Peptides For Skin

What advantages come with peptide use in skincare products?

• Encourage Collagen Production: Since collagen is composed of three polypeptide chains, you can encourage your skin to produce collagen by using peptides. More collagen can make skin appear firmer and younger.
• Enhance Skin Barrier: The body’s first line of defense against germs, UV radiation, pollutants, and other toxins is the skin barrier, which peptides assist in strengthening.
• Reduce Wrinkles: Collagen helps make lips and skin more plump. Wrinkles and fine lines will be less noticeable in skin that is plumper and firmer.
• More Skin Elasticity: In addition to collagen, peptides also make up elastin fibers, another type of protein. These fibers make skin look firmer and tauter.
• Ease Inflammation: Peptides can help ease inflammation, repair damaged skin, and even out skin tone.
• Clear Breakouts: Some peptides are antimicrobial, meaning they can kill bacteria that cause acne.

Are peptides suitable for all skin types?

Yes, peptides are generally considered to be non-irritating and can be well-tolerated by all skin types, including sensitive skin. They are great for all skin types, especially for those who are dry to mature and notice increased fine lines and wrinkles and a loss in firmness. 

Are there any peptides made especially to target hyperpigmentation or dark spots?

Yes, there are peptides called inhibitor peptides that can be quite helpful in treating skin diseases that cause excessive pigmentation. The pigment known as melanin, which determines the color of your skin, hair, and eyes, can be inhibited by these peptides. 

Do peptides penetrate deeper layers of the skin compared to other ingredients like hyaluronic acid or glycolic acid?

Yes, peptides are known to penetrate the outer layer of the skin and sink in more deeply. They are essentially smaller versions of proteins, typically comprising 2–50 amino acids, which are the necessary building blocks of proteins. Because they are smaller, peptides are easier for the body to absorb than proteins and can more easily penetrate the skin and intestines, which helps them enter the bloodstream more quickly.

On the other hand, hyaluronic acid is a carbohydrate molecule that is naturally found in the skin. It helps to keep the skin hydrated and plump and is a key component of healthy skin. Hyaluronic acid is known for its ability to attract and retain moisture.

As for glycolic acid, it is a type of alpha-hydroxy acid (AHA) that is often used in skincare products for its exfoliating properties. It works on the surface of the skin, helping to remove dead skin cells and reveal the newer, brighter layers underneath.

Clinical studies supporting the effectiveness of peptides in skincare

A 14-week study of a peptide therapy serum targeted to repair aging face skin found considerable improvement in facial and eye lines/wrinkles at rest, as well as maximum smile by week 14 [1].

Another study showed that some peptides have the ability to destroy acne-causing bacteria because of their antimicrobial properties [2].

Based on different intracellular mechanisms, bioactive peptides have been shown in numerous in vitro/in vivo studies and clinical trials to be effective in improving skin appearance in topical applications and oral administration. These effects include improved skin whitening and moisturizing and a reduction in skin aging [3].

After 12 weeks of use, an IRB-approved clinical trial showing that LTPS was beneficial in alleviating expression lines, wrinkles, and skin health was completed. The study was randomized, double-blind, placebo-controlled [4].
