Senile Freckle (Lentigo Senilis)
The most common sunspot. Laser treatment is the first choice for this
type, though topical bleachers are needed to prevent recurrence. The spot
that has come out for years might need multiple sessions. The followings
are the treatments for this spot.
This laser treatment will show scabs that last for 1 week. A week later the scab will peel off with the lasered spot.
Intense Pulsed Light(IPL)
IPL, with its numerous brand names, is a kind of light that is
free of harmful kinds such as ultra violet. This device can treat freckles
but not as strong as laser. The downtime is just few redness that will
not last long. It is applicable to the whole area of the face skin for
the treatment of not only spots but also redness from vascular problems.
BBL(Broad Band Light) and FotoRF Aurora are the brands available in our
clinic. BBL has more power than FotoRF.

Tretinoin + Hydroquinone Treatment
Tretinoin is a weak acid that peels off the keratin(old skin) at
the skin surface stimulating the turn over of the skin to the newer layer
2 times faster than the regular process. In this event, hydroquinone, a
strong whitening substance, can function easier and faster to eliminate
the discoloration. This treatment is good for spots that is not treatable
with lasers or for those who are not comfortable of using laser devices.
This is also a good remedy to prevent recurrence or side effects after
Highly absorbable vitamin C & E lotion and oral prescription,
topical and oral transamenic acid, ionic and sonic massages,
and chemical peeling are also available as whitening regimen.
Inborn freckles are usually hard to erase but can be lighten up with
whitening treatment. IPL, Q-switched laser, and other whitening remedies
can be used in the same way with senile freckles. (See above for details.)
Melasma seen on skin of Caucasian descent might be treatable by lasers
and IPL. But on Asian, African-American, or Latin-American skin, treatment
with devices might worsen the color. So with these skin types, tretinoin
and hydroquinone regimen is the main whitening course, combined with other
topical and oral substances. Melasma's specific cause is not clarified
yet, but it is believed to be associated with female hormone activity.
As long as the hormones are active, melasma will never go away. So the
mentioned treatment is just to lighten up discoloration.

Skin tag is a benign fibroma(fibrous tumor) that is said to appear on
aged skin. Usually seen on the neck, eyelids, armpit, etc. Laser abrasion
with erbium or CO2 is effective. (See erbium laser picture above)
