| Verdict | Bioderma's hero hydration serum, anchored on the brand's Aquagenium complex — a proprietary aquaporin-activating blend that targets the cellular water-channel proteins responsible for skin's hydration capacity. More biotechnology marketing than other Bioderma SKUs, but the underlying HA + glycerin + niacinamide trio delivers measurable plumping. | The OG retinol serum — RoC has been stabilizing retinol since the 1960s and this formula shows six decades of expertise. |
