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 stabilized vitamin C visibly evens skin tone, and starting once a day helps your skin adjust comfortably. Your first full-product order is covered by our 30-day money-back guarantee.

Give it 4 weeks of regular use, morning and night: our clinical testing measured results at 28 days. Results build with continued use, and 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.

Anti-Aging Serum contains no retinoids. Its key ingredients are a stabilized vitamin C, vitamin E and hinokitiol, antioxidants that help skin look smoother and more even. Your doctor or pharmacist can review the full ingredient list if you'd like.

Morning and night, after cleansing and Hydrating Serum if you use it: 1–2 pumps on slightly damp skin, then your moisturizer. Using more won't work better and can cause irritation. The 60 mL bottle lasts about 3 months, the 30 mL about 1.5 months. That's how long it takes to use up, not how long it keeps once opened.

Yes, on the same evening. Apply Anti-Aging Serum first, let it dry completely, then Retinol Treatment. If that combination feels like too much, use the serum in the morning instead.

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.
