UNSTRESS is Christina neurocosmetics – a line designed for sensitive, couperose, and stressed skin. The name is not accidental: this line addresses skin stress on three levels: external (UV, smog, air conditioning), internal (cortisol, sleep deprivation), and mechanical (post-laser, post-workout micro-trauma).
Central idea: neuro-skin connection. Skin has its own peripheral nervous system that communicates with the brain via neuropeptides. Brain stress – skin stress. UNSTRESS supports this axis through cosmetic probiotics, calming plant extracts, and low-reactive formulas.
Second pillar: fighting inflammaging – chronic low-grade inflammation that accelerates skin aging. UNSTRESS soothes micro-inflammation daily, without aggressive actives.
Bacterial microflora + postbiotics – rebuilding the natural barrier and microbiome after stress.
Formulas supporting the brain-skin axis through soothing extracts and plant adaptogens.
Alleviating chronic micro-inflammation – prevention of stress-induced aging.
No alcohol, artificial fragrances, aggressive preservatives. Safe for reactive skin.
UNSTRESS is based on cosmetic probiotics, niacinamide, panthenol, and calming plant extracts.
