However when the melanin is deposited unevenly in the skin, they can appear as unsightly and ugly hyperpigmented skin lesions like:
These skin hyperpigmentations can be aggravated by
Skin pigmentation can involve
Melasma is an acquired skin pigmentation disorder. It is characterized by greyish brown patchy discoloration on both cheeks, nose bridge, forehead, chin and above the lips.
It typically affects women and is aggravated by sun exposure, hormonal replacement therapy and birth control pills.
Types of Melasma
There are 3 different types of melasma
Pigmentation treatment options for Melasma
Dr Lim will carefully assess your skin pigmentation and devise a treatment protocol that is individualized to your needs.
Melasma pigmentation treatment can include the following
Freckles are flat, brownish spots usually present at the cheeks, nose or sun exposed areas like shoulders and back.
Freckles are easily removed by Q switched Nd Yad lasers.
After treatment, the scabs will usually drop off in 3-5 days, leaving a lighter complexion.
Most patients usually require 1-3 laser sessions to clear the freckles.
Age spots (Solar lentigos) are benign skin conditions that usually occur after the age of 40 years old.
They are due to the proliferation of melanocytes and accumulation of melanin pigments within the skin cells (keratinocytes) as a result of sun exposure.
Age spots (Solar lentigos) appear as flat, well circumscribed patches. They can be round, oval or irregular. Color varies from skin color, tan, dark brown or black.
Laser treatment can usually remove the age spots (solar lentigos ) in 2-3 sessions.
Seborrheic keratosis are a very common non-cancerous skin growth in older adults more than 40 years of age. They usually appear as a brown, black or light tan growth on the face, cheeks, shoulders or back.
Seborrheic keratosis have a waxy, scaly, slightly elevated appearance. Seborrheic keratosis can be removed easily using CO2 laser or Nd Yag Q switched laser.
Acne, chickenpox, insect bites and eczema can cause post inflammatory hyperpigmentation in the skin.
The hyperpigmentation is due to the deposition of melanin within the keratinocytes (skin cells) and/or dermis after skin damage. Inflammation in the epidermis stimulate melanocytes to increase melanin synthesis and to transfer the melanin to the surrounding keratinocytes (epidermal melanosis).
If the basal layer is injured (e.g lichen planus), melanin pigment is released and subsequently trapped by macrophages in the papillary dermis (dermal melanosis).
Acne is a very common cause of post inflammatory hyperpigmentation. But thankfully post inflammatory hyperpigmentation caused by acne can be removed/lightened by Q switched Nd Yag laser.
It usually takes 3-5 session to clear the post inflammatory hyperpigmentation.
He will assess your skin condition and devise an individualised treatment program consisting of laser, creams, chemical peels or transdermal delivery of whitening and anti aging solutions to suit your needs.
Q switched Nd Yag laser produces a light of specific wavelength. This laser light, when directed into the skin, is absorbed by pigmented skin lesions. The light will shatter the melanin pigment into micro particles. These micro particles are naturally carried away by the blood stream and eventually removed from the body. The skin pigmentation is then lightened after a few sessions.
Q switched Nd Yag laser can
Most patients tolerate the laser treatment very well.
It feels like the snapping of rubber band on the skin.
The number of treatment sessions will depend on
Generally, the deeper lesions like melasma require 5-10 treatments whilst superficial lesions like freckles and age spots usually require 1-3 treatments.
It is important to maintain a good skin care and sunblock regime to prevent or slow down the recurrence of the pigmented lesions.
Maintenance laser sessions every 3-4 months will also improve and prevent pigment from forming.
