A dermatologist reveals her favourite peptide skincare products for your skin
Peptides are among the most talked-about ingredients on skincare labels in 2026. Yet many consumers still aren’t sure what they actually do for the skin. Peptide beauty products can strengthen the skin barrier, stimulate collagen production and reduce redness, according to several board-certified dermatologists.
What peptides are and why dermatologists love them
Peptides are, according to Dr Susan Massick, a board-certified dermatologist at Ohio State University, short chains of amino acids. Amino acids are the building blocks of proteins. As such, peptides send signals to skin cells to carry out specific functions, such as boosting collagen production, improving elasticity and reducing inflammation, explains Dr Angela Lamb.
Studies have shown that peptides can help repair the skin barrier or stimulate collagen production when used in certain formulations. Some peptides also display anti-inflammatory properties, according to a 2018 study. That said, the science is still relatively new and there is no long-term evidence of their anti-ageing effects.
Dr Massick notes that peptides are very safe to use. Unlike other active ingredients, they generally do not irritate the skin. As a result, they are suitable for all skin types, including sensitive skin.
How to choose the right peptide skincare
Dr Massick recommends opting for creams and serums over cleansers. Rinse-off formulas don’t have enough contact time to penetrate the skin. Peptide beauty products in serum or cream form therefore deliver better results.
When choosing a product, it’s worth checking the other ingredients in the formula. Peptides work synergistically with vitamin C, hyaluronic acid and niacinamide. Dr Massick also stresses the importance of adequate sun protection as part of any skincare routine.

Expert-recommended formulas for the face
Dr Lamb highlights a multitasking serum in which copper tri-peptides are key to collagen formation. Used twice daily, it hydrates, reduces the appearance of fine lines and stimulates collagen in a single step, making it one of the most versatile peptide beauty products in her view.
The Medicube PDRN Pink Peptide toner was named best toner by editors for its ability to address dark spots and signs of ageing while leaving a visible glow. Meanwhile, the Peptide Collagen Booster Toner Serum contains six types of peptides and targets pore size, skin texture and sebum control. Customers particularly recommend it for acne-prone or oily skin.
For the eye contour area, the thinnest skin on the face, the Lancer Eye Contour Lifting Cream combines hydrating, firming and depuffing ingredients. The formula is rounded out with diamond powder and minerals for a subtle luminosity. The Summer Fridays eye cream, enriched with vitamin C, is also a favourite among several members of the editorial team for its action on fine lines.
- Opt for serums and creams rather than cleansers for better peptide absorption.
- Look for synergistic ingredients such as vitamin C, hyaluronic acid or niacinamide.
- Start by patch-testing the product on a small area to check for any reaction.
- Pair peptide skincare with a mineral sunscreen to preserve results.
- Don’t expect a total anti-ageing overhaul: peptides primarily hydrate, nourish and support the skin barrier.
Peptide treatments for lips and lashes
The Rhode Peptide Lip Treatment is considered a benchmark in peptide-based lip care. Both the tinted and classic versions apply with a glossy finish and no stickiness. The RoC Derm Correxion Lip Volumizer, meanwhile, promises to smooth fine lines in three minutes and deliver a lasting plumping effect within four weeks, according to the brand.
The Kosas Soulgazer Lengthening Mascara + Lash Serum incorporates a unique peptide serum. It lengthens without smudging and promises longer, fuller lashes in six to eight weeks. Wearing this mascara, then, doubles as a daily lash treatment.
Peptide skincare for the neck, hair and nails
Peptide beauty products aren’t limited to the face. Dr Lamb recommends a peptide protein neck cream to stimulate collagen production and combat crepey skin. The formula also contains green tea and vitamin B5 to target sun damage and hyperpigmentation.
For hair, The Ordinary Multi-Peptide Serum for Hair Density contains several peptide complexes designed to promote a healthy scalp environment and strengthen hair follicle vitality. Dr Lamb notes it’s a strong option for those noticing the first signs of thinning, as peptides signal follicles to increase hair growth.
Nails need hydration too. Signs of dryness such as brittle, cracked or peeling nails can be addressed with a peptide cuticle serum. The HydroPeptide Solar Defense Tinted SPF 30, meanwhile, protects skin from UVA, UVB and infrared rays while delivering extra hydration thanks to the peptides in its formula. Dermatologists remind us that mineral sunscreens containing zinc oxide create a physical barrier between skin and UV rays. Peptide beauty products can therefore be incorporated into every step of a complete routine, from morning to night.
