Skin signal
Smoothness, bumps, and cell turnover clarity
Texture is what you feel when you run your fingers across your skin — bumps, rough patches, closed comedones, and uneven grain. MIRU photographs texture in detail and tracks whether exfoliation and cell turnover are actually smoothing the surface.
Presence of closed comedones (skin-coloured bumps)
Keratosis pilaris or milia
Rough vs smooth zones mapped across the face
Cell turnover rate — how quickly dead skin sheds
AHA (Glycolic / Lactic Acid)
Dissolves the bonds between dead cells, revealing smoother skin underneath.
Glycolic (strongest), lactic (gentler + hydrating), mandelic (sensitive skin)
Retinol
Accelerates cell turnover from below, pushing new smooth cells to the surface.
Start low, go slow — 0.25% for beginners
PHA (Gluconolactone)
Gentle surface exfoliation with humectant properties — works without irritation.
Ideal for sensitive skin that cannot tolerate AHA/BHA
Urea (5-10%)
Keratolytic at higher concentrations — softens and sheds rough, flaky patches.
Excellent for body texture (KP) and very dry facial skin
This reflects standard dermatological guidance — educational, not a personal assessment. For persistent or changing concerns, a dermatologist is best placed to help.
