A flat forehead is one that extends straight from the hairline to the eyebrow without curvature when observed from the side. Generally, a curved forehead creates a better profile line and often gives off a more youthful look because it mimics those of babies and children. The latest trend in Korea is to have a round and nicely curved forehead.
A flat forehead is a normal variant of the different shapes of forehead for different individuals, just like everybody is born with a different face shape. It can also be caused by congenital disorders, where a person is born with skull and facial bone abnormality.
Filler injection is fast and only takes about 20 - 30 minutes while a fat graft may take 1 hour as it involves extracting fat from the client’s own body and injecting it back to the forehead under local anaesthesia.
Hyaluronic acid filler can last from 1.5 to 2 years, whereas a fat graft can last from 2 to 3 years.
Most of the time there is no downtime with fillers and clients can resume their work and activities on the same day of their filler injections. There might be mild swelling, a few transient needle marks and occasionally bruises from the treatment. Clients who undergo fat graft however, will have a longer downtime as the swelling and bruising are more significant. Recovery time may take a few days.
Injection related risks and side effects such as pain, redness, bruises and itchiness are most commonly seen and they usually resolve spontaneously within a few days. The risk of bruising can be reduced by avoiding blood thinners or supplements like vitamin E, gingko, ginseng, ibuprofen and aspirin.
Rare complications associated with filler injections include infections, skin discoloration, lumpiness and vascular compromise. The risks for fat graft include allergic reaction to local anaesthesia, temporary sensory loss, infection and bad bruising.
Client is advised to avoid putting pressure or massaging on the treated area and to avoid strenuous exercise and alcohol for 24 hours to avoid extra bruising. He or she should sleep with the face up and apply an ice pack wrapped in a thin cloth or a cold gel pack to reduce swelling and bruising.
