While they might not be as renowned as retinol or AHAs, peptides have been making a big noise in the beauty industry and are considered one of the best anti-aging ingredients. The buzz is largely about their ability to reduce fine lines and wrinkles, but they can also improve skin texture and brighten dark circles around the eyes. The peptides in these products are made from chains of amino acids, which are the building blocks of proteins and are similar to the ones our bodies naturally produce. Lab-made peptides can mimic some of these and have been shown to have benefits for the skin, muscles, and even weight loss. It is thought they work by triggering the production of specific hormones and chemicals in the body that have positive effects on the skin.

While Jennifer Aniston’s weekly peptide injections are all the rage, topical versions are just as effective. They can help to boost collagen and increase the rate of cell turnover, giving skin a plumper appearance. In fact, a recent study found that using a topical peptide treatment twice a day increased skin elasticity by up to 30%.

When choosing the best peptides for your skin, look for products that include premium ingredients in their formulation. Ideally, these should be cruelty-free and free of synthetic fragrances and parabens. These are often used in beauty products as preservatives and can cause a reaction in some people. A good peptide serum should also be lightweight, non-sticky and hydrating. It should also have a high concentration of peptides to be effective. For example, Medik8’s peptide serum contains drone copper peptides to target damaged cells and super signalling peptide Matrixyl 3000 to reduce fine lines and wrinkles.

Another option is the vegan serum from Youth To The People, which features polypeptide 121 to boost collagen and hyaluronic acid for plumper skin. It also contains ceramides and plant-based superfoods to help smooth and hydrate the complexion.

If you are interested in purchasing peptides for the first time, it is wise to research the market before investing. This is because some peptides may not be bioactive, meaning that they are ineffective or break down during the digestion process. Moreover, they might not be as safe as others. Therefore, it is advisable to opt for a trusted and reliable online peptide supplier. The best peptides are those that come from a reputable source, are tested for purity and are sold with detailed instructions. Among the most reputable peptide vendors in the UK is Core Peptides, which offers more than 78 different products.

Peptides can work well with other actives, including AHAs and retinol. However, it is best to avoid mixing them with ingredients that have a tendency to irritate the skin. For instance, combining them with retinol can lead to redness and irritation. If you are unsure about the compatibility of your skincare with peptides, consult a dermatologist for advice. This will speed up the process of finding a product that works for you. best peptides uk
