Dia-Stron offers two different systems uniquely designed for skin evaluation, to measure characteristics such as elasticity, firmness and translucency.

The Torsional Ballistometer (BLS780) instrument’s principle is based on an impact and indentation method to evaluate in-vivo skin firmness and elasticity. The testing head end is particularly compact and non-gravity dependent, allowing access to small test sites such as around the eyes. The BLS780 instrument is typically used to assess anti-ageing and moisturising products, cellulite, or the quality of wound and burn healing.

Due to its versatility, the BLS780 is also our recommended alternative instrument to the Dermal Torque Meter (DTM310) which is now discontinued.

The Translucency Probe (TLS850) assesses how light interacts with the skin structure and pigmentation, absorption levels and sub-surface scattering phenomena. The TLS850 is not sensitive to any surface optical effects and measures how light is absorbed and scattered within the skin structure itself, and typically supports radiance and complexion claims.
