No7 calls this a line-correcting booster, and the target is the part that matters: laugh lines and deep wrinkles rather than a vague all-over anti-aging pitch. We dabbed it along the smile lines above the mouth and found the texture light enough to disappear under sunscreen or makeup. It went on without a heavy perfume note, which we appreciated in an area that can be easy to irritate.
The formula leans on collagen peptides rather than retinol, so it is a gentler entry point if your skin reacts to retinol. In our testing, it layered without pilling and didn't leave the tight film some line fillers do. The 15 ml bottle is small but typical for a targeted serum; a little goes a long way.
The packaging is the annoyance: the bottle can be fiddly to dispense, especially when you want a small amount exactly on the line. We also found the finish easy to live with, which matters more than a dramatic instant tighten. For a targeted product, that combination is hard to beat in this group.
Bottom line: We recommend No7 for the lines just above the lip because it is targeted, lightweight, and fragrance-free, with a texture that layers cleanly under makeup.
