This varies wildly. Some, like Fenty Skin, are developed with reputable chemists and contain effective ingredients. Others rely more on the celebrity name. Always evaluate the ingredient list and clinical data rather than the face behind the brand.
Extend your facial skincare products (serum, moisturizer, and especially sunscreen) down to your neck and décolletage every day, as this skin is also thin and prone to sun damage.
Skipping daily sunscreen. Tanning, whether outside or in beds, causes irreversible damage that accumulates over time and will show up as wrinkles, sun spots, and leathery texture later in life.
Consistent sun protection beyond the face—including the neck, chest, and hands. These areas are frequently exposed to UV radiation but often neglected, leading to visible signs of aging.
