Which ingredient is primarily used to reduce inflammation in skin care?

Niacinamide is recognized for its ability to significantly reduce inflammation in skincare. It is a form of vitamin B3 that has been shown to stabilize the skin's barrier function and enhance its resilience. This ingredient works by inhibiting the release of inflammatory cytokines, leading to a visible reduction in redness and irritation while promoting an overall even skin tone. Moreover, niacinamide has additional benefits, such as improving skin hydration, enhancing elasticity, and minimizing the appearance of enlarged pores, which further supports its role as a soothing agent.

In contrast, tretinoin is primarily used for its ability to accelerate skin cell turnover and treat conditions such as acne and photodamage, but it can sometimes cause initial irritation or redness. Ceramides are essential for maintaining the skin’s moisture barrier and preventing dryness, but they are not primarily anti-inflammatory; rather, they support overall skin health and stability. Hydroquinone is mainly used for its skin-lightening properties and is not regarded for its inflammatory benefits.
