What are biomimetic peptides?

Find out more about this cutting-edge skincare ingredient.

Biomimetic peptides are synthetic peptides created in a laboratory to mimic naturally occurring peptides. ("Bio" means "life" and "mimetic" means "mimicking.") In skin care, biomimetic peptides are used in targeted treatments such as facial serums to reduce the appearance of aging.

What do peptides do for the skin?

Peptides are chemical messengers that tell our cells what to do. All peptides are made up of amino acids that are used by the skin to build proteins such as collagen, elastin and keratin. These substances are what hold the skin together and keep it firm. Peptides can also control factors that affect skin tone, sensitivity, hormonal activity and more.

Biomimetic peptides can be added to cosmetic formulas to achieve specific results such as wrinkle reduction, hydration or skin barrier restoration.

Does Dermalogica use biomimetic peptides?

Yes. One example is glutathione, which is modeled after the antioxidant peptide that occurs naturally in our bodies. Naturally occurring glutathione helps us fight and neutralize free radicals produced by external stressors such as UV radiation and pollution. However, this natural ability declines with age.

Biomimetic Glutathione helps to firm the skin and strengthen the skin's defenses against our exposome. You'll find this ingredient in Phyto-Nature Firming Serum, which is clinically proven to reawaken the nature of younger-looking skin.
