Shoppers are turning away from high-end serums in favour of a new £27 K-beauty product from COSRX that promises to deliver the coveted 'glass' skin look. The brand, already famous for its viral Snail Mucin Essence, has launched the Blue Peptide Bakuchiol Plump Glow Serum (£27) and the Blue Peptide Bakuchiol Plump Bounce Cream (£28), both available on Amazon.
New COSRX Collection Offers Affordable Anti-Ageing Benefits
The new line combines bakuchiol, a gentler alternative to retinol, with copper peptides. These ingredients work together to improve the appearance of fine lines while supporting skin elasticity. The lightweight Plump Glow Serum is designed to deliver an instant hydration boost, making skin appear smoother, firmer, and more radiant. It can be used in both morning and evening routines.
The Plump Bounce Cream (£28) is a rich moisturiser formulated with ceramides and fatty acids to strengthen the skin barrier and lock in hydration. It leaves skin feeling bouncier, smoother, and more resilient. COSRX advises against using these products alongside vitamin C, as it can destabilise peptides and reduce effectiveness. For those who use vitamin C, the brand recommends applying it in the morning and reserving the Blue Peptide range for evening.
Early Reviews Praise Hydration and 'Glass Skin' Glow
Early reviews for both products have been positive. One shopper said of the serum: 'It glides smoothly onto the skin and absorbs quickly without leaving any sticky or heavy residue behind. My skin feels instantly bouncy and deeply hydrated right after application. After using it consistently, I have noticed a visible improvement in my skin's overall plumpness and a subtle, healthy glass skin glow.'
Another added: 'After use and the rest of my routine, my skin feels hydrated and bouncy, and all around more comfortable. I am really enjoying using this so far, and think long term it would probably help with hydration of skin.'
Some Sensitive Skin Users Warn of Alcohol Content
However, not all feedback is glowing. One user cautioned: 'If you have sensitive skin, beware that this formula contains alcohol. My sensitive skin couldn't handle it, but it's a good formula regardless; I wish it were alcohol-free.' On a brighter note, a Bounce Cream devotee shared: 'This has to be one of my favourite products from Cosrx. As someone whose skin doesn't tolerate retinol, I have found this to be an amazing addition to my skincare routine. The blue colour is very unique, but thankfully it's clear when applied. The formula is very light and quick-drying. I didn't suffer any redness or irritation after use, and I have very sensitive skin.'
Comparison with Other Peptide Products
The COSRX launch enters a competitive market. Paula's Choice offers the Pro-Collagen Peptide Plumping Moisturiser (£49), praised for its quick absorption and lasting hydration. Medik8's Liquid Peptides Advanced MP (£79) has over 4,000 five-star reviews. One reviewer wrote: 'This peptide cream is amazing and is making such a difference to my skincare routine. Wouldn't be without it.'
With the new COSRX products priced under £30, they provide a more accessible entry point for those seeking peptide-based skincare. The brand's existing popularity, driven by the Snail Mucin Essence, suggests strong potential for the Blue Peptide line to become another staple in K-beauty routines.
