Nicotinamide

Description

Nicotinamide, also known as niacinamide or vitamin B3, is a potent and versatile skincare ingredient with a wide range of benefits. This water-soluble vitamin is well-tolerated by most skin types and can be incorporated into various skincare formulations. Nicotinamide works at the cellular level to improve skin function and appearance.

Key benefits of nicotinamide include its ability to strengthen the skin barrier, regulate sebum production, and improve skin hydration. It has been shown to reduce transepidermal water loss, leading to improved skin moisture retention. Nicotinamide also exhibits anti-inflammatory properties, making it effective in managing acne and rosacea.

Research indicates that nicotinamide can stimulate collagen production and increase ceramide synthesis, contributing to improved skin elasticity and reduced fine lines. It has demonstrated effectiveness in lightening hyperpigmentation by inhibiting melanosome transfer to keratinocytes. Additionally, nicotinamide has antioxidant properties that help protect the skin from environmental stressors and may aid in preventing photoaging.

Typical concentrations in skincare products range from 2% to 5%, with some formulations containing up to 10% for targeted treatments. Nicotinamide can be combined with other active ingredients to enhance overall skincare efficacy.
