Serum with thousands of five-star ratings ‘takes years off face’

Beauty shoppers are raving about a lightweight serum that has built a loyal following on the Trinny London website. With thousands of five-star reviews, many users are praising how it helps skin look more refreshed over time.

Now, the Peptide+ HA Serum Plump Up is up for grabs for £72 for the full-sized 30ml bottle on the Trinny London website. Rather than relying on fragrance or heavy textures, the serum is said to be designed to work quietly in the background, supporting the skin with proven activities that target fine lines and the loss of bounce. 

It is suitable for both morning and evening use and fits easily into existing skincare routines. The serum was created to visibly firm, hydrate and support skin structure, using a blend of peptides and hydrating ingredients that work together to improve elasticity.

One of its key ingredients is hexapeptide-9, which is said to help strengthen the skin by encouraging collagen production, making fine lines appear smoother and skin feel more resilient. Oligopeptide-1 also plays a role in supporting collagen and elastin, the site says, helping skin maintain a firmer, more lifted appearance over time.

A high-tech four peptide complex adds further support by helping to improve elasticity and firmness. Peptides act as messengers within the skin, signalling it to produce more of the proteins responsible for structure and bounce. 

Alongside this, hyaluronic acid delivers deep hydration by drawing moisture into the skin, helping to plump and visibly smooth fine lines, while natural betaine supports long-lasting moisture retention. The formula has a lightweight gel serum texture that absorbs easily without feeling sticky or heavy, making it suitable for layering under moisturiser, SPF or even mixed with foundation for an added hydration boost. 

It is fragrance-free, making it a good option for those who prefer minimal formulations. To use, shoppers should apply one pump to the face and a second pump to the neck and décolleté, morning and evening, after cleansing and before moisturising. 

Used consistently, the serum is designed to help skin look firmer, smoother and more hydrated, supporting a healthier-looking complexion over time. Another option, however, is the Multi-Active Glow Serum for £60 from Clarins. 

This is said to be a bi-phase serum that ‘boosts radiance, smoothes the skin and evens out the complexion’, and when using it, it can be applied to a clean face every day, morning and/or night. A second is the Liz Earle Superskin Advanced Firming Serum in Moisturiser 50ml for £36, down from £45, on LookFantastic. 

This is an ultra-hydrating serum moisturiser which is infused with rosehip oil and acacia tree extract. The Peptide+ HA Serum Plump Up is, however, rated highly online.

One person hailed it as a ‘miracle’, adding: “I absolutely love this product! Used alone or under a moisturiser it feels amazing. Literally takes years off your face!”

Another said: “Very very nice product, skin looks plump, glowing, and bouncy, I love it. Thank you.” A third person commented: “For plump and radiant skin! On my second refill now.”

A handful of others disagreed slightly, saying: “Too early to tell yet.” Another commented: “I have been using the product – Plump Up for about two weeks. I think it is too soon to tell if it works.”
