Peptides are small molecules comprised of several amino acid chain sequences, which like those in TriHex Technology, can have a lipid carrier to help them more easily absorb into the skin where they can support collagen and elastin and other important functions. They are synthetically derived and are not based on human and animal-derived materials. ALASTIN uses well defined peptides which are predictable, therefore we can anticipate their behavior because the amino acid sequence is well known and their function has been demonstrated and proven.
