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 humectants hydrate dry skin, and its oil-free formula suits oily skin too. Your first full-product order is covered by our 30-day money-back guarantee.

Give it 8 weeks of morning and night use: our trial followed people for 8 weeks. Skin feels hydrated from the first use, and the smoother look of fine dehydration lines builds over that time. Daily sunscreen protects the progress you make.

Choose by your main concern. Anti-Aging Serum has 10 times the stabilized vitamin C (aminopropyl ascorbyl phosphate) of our Anti-Redness Serum, for fine lines and uneven tone. Anti-Redness Serum has a lower level of vitamin C, formulated for visible redness. Corrector V2 helps fade the look of dark spots, and Hydrating Serum adds hydration and layers with all three.

Hydrating Serum contains no retinoids. Its key ingredients are hyaluronic acid, polyglutamic acid, beta-glucan and glycerin, which hydrate the skin. Your doctor or pharmacist can review the full ingredient list if you'd like.

Right after cleansing, or after Corrector V2 if you use it. Apply a dime-sized amount to slightly damp skin, before your other serums and moisturizer, which seals in the water it draws in. A little goes a long way. Using more than the recommended amount won't give you better results, and too much product is a common cause of irritation.

No. It's lightweight and silicone-free, and it absorbs quickly with no residue. Let it sink in for a minute before sunscreen or makeup, and use a dime-sized amount, not more.

About 2 months, used morning and night. The 30 mL bottle holds enough for a dime-sized amount each time. That's how long it takes to use up, not how long it keeps once opened.

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.
