Peptides are short chains of amino acid sequences. They have the ability to trigger cellular processes that stimulate collagen production.
Peptides evolved from research into wound healing and studies on growth stimulation from human skin fibroblasts. Wound healing studies on human keratinocytes cultures showed a stimulatory effect from topical application of peptides.
There are four types of peptides.
1. Signal Peptides
2. Neurotransmitter-inhibitor Peptides
3. Enzyme Inhibitor Peptides
4. Carrier Peptides

Peptides have been proven to be more effective than the gold standard prescription Vitamin A in the treatment of photoaging.
