Skin signal
Early signs of expression and sun ageing
Fine lines appear where skin creases most — around the eyes, forehead, smile lines. They are a function of collagen turnover, hydration depth, and cumulative UV exposure. MIRU measures their visibility change between scans.
Depth and visibility of periorbital lines (crow's feet)
Forehead and glabellar (frown) line prominence
Nasolabial fold depth relative to age baseline
Skin elasticity and bounce-back when gently pressed
Retinol / Retinal
Gold standard for collagen stimulation and cell turnover.
0.3-1% retinol; retinal is faster-acting with less irritation
Peptides (Matrixyl, Argireline)
Signal skin to produce more collagen without the irritation of retinoids.
Copper peptides for repair, Matrixyl 3000 for prevention
Hyaluronic Acid
Plumps fine lines temporarily by drawing water into the skin.
Multi-weight HA penetrates better than single-weight
Vitamin C
Cofactor in collagen synthesis, protects existing collagen from UV damage.
Morning use under sunscreen for best protection
This reflects standard dermatological guidance — educational, not a personal assessment. For persistent or changing concerns, a dermatologist is best placed to help.
