Understanding PIH

You have this patch of dark mark
that occurred after a botched IPL clinic procedure. So you go to your
dermatologist and she tells you it’s some kind of PIH. You ask her, “What’s a
The doctor’s reply makes you even more worried. “Oh, it’s short for post-inflammatory hyperpigmentation.” What you thought to be a minor burn mark sounds
like a very serious concern.

So what really is PIH? When skin is
injured, or inflamed, the healing process can turbo boost the production of
more pigmentation. The injured spots become darker. Now, you see the
connection. PIH refers to darkening of affected skin after the inflammation has
gone away.

Common examples are dark marks from improper
acne pricking, and astringent burns made worse by sun exposure. Aside from the
face, what other body parts are prone to PIH? Underarms! Many have dark
underarms due to antiperspirant use. Also, elbows and knees. They become dark
with constant skin trauma from friction.

Anyone can get PIH. However, if you
have darker skin, you will have higher tendency to suffer from PIH than those
with light skin. Those dark spots will eventually fade by themselves. This may
take up to two years, though.

Your dermatologist can explain to
you various treatment options to hasten the departure of dark marks. Topical
treatment with skin lightening creams can be the most cost-effective
option.  Exfoliants like DERMAX Retinol C
serum help produce faster lightening. 

Topical cortisone cream should be applied
only with medical supervision. Prolonged use can worsen PIH.

Diamond peel and chemical peels
containing either glycolic acid or TCA are clinic procedures that will strip
away the topmost skin layer to reveal fresher, lighter skin.

Old discolorations and scars can be
successfully treated with more radical procedures like collagenesis
(dermaroller) and fractional laser therapy.

With time and the proper treatment,
those dark spots will eventually fade away. One thing is a must, though. You
have to avoid unnecessary sun exposure. Be sure to have daily sun protection
that fits your skin condition, from the DERMAX UV line of sunscreens.
