Instensyl (Cassava Tensor): The Complete Guide
Instensyl® is a plant tensor that gives skin an immediate smoothing, supported feel. This guide explains what it is.
What is Instensyl®?
Instensyl® is a branded tensor based on hydrolysed cassava (Manihot esculenta) tuber. Tensors form a fine, flexible film on the skin as they dry, gently drawing the surface taut for an instant, temporary smoothing and lifting effect — the “instant” part of a product’s result, alongside the actives that work over time.
What does it do?
- Immediate smoothing — a visible, temporary tightening as it sets.
- A more supported look — softens the appearance of fine lines on application.
Where we use it
Instensyl® contributes the immediate smoothing feel in Blue Copper 5 PRIME Sleep Tight Mask. See the Ingredient Glossary for the full formula story. Individual results vary.
