Mid-Strength Night Serum With Retinol 0.5% in Squalane for Dry Skin

A middle rung for anyone whose skin already handles a starter retinol without complaint. Half a percent of retinol sits in a squalane carrier with no water at all, giving a slippery, cushioning feel that drier complexions tend to appreciate. Sweep a few drops across the face after cleansing at night, seal with a cream, and build frequency slowly rather than going nightly from day one. Kept up, it leaves the surface looking more refined, with softer lines and steadier tone. Daytime sunscreen is essential.
