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)
Top actives for hydration
A 0.1% periocular study reported improved hydration and elasticity over 60 days.
This receipt does not establish deeper-layer penetration
Human studies of 20% glycerin creams found improved human skin hydration; the whole formula and measured endpoint matter.
The reviewed studies tested complete creams, not every glycerin product
Used as an emollient in moisturisers; whole-formula performance varies.
Olive and sugarcane labels describe source, not stronger evidence
Ceramides
Rebuild the moisture barrier so water stays in instead of evaporating.
Essential if skin feels tight after cleansing
This reflects standard dermatological guidance. Educational, not a personal assessment.
