No7’s Protect & Perfect line has a loyal following, and it is easy to see why people keep coming back: the serum has one of the nicest textures we have tested at this price. Silky, fast-absorbing, and an excellent base under foundation.
Where it shines
Application is genuinely pleasant. There is no heavy residue and no strong scent, and makeup glides over it. As a daily comfort serum, it earns its place on the shelf.
Where it struggles
The trouble starts when you look for visible change. Among our testers and across long-term user feedback, results split almost evenly: some see a modest smoothing after several weeks, others use the product faithfully and see nothing at all. The tube is also small, so a fair trial ends up costing more than the price tag suggests.
A handful of users also reported puffiness or breakouts in the first days — not the norm, but worth knowing if your skin reacts easily.
Our verdict: Good — 3.9/5
A lovely everyday serum with real cosmetic qualities, held back by unpredictable anti-aging performance. Worth a try if texture is your priority; less so if you want dependable visible results.
