Peptide serums can firm, smooth and hydrate—here’s how they work

Choosing the right peptide serum means understanding what your skin actually needs and checking the ingredient list accordingly.

The peptide serums to try

COSRX The 6 Peptide Skin Booster

This peptide serum packs six targeted peptides—including Copper Tripeptide-1 and Acetyl Hexapeptide-8—alongside hyaluronic acid and amino acids to support hydration, firmness and skin tone. Designed as a serum-booster, it helps reduce visible signs of ageing while promoting a smoother, more even complexion. A solid entry point for anyone looking to build peptides into their routine.

The Ordinary Multi-Peptide + Copper Peptides 1%

A cult-favourite in the world of peptide serums, this formula combines multiple peptides, amino acids and hyaluronic acid to address fine lines, loss of firmness and dullness. The addition of copper peptides helps support skin renewal and enhances radiance, making it a go-to for improving overall texture and tone. Expect skin that feels firmer, smoother and more resilient over time.

Lancôme Rénergie HCF Triple Serum

Backed by decades of research, this high-tech peptide serum features SNK-enhanced peptide—a tripeptide shown in vitro to help reduce muscle cell contraction. The result is visibly firmer skin and a softening of dynamic wrinkles, particularly around areas prone to expression lines. It also targets uneven skin tone, making it a comprehensive option for more advanced signs of ageing.

Paula’s Choice Pro-Collagen Multi-Peptide Booster

This lightweight yet nourishing peptide serum is powered by six pro-collagen peptides that work to firm, smooth and support skin structure. Hyaluronic acid boosts hydration, while hydrolysed yeast extract helps reinforce the skin barrier. Suitable for all skin types, it targets both early and established signs of ageing, with visible improvements in elasticity and fine lines over time.

FCL Copper Peptide Serum

Formulated to tackle multiple concerns—dark spots, fine lines and dullness—this copper peptide serum supports collagen production while helping to brighten uneven skin tone. It also works to calm inflammation, strengthen the skin barrier and improve hydration, making it a well-rounded option for anyone dealing with both pigmentation and early signs of ageing. With regular use, skin looks clearer, smoother and more even.
