Quick answer
The best retinol serums state their strength on the label, are backed by real proof, include hydrating and soothing ingredients so you can use them every night, and come with a guarantee. Our top pick is the Dermaworks 2.5% Retinol Night Serum: high-strength retinol, clinically proven to boost collagen by up to 5x, rated 4.6 out of 5 and £14.95.
The best retinol serum is the one that actually delivers everything retinol is famous for: smoother skin, softer-looking fine lines and wrinkles, refined pores and a firmer, fresher, younger-looking complexion. With hundreds of retinol serums on sale in the UK, many of them vague about what's really inside, it pays to know what to look for. Here are the five things that separate a retinol serum that really works from one that doesn't, and why our 2.5% Retinol Night Serum is the one we'd put our name to. Use them to judge any serum, ours included.
5 things to check before you buy a retinol serum
A strength on the label
If a retinol serum doesn't tell you how much retinol it contains, there's usually a reason. "Contains retinol" can mean a tiny amount added for the label. Look for a stated strength. Ours is a high-strength 2.5%, right there in the name.
Proof that it works
Big promises are easy; proof is harder. Our 2.5% Retinol Night Serum is clinically proven to increase collagen production by up to 5x. Collagen is the protein that keeps skin firm, plump and smooth, so this is the result that really counts.
Ingredients that keep your skin comfortable
The biggest reason people give up on retinol is dryness, and you only see results if you keep going. Look for hydrating and soothing ingredients alongside the retinol. Ours includes botanical hyaluronic acid, organic aloe vera, vitamin E and green tea, so it's powerful enough to deliver visible results, yet balanced for night-after-night use.
A lightweight night-time formula
Retinol does its best work while you sleep. A light, fast-absorbing serum sinks into your skin rather than sitting on top, and layers perfectly under hyaluronic acid and moisturiser.
A guarantee
If a brand won't take it back, they're not sure it works either. Every Dermaworks product comes with our 60-day money-back guarantee.

What results to expect, and when
Retinol rewards consistency. Start with 2–3 nights a week, build up to every night, and here's what most people notice:
Weeks 1–2: your skin adjusts
Cell renewal speeds up. A little dryness or flaking is normal and soon settles, especially with hyaluronic acid and moisturiser on top.
Weeks 2–4: smoother, softer skin
Your skin feels smoother to the touch and looks fresher in the morning. For most people, this is the first wow moment.
Weeks 6–8: fine lines start to soften
Fine lines, pores and uneven tone start to look visibly softer, and your skin looks firmer.
Month 3 and beyond: firmer, clearer skin
Firmness and texture keep improving with every night you use it. This is where retinol really earns its place.

Also consider
Is a 2.5% retinol too strong for beginners?
Not when it's made right. Our 2.5% retinol is balanced with hyaluronic acid, aloe vera and vitamin E to keep your skin comfortable, so it suits beginners as well as retinol fans looking for something that really works. The secret is how you start: use it 2–3 nights a week, follow with our Hyaluronic Acid Serum and a moisturiser, and build up to every night as your skin adjusts. Wear SPF every morning, as retinol makes skin more sensitive to the sun.
The bottom line
The best retinol serum gives you a real strength, real proof and a formula you can use every single night. Our 2.5% Retinol Night Serum ticks every box, and it works even harder as part of a routine: pair it with our Hyaluronic Acid Serum at night and our 20% Vitamin C Serum in the morning, or get all three in our 3 Serum Set for £34.95, saving £9.90.
