Retinal B3 Serum

What it is
A skin-renewing serum combining retinaldehyde (a fast-acting form of vitamin A) with niacinamide (vitamin B3) to smooth texture and even tone.

Who it's for
Anyone dealing with fine lines, uneven texture, or breakouts who wants a retinoid that works faster and gentler than standard retinol.

Skin type
Start slow if you're new to retinoids — niacinamide helps soothe as the retinaldehyde works.

How to use
Apply a thin layer to clean, dry skin in the evening, avoiding the eye area. Start with 2–3 nights per week, then increase as tolerated. Always follow with moisturizer, and use SPF during the day.

Why it's in the routine
This is the serum step in our Renewal Routine, alongside Ultra Gentle Cleanser, Moisture Balance Toner, Cran Peptide Cream, and Brilliant Defense SPF 50.
