Detailed answer

Niacinamide and arbutin are both effective ingredients for improving uneven texture and brightening the skin. Niacinamide helps to regulate sebum production, reduces inflammation, and improves skin elasticity, while arbutin inhibits the production of melanin, which can help lighten dark spots and hyperpigmentation. When used together in a serum, they can work synergistically to even out the skin's texture and promote a brighter complexion. It's important to note that individual results may vary, so it's always a good idea to patch test the serum before applying it to your entire face. Additionally, make sure to follow the recommended usage instructions and incorporate it into your skincare routine appropriately to maximize its benefits.
