Article Overview
- Peptides are made up of small amino acid chains that make up the building blocks of essential proteins in the body. They have the ability to signal to, transport or inhibit certain enzymes (depending on the type), and play a key role in protecting and strengthening the skin.
- Though naturally occurring, synthetic peptides are available in the form of supplements and skincare formulas, and are beneficial in addressing skin elasticity, fine lines and wrinkles, skin texture and skin tone.
WHAT ARE PEPTIDES?
Peptides are fragmented versions of proteins found in every cell of the body. They’re made up of very short chains of amino acids (around 2 to 50) linked by peptide bonds. These amino acids are the building blocks of several different proteins found within the skin, including keratin, collagen and elastin. Peptides have a very small molecular weight which gives them the ability to penetrate deeper layers of the skin to signal to, inhibit, protect against and transport enzymes to different parts of the body.
WHAT ARE THE DIFFERENT TYPES OF PEPTIDES?
Peptides fall under four main categories: signal peptides, carrier peptides, neuropeptides, and enzyme inhibitor peptides.
Signal peptides
Signal peptides work by triggering skin fibroblasts to promote the production of collagen and elastin production. The new collagen and elastin helps maintain the skin’s elasticity. Most peptides in skincare, namely collagen and copper peptides, are signal peptides.
Carrier peptides
Carrier peptides deliver specific enzymes to deeper layers of the skin for better absorption. Because of their lower molecular weight they can penetrate the skin deeper than larger molecules.
Neuropeptides
Some wrinkles and lines are caused by the regular contraction of muscles that leads to expression lines. Neuropeptides work within the muscles that contribute to these lines.
Enzyme inhibitor peptides
This type of peptide can inhibit enzymes that break down existing collagen and other proteins to slow down the process of skin ageing.
BENEFITS OF PEPTIDES IN SKINCARE
Peptides have a number of skincare benefits thanks to their ability to promote collagen production and provide antioxidant protection. The main benefits of peptides for skin include:
- Promotes collagen production:As we age, our natural collagen production declines, and peptides can counteract this decline by promoting more collagen production to address various ageing skin concerns, including fine lines and wrinkles, skin texture, and skin firmness.
- Strengthens the skin moisture barrier: A stronger moisture barrier helps to keep the skin hydrated while protecting against environmental aggressors.
- Minimise visible redness: Some peptides can help to reduce and neutralise skin redness for a more even skin tone.
- Enhanced hydration: Peptides can improve the skin's ability to retain moisture, leading to better hydration and a plumper, more youthful appearance.
- Speeds up skin cell turnover: Peptides can signal to the body to speed up the skin cell renewal process to reveal fresher, more radiant skin.
- Antioxidant properties: Antioxidant peptides help neutralise free radicals from the environment, which can help prevent premature ageing.
- Evens out skin tone: Peptides can help to even out skin tone by reducing hyperpigmentation and promoting an even complexion.
- Increased elasticity: By triggering collagen and elastin production, peptides can improve the skin's firmness and elasticity, making the skin less prone to sagging.
- Helps absorb other products: Peptides can enhance the efficacy of other skincare ingredients by improving their absorption and penetration into the skin.
HOW ARE PEPTIDES USED IN SKINCARE?
Peptides are very versatile and come in a variety of formulations, so you can easily incorporate them into your routine. You'll find peptides in creams, moisturisers, serums, toners and some cleansers.
HOW TO USE PEPTIDES
Here are our top tips for adding peptides to your daily skincare routine.
- Find the right product: There are different concentrations, types and formulations available, so make sure you're choosing the right product for your skin type and skin concerns.
- Choose the right peptide formula: Different peptides can have different properties, so make sure you choose the right formula. For skin elasticity, look to collagen peptides. For fine lines, wrinkles and uneven skin tone, copper peptides are the best option.
- Combine with complementary skincare products: Because peptides can improve the absorption of other products, peptides are great for combining with other active ingredients. Depending on your skin goals, you can benefit from combining peptides with hyaluronic acid, retinol, niacinamide or vitamin C.
- Gradually introduce the product: Peptides are suitable for most skin types but your skin needs time to adjust to any new product. Start using your peptide product 1-2 times a week and gradually increase to daily or twice daily, depending on the formula.
- Patch test: Similarly, make sure to patch test any product and notice how your skin responds before adding it to your regular routine. If you notice skin irritation, stop using the product.
- Be consistent: Peptides won't show instant results, as they penetrate deeper layers of the skin and require consistent use. Consistent use will show gradual improvements over time.
WHICH INGREDIENTS CAN BE USED WITH PEPTIDES?
Peptides are especially useful in enhancing the skin benefits of other ingredients as they can improve product absorption. The best ingredients to combine with peptides.
- Retinol: Helps speed up skin cell turnover to enhance the anti-ageing skin benefits of peptides.
- Vitamin C: Combine vitamin C and peptides to boost their antioxidant properties protecting the skin against environmental aggressors.
- Niacinamide: Helps with hyperpigmentation by targeting the pigment cells responsible for dark spots. When combined, the two can target age spots and uneven skin tone, while also strengthening the skin moisture barrier.
- Hyaluronic acid: Keeps skin hydrated for skin plumpness and smoother skin texture.
- Ceramides: Help strengthen the skin moisture barrier so peptides can penetrate the skin.

WHAT ARE THE SIDE EFFECTS OF PEPTIDES?
Peptides are generally suitable for most skin types, but some people may experience skin sensitivity, irritation and, in rare cases, a possible allergic reaction. If you notice skin irritation, stop using the product..
Some peptide formulas can also be comedogenic that can clog pores and lead to breakouts. If you have blemish-prone or oily skin look for a lightweight, non comedogenic peptide formula. .
