Deep lines / wrinkles

Deep lines, often called wrinkles, are caused by repeated facial
expressions. They are commonly found on the forehead, between
the eyebrows, or as “crows feet” around the eyes. When the
muscles underneath the skin are activated in a facial expression,
the skin above “bunches up”. Over time, this constant creasing of
the skin’s support layers (the dermis) results in permanent
wrinkles.
 
Despite the claims of many companies, topical products cannot
erase deep lines. The most effective treatment is wrinkle relaxing
injections, such as Botox, which can temporarily deactivate the
muscles responsible for causing the wrinkles. 

Dermal fillers can also help with deep lines in the forehead  and around the mouth.
 
Sunscreen and collagen-boosting vitamins, such as retinaldehyde
and vitamin C can minimise the severity of wrinkles by helping to
ensure that the dermal structure remains intact. 
 
MYTH BUSTER
It’s a commonly held belief that moisturisers assist with deep
lines. While a moisturiser may slightly plump the skin around a
wrinkle, it cannot erase or prevent these lines for two reasons:
1.They cannot penetrate to the dermis where the wrinkles form
2.The problem is not caused by dryness. The dermis, where
wrinkles form, is always moist.
