Byoma's new Longevit-8 Peptide Serum made our tester's skin look smoother and brighter, according to a review published by Metro. The serum, which launched in September 2026, is the brand's first dedicated anti-ageing product and costs £21.99.
What's in the serum?
The formula is rich in peptides, Phyto-PDRN, a Tri-Ceramide Complex, and nicotinamide mononucleotide (NMN). It is designed to help optimise the skin's natural ability to repair itself, and claims to boost collagen protection, hydration, radiance, and elasticity, while reducing redness, improving the appearance of wrinkles, and refining skin texture in as little as two weeks.
At £21.99, it is Byoma's most expensive product yet. It was created to build skin resilience for long-term health rather than overload the complexion with exfoliating acids, and suits all skin types.
The tester's verdict
The reviewer noted the serum is a gel that absorbs quickly with no pilling when applied to a clean, dry face beneath moisturiser. They did not wake up looking a decade younger, but observed a subtle plumping effect and smoothness to areas of texture, particularly around the chin where they get hormonal breakouts.
As someone with hormonal acne and rosacea, the reviewer said the serum did not irritate their skin. They described the packaging as undeniably pretty, with a metallic blue finish, and concluded it is not a miracle in a bottle but an easy, affordable way to add peptides to a routine while prioritising barrier support.
