EGF, NAD+, and Peptides: What They Actually Do for Your Skin

Peptides: The Messengers

Peptides are short chains of amino acids — the building blocks of proteins like collagen. In skincare, specific peptides (like Palmitoyl Pentapeptide or Acetyl Hexapeptide, both found in our Deep Collagen Silk Peptide Ampoule) are used because they're thought to signal skin to support its own collagen production and hold onto moisture.

EGF: A Growth Factor Borrowed From Biology

EGF (epidermal growth factor) is a protein that occurs naturally in the body and plays a role in cell renewal. In skincare, it's included in small, cosmetic concentrations to support skin's natural repair processes over time — not as a medical treatment, but as a supporting ingredient in a broader routine.

NAD+: Cellular Support

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme involved in how cells produce energy. It's a newer addition to skincare formulas, often paired with peptides and growth factors in products aimed at supporting skin as it ages.

Putting It Together

None of these ingredients work in isolation, and none of them are overnight fixes. They're supporting actives in a formula — most effective when used consistently, alongside the basics: cleansing, hydration, and daily SPF.
