Bakuchiol, unlike retinoids, does not cause photosensitivity or act as a photosensitizing agent. Additionally, our serum contains skin-brightening ingredients like niacinamide and lactobionic acid, both of which have no contraindications in this context. Niacinamide is a vitamin that is perfectly compatible with sun exposure, and lactobionic acid is also gentle enough for use in sunlight due to its mild exfoliating action. We always recommend using sunscreen during the summer or in cases of direct sun exposure.
