Science & Key Ingredients.

Interface uses seven different bioactive peptides, including five unique types of peptides called growth factors.

Peptides work as messengers to tell the body to produce more of something. When your skin is injured, your body will naturally break down proteins from the extracellular matrix to create its own signaling peptides, telling your skin to produce more of certain types of proteins to heal or strengthen the skin.

Growth factors are found throughout the body; they bind to special receptors on a cell to regulate cell division, creation, and differentiation.

Here’s a breakdown of each peptide in Interface:

• Copper Palmitoyl Heptapeptide-14: stimulates production of collagen and elastin, which are responsible for skin’s firmness and elasticity

• Heptapeptide-15 Palmitate: targets fibroblasts, the dermal cells that generate collagen and elastin (part of a targeting encapsulation system for Copper Palmitoyl Heptapeptide-14)

• Sh-Oligopeptide-1: also known as Epidermal Growth Factor, it stimulates growth of skin cells in the epidermis to strengthen the skin

• Sh-Oligopeptide-2: a growth factor that promotes cell proliferation and wound healing

• Sh-Polypeptide-1 and Sh-Polypeptide-11: the two growth factor peptides that stimulate the growth and proliferation of fibroblasts, the dermal cells that make collagen

• Sh-Polypeptide-9: also known as Vascular Endothelial Growth Factor, it promotes the growth of capillaries to bring nutrients to the dermis

Interface is vegan and cruelty-free. All Stratia products are free of common irritants like fragrance, alcohol, and essential oils.


Apply twice daily for healthy, youthful skin

Can Interface be used with other actives like AHAs and retinol?

Yes! You can safely use Interface with all other skincare products. While copper peptides on their own can be unstable or reactive, our copper peptides are encapsulated in a two-layer biopolymer that protects them from interaction with other ingredients.

What's the difference between Interface and Liquid Gold?

Interface is a highly moisturizing gel-cream that firms, plumps, and strengthens the skin. It's a long-term investment in your skin's health. Liquid Gold is a serum-like lotion that quickly and effectively repairs damaged moisture barriers. It's like first aid for irritated skin.

I see glycolic and lactic acid in the ingredients list - will it irritate my skin?

The glycolic and lactic acid in the formula appear in tiny percentages, and are used as part of the encapsulation vehicle made of a glycolic/lactic copolymer. There's no exfoliation or irritation to worry about.

Is Interface vegan?

Yes! Interface is 100% vegan. All Stratia products are also cruelty-free and Leaping Bunny certified.
