Dipeptide diaminobutyroyl benzylamide diacetate is a tripeptide (a three amino acid peptide) with molecular weight less than 500 Da, meaning that it's small enough to penetrate nicely and easily into the skin.

Another peptide, unrelated to collagen synthesis and degradation, was formulated into the line treatment to target neuromuscular activity. Dipeptide diaminobutyroyl benzylamide diacetate was developed to mimic Waglerin-1, a compound found in temple viper snake venom. Waglerin-1 has been shown to block the nicotinic acetylcholine receptors at the neuromuscular junction, thus inhibiting muscular movement. The function of the Wagerlin-1-mimicking peptide is important for the treatment of lines since facial areas associated with repeated muscle movement are especially susceptible to wrinkle formation.
