Skin signal
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.
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)
Hyaluronic Acid
Holds up to 1000x its weight in water, plumps from within.
Apply to damp skin, seal with an occlusive
Glycerin
The most effective humectant by clinical evidence — steady, reliable hydration.
Present in most well-formulated moisturisers
Squalane
Mimics skin's natural sebum, locks moisture without clogging.
Olive-derived or sugarcane-derived are identical in function
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. For persistent or changing concerns, a dermatologist is best placed to help.
