Why can Niacinamide Skin Care Facial Essence enhance skin barrier function?

Importance of Ceramides: Niacinamide Skin Care Facial Serum contains ceramides, an important component of the skin barrier, which plays a vital role in maintaining the integrity and function of the skin barrier. Ceramide content in the stratum corneum of atopic dermatitis, elderly skin, and winter dry skin is significantly reduced, which leads to impaired skin barrier function.
The role of nicotinamide: Niacinamide enhances skin barrier function by increasing the content of ceramides in the stratum corneum. This enhancement helps reduce skin moisture loss and improves the skin's water-holding capacity, making the skin healthier and hydrated.
Repair damaged stratum corneum: Niacinamide has the ability to repair the lipid barrier of damaged stratum corneum, which helps restore the normal barrier function of the skin. Damaged stratum corneum can cause skin sensitivity and susceptibility to external irritation, and the repairing effect of nicotinamide can effectively alleviate these problems.
Improve defense ability: By enhancing the skin barrier function, nicotinamide also indirectly improves the skin's defense ability, making it more resistant to external environmental damage, such as ultraviolet rays, pollutants, etc.
Promote epidermal layer protein synthesis: Niacinamide can promote epidermal layer protein synthesis, which is the basis for maintaining and enhancing skin barrier function. Proteins are an important component of skin cells and play a key role in maintaining the structure and function of the skin.
Anti-aging effects: In addition to enhancing skin barrier function, niacinamide can also exert anti-aging effects by promoting protein synthesis. It can help the skin metabolize aging cells, reduce facial wrinkles, and make the skin plumper and firmer.
Reduce sebum secretion: Topical niacinamide can reduce the production of fatty acids and triglycerides in sebum, thereby helping to regulate sebum secretion. Moderate sebum secretion is beneficial to skin health, but excessive sebum secretion can lead to clogged pores, acne and other problems. The regulating effect of nicotinamide helps maintain the balance of sebum secretion.
Moisture-locking: Niacinamide also has the effect of deeply locking in moisture, which helps maintain the skin's moisture balance. Moisture is one of the important factors for skin health. Lack of moisture can lead to dry, rough skin and other problems. The moisture-locking and moisturizing effect of niacinamide helps keep the skin hydrated.
Niacinamide skin care facial essence enhances skin barrier function by increasing ceramide content, improving skin resistance, promoting protein synthesis, regulating sebum secretion, and deeply locking in moisture. This makes it a popular skin care ingredient, especially suitable for people who need to improve skin barrier function, enhance skin resistance and anti-aging.
