Are Peptides the New Power Players in Beauty?

Once a niche ingredient reserved for advanced skincare formulations, peptides are now taking centre stage in the beauty industry. From high-performance serums designed to enhance in-clinic treatments to peptide-infused lip glosses championed by celebrities, these powerhouse molecules are fast becoming non-negotiables in any effective skincare routine.

But what exactly are peptides, and why are they so essential for healthy, youthful skin?

Renowned Harley Street cosmetic physician Dr Bibi Ghalaie, the new Global Ambassador for Medik8, breaks down everything you need to know about beauty's latest must-have ingredient.

Peptides are often called a skincare powerhouse. Why are they so important for skin health?

Peptides are the building blocks of collagen, elastin, and keratin, which are essential for skin elasticity, strength, and overall health. They hydrate the skin, reduce inflammation, stimulate collagen, brighten tone, and promote healing.

How do peptides compare to other popular anti-ageing ingredients like retinol or vitamin C?

Peptides act as messengers, telling cells to produce collagen and repair skin, making them great for fine lines and sensitive skin.

There are so many different types of peptides in skincare. What are the key ones we should look for, and what do they actually do?

Peptides can be categorised by function:

1. Signal peptides boost collagen and elastin for firmer skin and fewer wrinkles (e.g., Matrixyl 3000).
2. Carrier peptides help brighten, repair, and increase elasticity by delivering copper and magnesium.
3. Neurotransmitter-inhibiting peptides, like Argireline, reduce expression lines and wrinkles.
4. Antibacterial peptides, such as defensins, help with breakouts, redness, and acne-prone skin.
5. Enzyme-inhibiting peptides, like rice peptides, slow collagen and elastin breakdown, delaying ageing.
