condition background

Rosacea is a chronic inflammatory skin disorder characterised by persistent redness, visible capillaries, flushing, and in some cases papules and pustules. Though its exact cause is multifactorial, contributing factors include an impaired skin barrier, vascular hyperreactivity, an imbalance in the skin microbiome (notably Demodexmites), and heightened inflammatory responses, often worsened by environmental triggers and irritants in conventional skincare.

A major challenge in managing rosacea is finding active skincare that calms inflammation without disrupting the fragile epidermal barrier or overstimulating reactive skin.

why chitosan helps

Chitosan’s anti-inflammatory and antimicrobial properties are uniquely suited for rosacea prone skin. Its positive charge allows it to form a breathable, semi-occlusive film over the skin’s surface, protecting from environmental aggressors while enhancing hydration without clogging pores or exacerbating heat sensitivity.

Crucially, chitosan inhibits inflammatory enzymes and reduces oxidative stress, two central pathways in rosacea flare ups. Its gentle bioadhesive nature also allows it to act as a carrier for other calming ingredients like hyaluronic acid and cactus extract without sensitising the skin.
