NIACIN

Description

Niacin, also known as vitamin B3 or nicotinic acid, is a vital nutrient with significant benefits for skin health and overall well-being. This water-soluble vitamin plays a crucial role in cellular metabolism and energy production. In skincare formulations, niacin is often used in its derivative forms, such as niacinamide or nicotinamide.

Topically applied niacin has been shown to improve skin barrier function, reduce transepidermal water loss, and increase ceramide production. These effects contribute to improved skin hydration and a strengthened protective barrier. Niacin also demonstrates anti-inflammatory properties, making it beneficial for conditions like acne and rosacea.

One of niacin's most notable attributes is its ability to stimulate collagen production, which can help reduce the appearance of fine lines and wrinkles. Additionally, it has been found to inhibit melanosome transfer to keratinocytes, potentially aiding in the reduction of hyperpigmentation and evening out skin tone.

In skincare products, niacin is typically used at concentrations between 2-5%. It is generally well-tolerated by most skin types, though some individuals may experience temporary flushing or redness, particularly with higher concentrations or pure niacin formulations.
