin using clean and sustainable formulas without compromising quality or integrity.
For anyone looking to streamline their skincare routine, the Good Genes four-in-one treatment is the best way forward. With shoppers praising its glow-boosting results, Amazon’s Prime Day discount offers an opportunity to reap this all-star’s benefits for less.
