Niacinamide (Vitamin B3) is a powerful skin care ingredient that yields many benefits. Below are the various benefits proven in independent studies involving niacinamide.
Strengthening Skin Barrier Function
Niacinamide strengthens epidermal barrier function by improving moisture content (reducing transepidermal water loss), increasing protein synthesis (keratin), and stimulating ceramide synthesis.
Due to this unique benefit of enhancing barrier function, niacinamide would be an ideal ingredient for those suffering from epidermal barrier function disorders and inflammatory disorders like rosacea and acne.
Reducing Sebum Production
A study revealed that 2% niacinamide may be an effective treatment for reducing sebum secretion.
Niacinamide can benefit individuals with acne by reducing inflammation through epidermal barrier enhancement. A study revealed that a 4% concentration is comparable to 1% clindamycin (topical antibiotic) in the treatment of acne. Additionally, niacinamide does not contain any risk for producing bacterial resistance.
Reducing Fine lines and Wrinkles
The skin lightening mechanism of niacinamide is through the suppression of melanosome transfer. Disrupting the transfer of melanocytes to keratinocytes effectively treats various pigmentation issues such as dark spots, acne marks, and age spots.
Niacinamide has been shown to have profound skin lightening effects at 5%.
Reducing Yellowing Of The Skin
Niacinamide has been shown in a study to combat yellowing of the skin (due to age, environmental factors etc.).
Niacinamide is what I like to call an ‘elite’ skin care ingredient. Its benefits are abundant, and incorporating a niacinamide based product within any skin care regimen is beyond beneficial.
