KEY INGREDIENTS
Arginine - A semi-essential amino acid that is one of the primary building blocks of hair keratin and skin collagen. It's a natural moisturizing factor, a skin hydrator and might also help to speed up wound healing. Arginine usually has a positive charge (cationic) that makes it substantive to skin and hair (those are more negatively charged surfaces) and an excellent film former. Thanks to the positive charge, it also creates a complex with AHAs (AHAs like to lose a hydrogen ion and be negatively charged, so the positive and the negative ions atract each other) that causes a "time-release AHA effect" and reduces the irritation associated with AHAs.
Calendula Officinalis - The extract coming from the popular garden plant Calendula or Marigold. It's used traditionally as a skin-repairing and soothing plant extract.
Butylene Glycol - Butylene glycol, or let's just call it BG, is a multi-tasking colorless, syrupy liquid. It is a great pick for creating a nice feeling product. BG's main job is usually to be solvent for the other ingredients. Other tasks include helping the product to absorb faster and deeper into the skin (penetration enhancer), making the product spread nicely over the skin (slip agent), and attracting water (humectant) into the skin.
PVP - These three letters stand for Poly Vinyl Pyrollidone, a big molecule created from repeated units of Vinyl Pyrrolidone, aka VP. Its main thing is being an important film former. It was the first synthetic polymer introduced as a hair fixative in the 1950s instead of insect-derived Shellac. So PVP likes to attach itself to surfaces such as the hair and the skin and forms a nice, thin, even film there. The film is useful for holding a hairstyle or extending the wear of colour cosmetics and sunscreens.
