Dealing with sensitive skin, or a particular condition like eczema or dematitis? “There are also anti-inflammatory peptides that can help to reduce inflammation, promote wound healing, and improve skin hydration,” Dr Ifeoma adds.
Are there any drawbacks to peptides?
Most obviously — they’re typically pretty pricey. But why? “They can be challenging to formulate in cosmetic products as they do not penetrate easily into living epidermis, they have limited chemical stability, and they can be costly to produce,” explains Dr Mahto.
“Just be aware that with every new ingredient that comes onto the market, we do not always have the answers regarding its true efficacy,” Dr Mahto adds. “The most trusted solution for tackling ageing skin is still applying sunscreen in the morning, and a retinoid product at night — both of which have plenty of evidence regarding their benefit.”
Another key thing to bear in mind about peptides is that they certainly aren’t a solution for the ageing process. In other words, don’t fall for the trap of thinking a peptide serum will give you the same results as a round of botox. “It’s definitely important to note that peptides are not a miracle solution, and should be used in conjunction with other skincare products and lifestyle habits for optimal results,” Dr Ejikeme adds.
What skin types should use peptides?
In short — all! According to Dr Bradley, you don’t need to have a specific skincare concern to use peptides. “Peptides are a great ingredient to use to start working against damage that you are unable to see or hasn’t come up to the surface yet,” he explains. “All skin types should incorporate them into routines to help future proof skin.”
And according to Dr Ejikeme, peptides generally pair well with most other skincare ingredients. “Especially antioxidants like vitamins C and E, hyaluronic acid for hydration, and retinoids for their anti-aging benefits,” she adds.
How can you incorporate peptides into your skincare routine?
In terms of product format, peptide serums are likely your best bet, as they’re more lightweight, and have been designed to penetrate deeply into the skin — meaning you can expect maximum absorption. Creams also work well, as well as other leave-on formats like boosters and eye creams.
It’s best to layer your skincare products from thinnest to thickest — so pop your peptide serum on after any water-based serums (eg hyaluronic acid), and before any moisturisers or face oils. “Apply your serum once in the morning on a cleansed face before your moisturiser and SPF, and once at night after cleansing and before using any moisturiser,” says Dr Bradley.
What are some of the most common peptides found in skincare products?
“Different types of peptides have different effects — from smoothing wrinkles and repairing function, to increasing firmness and hydration,” explains Dr Bradley. “And you’ll typically find several different peptides combined in one product.”
In terms of specific types, palmitoyl peptides are widely respected for their collagen stimulating abilities, while Argireline — also known as Acetyl Hexapeptide-8 — can help to smooth over fine lines, and relax the facial muscles. Meanwhile, natural antimicrobial peptides like lysine help to kill the bacteria that causes breakouts and acne, and even out the skin tone of those suffering with eczema — while also promoting smoothness, softness, and overall skin health.
