Niacinamide isn’t just beneficial for younger skin burdened by acne, it also has benefits for more mature skin. There’s some evidence that it stimulates cells in the dermis to produce more collagen, a protein that supports skin and gives it its youthful firmness. That’s a good thing since collagen levels decline with age, and loss of collagen is a major cause of wrinkles and saggy skin. It’s also helpful for treating another problem that’s common with mature skin – excessive dryness. According to one study, niacinamide was more effective for preventing moisture loss and dryness than petrolatum, a moisturizing ingredient that creates a tight, occlusive barrier against loss of water. Although effective, petrolatum is a by-product of petroleum, and many people want to avoid petroleum products. It also has a heavy, greasy feel, while niacinamide doesn’t.

There’s another way niacinamide improves dry skin. It increases the production of ceramides, lipids in the outer layer of the epidermis that shield skin against moisture loss and protect it from bacteria and the environment. Ceramides, along with other lipids like cholesterol and fatty acids, form a protective barrier against water loss, so replacing ceramides lost through aging and the use of harsh cleansing products helps to keep skin moist and supple.
Another skin problem that goes along with aging is increased skin pigmentation. It’s common for people with more mature skin to complain of age spots and patchy areas of increased pigmentation from years of sun exposure. Niacinamide in concentrations of 4% helps to lighten areas of pigmentation and age spots. It also reduces blotchiness and evens out skin tone while improving skin texture. From treating dry skin to wrinkles, pigmentation and acne breakouts, niacinamide offers a variety of skin benefits.
