Application Note
MoistureMeterEpiD measuring the moisturizing effect of hyaluronic acid
Hyaluronic acid (HA) is known to be a moisturizing ingredient in skin care products. Skin hydration is an essential parameter when measuring the moisturizing effect of the product. The MoistureMeterEpiD manufactured by Delfin Technologies is excellent choice when measuring skin deep hydration. It measures total water content of the tissue down to epidermal layer of the skin by using sensitive capacitive technique.
HA is widely used in cosmetics and especially when anti-aging is in question. HA is a normal component of the skin but it decreases with the increase of age which causes signs of skin aging. Ferrillo et al. investigated the efficacy of anti-aging products including HA combined with other compounds. The hydration change in epidermis was measured with the MoistureMeterEpiD and increase in skin deep hydration was found after the use of topical products.
The authors emphasized the importance of the instrumental based methods when analyzing the product efficacy.
Wu et al. applied the MoistureMeterEpiD to measure skin hydration after hyaluronic acid gel treatment on hands and showed statistically significant improvement in skin hydration. Based on their observations, the tissue water content was increased compared to the baseline even after 15 months after treatment.
The MoistureMeterEpiD provides an objective and accurate result for local deep skin hydration. It is applied worldwide in efficacy testing but also for example in skin care product development and marketing of skin care products.
