Aestura REDERM365 Retinoid Eye Serum

Ingredient analysis and how the ad lines read

Read on 2026-09-21

What is this product?

A retinoid eye serum built around hydroxypinacolone retinoate at a disclosed 50 ppm, supported by niacinamide, adenosine, a vitamin C derivative and three acetyl peptides, with a fragrance-free and essential-oil-free formula. A reasonable pick for an anti-aging eye step, though the low retinoid concentration means expectations should stay modest.

What makes it different?

The formula names its retinoid concentration exactly (50 ppm hydroxypinacolone retinoate), which many brands leave undisclosed. It pairs that retinoid with niacinamide at fifth position, adenosine, 3-O-ethyl ascorbic acid and three acetyl peptides in the later half, plus barrier-related lipids such as cholesterol and hydroxypropyl bispalmitamide MEA. The list is free of added fragrance and essential oils and contains no drying alcohol, which suits a sensitive eye area.
