Skin sensitivity
Skin sensitivity
Sensitive skin is a condition of hyperreactivity to environmental factors or topically applied products. Skin sensitivity is associated with disrupted skin barrier function, which causes increased transepidermal water loss (TEWL). It also allows penetration of irritants, environmental pollutants, or cosmetic products.
Sensitive skin can be characterized by a spectrum of symptoms and can be divided into 4 subtypes: acne type (prone to acne, blackheads, whiteheads), rosacea type (prone to redness, flushing and hot sensations), stinging type (tendency to burning or stinging sensations) and allergic type (prone to skin flaking, itching and erythema). But they all share one common factor, that is inflammation.
A protocol built for your claims.
Efficacy testing protocol is prepared for each product individually with close cooperation with the sponsor. Based on the claims, usage regime and efficacy expectations, we prepare a protocol that is suitable for the type of product and can confirm product efficacy. The studies can be performed over a different time period (from a few days to several weeks or months) depending on the claim and type of measurement.
