Ingredient
Lactic Acid (AHA)
Exfoliation that hydrates while it works.
Lactic acid is a larger AHA that exfoliates more gently than glycolic while drawing moisture like a humectant — the reason dermatology historically favors it for dry, sensitive skin.
Studies show lactic acid improves texture with a lower sting profile; Coyglow formulates it at 5% alongside sodium PCA.
How to use: Alternate evenings as your introductory acid.
Cautions: Mild flushing on very reactive skin is possible; buffer with mist.
