Peptides

…

Peptides are essential building blocks of proteins that keep the skin looking smooth, firm, and youthful. Applied topically, they can help to stimulate collagen and boost elasticity, visibly reducing the appearance of fine lines and wrinkles. Our innovative peptide skincare products feature expertly engineered peptide combinations for visible brightening, clarifying, and hydrating effects, delivering maximum results.

Frequently Asked Questions

Which types of peptides are most effective?

Peptides are a diverse group of active ingredients, each designed to target specific skin concerns. 

  • Signal peptides help stimulate collagen production, 
  • Carrier peptides support skin repair
  • Neurotransmitter peptides work to visibly soften the appearance of expression lines.

The most advanced formulations combine multiple peptide types to deliver comprehensive anti-ageing benefits and support overall skin renewal.

Liquid Peptides Advanced is Medik8’s next-generation peptide serum, formulated with a 30% multi-peptide blend and powered by Dual MiniProteins™ to visibly target both early and deep-set wrinkles.

Are peptides suitable for sensitive skin?
Yes, peptides are generally very well tolerated, even by sensitive skin. Their gentle nature makes them ideal for supporting skin that’s prone to irritation, as they help to calm, hydrate and reinforce the skin barrier. As with any new product, we recommend patch testing first, especially if your skin is reactive or compromised.
Can you use peptides when pregnant?

Peptides are generally considered safe to use during pregnancy. Unlike ingredients such as retinoids, peptides do not pose known risks and can continue to support the skin through hydration and repair. However, if you’re unsure, it’s always best to check with a healthcare provider.

Can you use peptides with retinol?

Peptides and retinol aren’t rivals, they’re complementary. While retinol encourages skin renewal and boosts collagen production, it can sometimes cause dryness or irritation, particularly for sensitive skin. Peptides, on the other hand, help to firm, smooth and support the skin barrier more gently.

Using both in a balanced routine can deliver powerful results. Peptides can help buffer the effects of retinol, making the combination ideal for visibly improving signs of ageing without compromising comfort. 

Medik8’s Crystal Retinal pairs well with Liquid Peptides in a balanced evening routine.

Which peptides are best for anti-ageing?

Different peptides target different signs of ageing, which is why combining them often delivers the most visible results. Signal peptides help stimulate collagen production, while neurotransmitter peptides visibly smooth expression lines. Carrier peptides support skin regeneration, and enzyme-inhibitor peptides help slow the breakdown of collagen and elastin.

Medik8’s Liquid Peptides Advanced features a 30% blend of 10 carefully selected peptides, including our pioneering Dual MiniProteins™. This next-generation formula is clinically proven to visibly reduce both expression lines and deeper wrinkles, offering comprehensive, targeted support for firmer, smoother-looking skin[1].
