Hyperpigmentation is characterized by a darkening of an area of skin caused by the overproduction of pigment or melanin. It is relatively common and harmless, but for cosmetic reasons, it is a nuisance to those who have it. There are various causes of hyperpigmentation, including overexposure to the sun; sun damage; heredity; picking at the skin; hormonal changes; certain medications such as antibiotics, hormone treatments and antiseizure drugs; and inflammation and skin injuries such as acne vulgaris.
At Quang Minh Clinic, we use Erbium:YAG laser to target the surface layer of the affected skin area, vaporizing water and the skin’s surface without affecting deeper layers. A new surface layer will then grow back – a layer that is colored-even, soft and younger looking. The heat generated during the process also shortens the collagen fibers in the skin, which restores some of its elasticity.
You will be consulted about technique and treatment process.
Apply skin anesthesia cream and wait for around 30 minutes.
Scan Erbium:YAG laser onto the hyperpigmented area. This step will last to 30 minutes.
Apply antiseptic and instruction for self-care at home.
Depending on whether the hyperpigmented is shallow or deep, 1-2 sessions will be indicated with 6-8 weeks apart between each one.
Again, it depends on depth of the scar. If patient maintain correctly indicated number of session, effectiveness can reach 90%.
The laser can cause an unpleasant stinging. There may be pain, bruising and swelling over the treated area for a while after each session. During treatment period, patient skin is extremely vulnerable to sunshine, heat and water. Hence, minimized exposure to these factors is requested to prevent infection or darkened skin in the aftermath.
As previously mentioned, there are 2 main causes of hyperpigmentation that are, external causes (sunshine, chemical, cosmetics etc.) and internal ones (hormonal disorder, aging etc.). A combination between removal of hyperpigmentation area and treatment of its causes is necessary to prevent recurrence.
Depending on the area, cost for each session might range from VND 1.000.000 to VND 2.000.000.
