In aesthetic medicine, a filler is a substance injected into the dermis or subcutaneous tissue to correct skin imperfections, touch up facial blemishes such as wrinkles or scars, and restore lost volume. Literally, "filler" means "something that fills": these substances are injected into the dermis to fill and smooth out facial wrinkles and other signs of ageing. Aimed at skin rejuvenation, filler injections are an innovative and effective alternative to, or valid support for, plastic surgery. Filler injections are indicated in the following circumstances:
- Fill and smooth wrinkles around the eyes (so-called crow's feet) and mouth
- Increase/reshape the volume of thin lips
- Correct nasolabial folds
- Shape the form and volume of cheekbones, chin and forehead
- Fill folds and hollows typical of ageing
- Eliminate scars left by acne or surgery
For deep wrinkles, injections of hyaluronic acid-based fillers are used, with a medium-term effect. To reduce and eliminate expression lines, botulinum toxin is used instead.
