Jack Black Protein Booster Skin Serum brings Camellia Sinensis Leaf Extract, Dipeptide Diaminobutyroyl Benzylamide Diacetate, and Retinyl Palmitate as actives, while dr. Idriss Major Fade Hyper Serum Dark Spot + Hyperpigmentation Treatment with Niacinamide and Glycerin relies on Niacinamide, Alpha-Arbutin, and Glycyrrhiza Glabra (Licorice) Root Extract. Both approaches have merit, but the positioning and supporting ingredients make the difference.
