Dear Pepperjack, et al.,
Before seeking a solution to a problem it’s best to know what the problem is in the first place. It’s funny that clients sometimes experience something on their skin and then start slathering just about anything on it to make it “go away.” Don’t do that.
I’ve been harping-on about PIH for a couple years now, so I won’t bore everybody who has had to SUFFER reading my tortuous book-like posts. (Resident windbag here.)
Stopping hyperpigmentation is like trying to stop a moving freight train with a fly swatter. It’s going to stop … but in its own sweet time.
Just remember a couple things. First, your PIH is not from an (electrolysis) error; it’s from the nature of your skin itself (I think you already know that).
Furthermore, the PIH is not something that happens once. No, the pigment production (new “bundles”) is going to continue as long as the skin is healing (and thus stimulating your melanocytes).
An “immediate” solution will, perhaps, take out some older higher-up-in-the-epidermis pigment; but new pigment will be manufactured (eventually fewer and fewer as the skin heals).
If you find a “product” you may have to use is for a long time; a nice mild one is recommended. No need to use hydrocortisone or “skin peeling” and don’t waste your money on “micro-dermabrasion," (unless the operator is a babe!).
Jossie and Dee have given good suggestions. Be careful, don’t make matters worse. It’s going to go away … chill out? (If you only have this on your neck, I’d rather see you use a little … hold on to your butt … makeup!)
Well, there it is … another “book!” Sorry people! Damned windbag!
