If dewy radiance is what you’re after – and who isn’t? – then this refillable serum from fashion guru Trinny Woodall is worth a splurge. It champions faster-acting retinal in a bid to help mature skin look plumper and feel silkier more quickly.

Our lab test found it minimised fine lines and wrinkles, with testers finding it easy to dispense and saying they received compliments from friends. Just note that first-time users may prefer to go for a retinol option.

Neutrogena is a brand known for its affordable, effective and super accessible formulations. In recent years, it has also developed some really clever tech that you may not expect from the price point. In this serum, myrtus plant extract has been mixed with retinol, something the brand claims improves efficiency of delivery by 83%. Plus, the extract also lends the product with a wonderful woody fragrance.

Everyone agreed that it was easy to use, with one tester saying it made the age spots on their face vanish. Panellists also all agreed that their skin felt smoother, looked brighter and felt far more hydrated (hello, hyaluronic acid) after use. Not bad for less than £30 (and even better if you can get it on sale!)

Skincare guru Caroline Hirons has a lot of beauty strings to her bow, and this best-selling targeted retinol from her brand, Skin Rocks, is another insider favourite. We received lots of love for the pump applicator packaging, which all our testers found super easy to use and less wasteful.

In the lab, we looked for any improvement in fines lines and wrinkles, texture and pores over an eight-week period, using a VISIA face analysis machine. The results showed that this was the most effective of all formulations tested at improving the appearance of fine lines and wrinkles, texture and pores, although the tester feedback was slightly more mixed.

Everyone agreed skin felt firmer and their complexions looked improved after use. It also layers well with other products. It’s designed to be suitable for sensitive skin, but a couple of testers who were unused to using retinol had slight irritation with this one, so make sure you take things slowly.

Score: 79/100

Formulated with bakuchiol – nature’s answer to retinol – this one really was hard-working when it came to brightening skin and smoothing out texture. Everyone agreed their face looked brighter and more even in tone after using this for the trial period.

They told us it felt lovely and lightweight on skin, working to reduce many of their dark spots, and although some noticed an initial tingle, it didn’t last too long.

With ingredients such as olive squalane and organic aloe vera juice, plus plant-derived humectants, this fresh formulation is made for hydrating skin and locking in moisture.

This serum’s grown-up glass packaging will look smart by the side of your sink, plus it packs a real punch when it comes to achieving that illusive ‘I-woke-up-like-this' glow. One tester told us: “This is the best retinol product I’ve ever used – within about two weeks, my skin started looking more even toned, plumped and glowing.” Get that for a rave review.

The oil-serum formulation sank into skin easily and everyone agreed it had a pleasant texture, with one person noting the “nice, clean scent”.

One panellist said they didn’t experience the same sensitivity and redness they often get with other retinol serums, and another added that they found it very hydrating, so much so that they didn’t feel the need to follow up with a moisturiser at night.

Score: 77/100

An instant spa-style glow is what our lucky testers enjoyed after sweeping this fast-absorbing serum over their skin. Beginner-friendly with its minimal 0.15% retinal content, many said their complexion looked brighter and smoother four weeks in, with more firmness and fewer fine lines reported after eight. “My skin has genuinely never looked better,” declared one panellist.

It also impressed our lab team on the slow-ageing front, albeit not quite as much as our top two.

Score: 76/100

Here’s another good value retinol formula that earned a big tick in the Good Housekeeping Institute lab for improving skin texture and making pores and wrinkles look less noticeable. Our testers reported similar success, especially in terms of smoothing, and liked how lightweight it felt to apply.

Over half found it “deceptively strong” though and said they struggled with some initial tingling and flakiness, but one panellist said she liked the “sloughing off” effect and was left with a clearer complexion by the end of the trial. Our advice? Use it sparingly at first and see how your skin reacts.

Score: 75/100

This lightweight, creamy serum was a big hit with our testing panel, who rated its texture – one person told us it “melted into skin seamlessly” while another said it was “silky” without being sticky or leaving any tacky residue. It earned further praise for its subtle, fresh scent, and many were impressed with the mess-free pump applicator compared to their typical pipette.

But did it actually do much besides feeling nice on skin? Well, it scored 3/5 in the lab for softening fine lines and adding glow, and many reported a smoother skin texture.

In terms of dark spots or forehead lines, however, effects were more modest than some of our testers had hoped. It’s a pleasant formula and easy-to-use serum that’s perhaps best reserved for beginners, or those looking for something light and gentle.

Many of us probably remember the Avon catalogue dropping on the door mat and coveting all the latest lipstick shades. And the brand is still going strong, creating affordable and accessible beauty products on an international scale.

This serum had a spreadable consistency and absorbed quickly into skin, with an inoffensive, pleasant smell and a non-tacky residue. Someone told us their skin felt great immediately afterwards and was “neither too oily nor too dry.”

Everyone agreed it was lightweight and liked the fact the bottle was transparent, so they could see when they needed to replace it. “My skin felt moisturised, and I got lots of comments saying I looked like I had a glow after just one week of use,” said one happy tester. High praise, indeed.

Score: 74/100

Testers loved the lightweight, silky feel, with one saying it “melted into skin”, absorbed quickly and left no greasy residue. The pump made it easy to control the amount dispensed, and after a couple of weeks many noticed their skin looking radiant and fresh, feeling plumper, with wrinkles appearing smoother. Makeup also layered well without slipping, according to our panel.

Some people experienced initial redness or dryness – particularly around the nose – when first introducing it to their routine, though this typically settled. A few mentioned formula separation in the tube and wished the retinal strength were stronger, but overall, it’s a great value, fast-absorbing formulation for those who don’t like heavy creams.

Score: 74/100

If your skin is lacking lustre, let there be light with this brightening serum. It’s made with encapsulated retinol, which helps the active ingredients penetrate more deeply.

It’s a luxe-looking product with a price tag to match, but our testers loved how much radiance it gave their tired complexions. They found it lightweight in texture and quick to absorb. Nearly everybody agreed that it shrunk large pores, with our lab team finding it decent at banishing wrinkles.

Score: 74/100

For skin as velvety as a baby’s, this retinol serum is the way to go. Our testers found it luxuriously silky to apply and said it glided on, making for a pampering nightly ritual.

It softened, smoothed and brightened brilliantly, giving almost all our panel that post-holiday glow (without the air miles) after a month. It also helped even out skin tone and made deep wrinkles less obvious. Yes, it’s expensive, but it’s cheaper than a flight to the Caribbean…

Score: 74/100

Though relatively slow to get going, with just over half of our panel finding their fine lines and wrinkles improved after a month, this retinol serum got the anti-ageing thumbs up from our lab team after eight weeks.

It excelled in the texture stakes, helping dry complexions look clearer and leaving them feeling smoother, while most testers said their skin felt more hydrated by the end of the trial. Better still, a small drop spread all over the face, making it excellent value for money.

Score: 71/100

We told you Medik8 knows what it’s doing where retinol’s concerned – this is the brand’s second appearance on our skin-firming hotlist. “The pump action worked well because it could be stored upside down so the product drained into it,” said one tester, while another added: “It felt light and comfortable going onto my skin and was easy to spread.”

Some didn’t love the yellow hue, and one noticed it transferred onto their pillow. Another mentioned that it didn’t do much to dark spots, but everyone said it improved the appearance of fine lines, wrinkles and pores, agreeing that their skin felt firmer and softer after the trial.

Score: 70/100

Known for its ingredient-led, scientific approach, we had high hopes for this classic serum from The Ordinary. One tester told us: “A couple of people commented that my skin looked brighter and asked what I was doing differently”.

Almost everyone agreed that their skin felt more hydrated after use, too. It made a great first impression because of how speedily it absorbed into skin and won praise for its lightweight texture. “It went on so smoothly without any lingering traces of grease,” said one panellist and many told us it left their skin brighter and firmer come morning.

Some didn’t like having to keep the product in the fridge to keep the formulation stable, with a couple of people saying that while they’d continue to use the existing bottle, they wouldn’t buy it again, purely because of this inconvenience. There were also a few moans about the scent, which many said was “like medicine” – one even noted it was “reminiscent of raw pork.” Niche…
