Hey Reader!

​

Here’s what the science says:

1. Vitamin C (L‑ascorbic acid): A top antioxidant that neutralizes free radicals and inhibits tyrosinase—best when paired with E + Ferulic Acid.
2. Kojic acid: Gentle and effective in serums/creams; it inhibits the enzyme, prevents new spots, and fights free radicals.
3. Arbutin: A mild, all-skin-type favorite (beta- and alpha- forms). Dermatologists love its gentle tyrosinase inhibition.
4. Azelaic, tranexamic, phenylethyl resorcinols & more: Each slows the pigment-making process at different steps, so stacking similar products enhances results.
