Peptides are chains of amino acids that act as the building blocks of proteins. They are a part of broader groups of biological polymers and oligomers.
This No7 serum contains a world-first super-peptide blend that harnesses the skin’s natural repair process. It was formulated using machine learning to identify naturally-occurring peptide sequences released by key skin molecules.
How Peptides Work
best peptides uk are a hot skincare ingredient that’s been getting lots of attention for its anti-aging properties. They can be used in serums or moisturizers since they tend to stay on the skin longer, which allows them to work their magic. They also mix well with other active ingredients, skincare chemists Gloria Lu and Victoria Fu of Chemist Confessions told Health.
Depending on what you’re looking for, some peptides can improve skin elasticity and smoothen out fine lines and wrinkles while others are more specific and target certain conditions. For example, telomerase inhibitor peptides slow down the aging process by protecting against cellular damage. Other peptides, like the growth hormone secretagogues ipamorelin and amlexanox/TTA, help increase your natural testosterone levels to support muscle growth.
If you choose to use a product with peptides, always apply the serum first before using creams or lotions because they can block absorption. And remember, peptides only work when they’re in contact with the skin for at least 20-30 minutes so make sure you use it consistently.
Peptides in Serums
Peptides are one of the latest buzzy skincare ingredients, and it’s not hard to see why. They can do everything from boost collagen production to soften the appearance of fine lines and wrinkles. Plus, they help improve skin hydration and even out the tone of your complexion.
The peptides found in serums are cell-communicative, meaning they signal your body’s cells to produce more collagen. This helps plump the skin and reduce the look of fine lines and wrinkles, while also enhancing elasticity and firmness.
The best peptide serums have multiple different peptide types, like copper-based peptides that help brighten the complexion and enzyme-inhibitor peptides that prevent the break-down of collagen. Some also have antimicrobial properties that kill the bacteria that cause acne. For those with oily skin, try a peptide serum that contains anti-inflammatory ingredients like bakuchiol or vitamin C. Meanwhile, dry skin will benefit from a rich formula with nourishing oils like shea butter or jojoba oil.
Peptides in Moisturisers
Every so often a new skin-care ingredient hits the headlines that claims to turn back time and leave our faces smooth, supple, plump and youthful. While some are more hype than action, others (like peptides) really do work.
While peptides can be found in face washes and serums, the best place to find them is in moisturizers, since these have thicker formulas that are designed to create a physical barrier that protects the skin from environmental aggressors. This one from Paula’s Choice combines a peptide complex with niacinamide, flower ferment filtrate and ume fruit extract to reduce puffiness, even skin tone and hydrate the complexion.
Peptides act as mini messengers, triggering certain responses in the skin cells to boost collagen production and improve skin texture. As a result, they help firm up fine lines and wrinkles, brighten dark spots, and promote skin healing. The one used in this serum is a novel synthetic tetra-peptide that has been optimised using robot technology and mathematical modelling techniques to penetrate the skin’s barriers and deliver the peptides where they are needed.
Peptides in Cleansers
Aiming to deliver the most effective results without disrupting skin’s natural barrier, this serum combines two synthetic peptides with a powerful botanical blend. The peptides enhance the expression of key proteins that support the skin’s natural self-repair function and improve its ability to naturally bounce back from damage and stress.
It also targets fine lines and wrinkles by relaxing muscles (similar to a Botox-like effect) and boosts collagen production for a plumper, firmer complexion. It also helps balance uneven skin tone and reduce the appearance of dark spots.
This serum is designed to penetrate deep into the skin’s tissues to deliver a highly potent cocktail of peptides that target ageing at multiple levels and boost collagen. It combines three powerful ingredients (palmitate of the peptide pal-GPKG, pal-LSVD and melon extract) with an innovative delivery system to optimise the penetration of peptides across different layers of the skin. It has also been optimised for ingredient stability and to work well with other hard-working active ingredients, like antioxidants and Hyaluronic Acid.
