What are amino acids?
Why apply amino acids to the skin?
When you apply the essential (and non-essential) amino acids to the skin, it has been shown in multiple studies to have significant effects, ranging fromantioxidant and boosted UV protection (Journal of Photochemistry and Photobiology, 1999), to the promotion of tissue repair (Journal of Clinical Investigation, 1993), to conditioning the skin (Conditioning Agents for Hair and Skin [book], 1999).

Which amino acid skin care products to use first?
The reason? More hydrating agents create a thicker barrier, so it can be difficult for other skin care creams to reach the skin afterwards.
You should be able to feel which cream or moisturizer is the heaviest.
