Skin signal
Hydration
Moisture depth, plumpness, and skin comfort
Hydration is the foundation — when skin is dehydrated, every other signal looks worse. MIRU distinguishes between surface dryness (flaking, tightness) and deeper dehydration (fine dehydration lines, dullness) so your routine targets the right layer.
What dermatologists assess
Surface flaking and rough texture (transepidermal water loss)
Dehydration lines vs true wrinkles (disappear when skin is wet)
Skin plumpness and turgor
Oil-water balance (oily yet dehydrated is common)
