PRINCIPLES OF SKIN MEASUREMENTS AND CLAIMS 2026
The intensive two-day programme in skin measurement sciences and claims

The skin is the largest and fastest-growing organ in our bodies. Its water barrier properties are vital for our very survival, and its overall condition and appearance are essential to our health and well being. It isn’t a surprise then that the skin care is the largest category in the cosmetics and personal care industry. The Principles of Skin Measurement Science & Claims course at TRI is designed for anyone involved in the development of new skin care products. The intensive two-day program is designed for anyone who needs to build their knowledge rapidly in skin biology, the measurement techniques used in the development of new skin products, and best practice in claim substantiation and experimental design.
