Building a Brightening Active Stack
Building a Brightening Active Stack — focuses on assembling ingredients that support a more even-looking tone and address the appearance of dark spots and dullness. Typical choices include vitamin C, niacinamide, and gentle exfoliating acids, anchored by consistent daytime sun protection. Because uneven tone often relates to sun exposure, sunscreen is central to the approach.
Key points
- Vitamin C is a popular daytime antioxidant associated with a brighter-looking complexion.
- Niacinamide is often included to support the appearance of an even tone and is generally well tolerated.
