Yes. Developed by Dr. Rivers for sensitive skin, it's formulated without parabens and without added fragrance, including masking scents. Fragrance is one of the most common causes of skin irritation. Its 4% glycolic acid reveals smoother, brighter-looking skin, and starting once a week helps your skin adjust comfortably. Your first full-product order is covered by our 30-day money-back guarantee.

No, not usually, and it doesn't need to: it's a chemical exfoliant, not a peel-off mask. Its 4% glycolic acid loosens dead surface cells so they rinse away, leaving skin looking smoother and brighter. A mild tingle during the 20 minutes is common, and you don't need to feel it for the peel to work.

Exfoliating Glycolic Peel contains no retinoids. Its key ingredients are 4% glycolic acid, an alpha hydroxy acid that exfoliates to leave skin looking smoother and brighter, and hinokitiol, an antioxidant. Your doctor or pharmacist can review the full ingredient list if you'd like.

Up to twice a week, in the evening. New to acids? Start once a week for the first 2 weeks. At that rate, the 60 mL bottle lasts about 5 months, and the 30 mL about 2.5 months. That's how long it takes to use up, not how long it keeps once opened.

Apply 4–5 pumps to clean skin in the evening, leave it on for 20 minutes, then rinse with warm water. Using more won't work better and can cause irritation. Glycolic acid can make skin more sensitive to the sun, so wear a broad-spectrum sunscreen of SPF 30 or higher every morning while you're using it, and for a week after you stop.

Your usual Riversol serum and moisturizer, as the directions say. Pat your skin dry after rinsing, then apply them as normal; the peel leaves skin feeling softer straight away. Keep retinol for the next evening, so you get the benefits of both without doubling up.

No. Use the Glycolic Peel on a non-retinol evening, up to twice a week, and go back to Retinol Treatment or the Neck Cream the next evening. Alternating this way lets you have both: the peel's exfoliation and retinol's smoothing, without asking too much of your skin in one night.

Hinokitiol is our signature antioxidant, found naturally in the Pacific Red Cedar and studied for decades. It's a natural antibiotic, anti-inflammatory and antioxidant with other skin-revitalizing properties, and in our formulas it helps to even skin tone, reduce the look of sun damage and correct dark spots.

Our skincare products are produced and tested to the highest standards of tolerance on sensitive skin. They are hypoallergenic, fragrance-free, colorant-free and cruelty free.
