1A Retinal + Peptides Overnight Mask
The 1A Overnight Mask is what happens when a brand refuses to let any single ingredient carry the entire formulation. Retinaldehyde, a 13.5% peptide complex, niacinamide, glutathione, ergothioneine, pterostilbene, and a half-dozen other actives share the work, and the result is one of the most thoughtful retinoid formulations on the market — assuming you can stomach the price.
