Skin Rejuvenation with IPL
IPLs use filtered non-coherent light to selectively destroy pigment cells, blood-filled capillaries and hair roots in a process called selective photothermolysis. It works by causing thermal damage to target chromophores (pigments) by using light of appropriate wavelength in pulses that exceeds the chromophores’ thermal relaxation time. Surrounding skin left untouched by limiting the pulse width below the thermal relaxation time for skin.
IPL technology has come a long way nowadays as we can achieve clear skin in just one, or at most two, treatments. The idea is to produce a very uniform power throughout the pulse width.
Telangiectasias are widely open (dilated) blood vessels in the outer layer of the skin. About 30 % of fare skin population suffer from the telangiectasias.
The most common factor in occurrence of facial telangiectasia is weakness of the vessel walls due to chronic sun exposure. Genetic predisposition, liver disease, surgical trauma, radiation therapy, chronic steroid use, deep chemical peeling of the face may also play a role.
Telangiectasias are red, blue, or purple linear marks measuring less than 1–3 mm in width and several millimeters to centimeters in length, and they can disappear temporarily if you press on them with your finger.
IPL’s selective photothermolysis is best options to treat abnormal vessels. The vessel temperature increases to 60 – 70°C causing the abnormal vessels destruction. Adjacent tissue far less absorbs light of “vascular” laser and don’t injuring. Complete or almost complete clearance achieved in 90% of patients.
Telangiectasias on cheeks are usually easy to treat. Telangiectasias of nasal alae are more complicated for treatment and required particular caution. Some patients with telangiectasias of nasal alae may be resistant to the treatment (about 4%).
Over exposure to the sun causes significant damage to the skin which creates a variety of issues such as age spots, freckles, pigmentation, wrinkles and a decrease in collagen.
Sun damage causes the melanocytes (pigment carrying cells) in the skin to be stimulated thereby producing more pigments to protect the skin. Over time, the melanocytes become abnormally concentrated in an area producing these uneven skin tones. The results are freckles, age spots, uneven skin tones, dilated capillaries and wrinkles.
IPL for Pigmentation
IPL treatments are superior at reducing hyper pigmentations by pushing the offending pigment out of the cells. This treated area will appear as a mild scabbing however, will slough off within one- two weeks. Scrubbing is not permitted in this healing time. The result achieved is even skin tone, reduced capillaries and fresh rejuvenated skin.
The longer the pigment has been present and the severity of the pigment plays a major role in the expected results. It is harder to remove a pigment that is very deep and has been present for over a long time;
Significant and satisfactory reduction can usually be achieved in most patients expect a slight darkening of freckles, age spots, liver spots etc, and slight ecchymosis “dirty skin discoloration” over burst fine capillaries immediately after each treatment. These would then fade after 1-2 weeks to reveal a much clearer complexion. During the usual follow-up visit at 7-10 days, many patients are stunned at how much clearer their skin have become. Follow-up all your IPL treatments after 1-2 week with microdermabrasion to remove any “crusts” left behind.
PIGMENTARY CONDITIONS IN ASIAN SKIN – Melasma
Asian women around 40 years of age will have several kinds of pigmentation on the face. IPL effectively lightens age-spots and sun-induced pigment spots but not Melasma. Melasma is hard to remove as they are deep. Against a clearer background, the Melasma stands out more prominently after IPL.
