Per the instructions, I applied a few pumps onto clean skin in the morning. (You can either apply it to slightly damp skin post-cleanser or after your toner or essence step.) It really melts in the skin, with a refreshing, thirst-quenching feel. I followed it up with my daytime moisturiser and sunscreen and immediately noticed a healthy gleam. (The brand even suggests using a liberal amount as a flash hydrating mask to prep your skin for makeup.) After a few weeks of use, I’m already seeing bouncier, softer skin. I tend to treat my skin with kid gloves (keeping actives to a minimum and not overdoing it with retinol), so my barrier was already in a good place before introducing this serum. However, if you’re looking to get your skin back on track, something like this — or my other go-to barrier serum, The Ordinary’s Soothing & Barrier Support Serum — would be an excellent addition to any routine.
