Hi pammy,
After a month it almost sounds like an allergy or atypical reaction if you still have red spots? I have to keep a supply of remedies on hand at the farm, everything from poison plants to insects. Benadryl Gel is one of my favorites for all purpose. Not heavy on the anti-histamine (you should not get sleepy as if you took a Benadryl pill). But a couple years ago I found IvyDry products in the little local pharmacy back home and that stuff is miraculous for stopping poison ivy in it's tracks! (The scrub, it's like an exfoliant.) I checked their site and they do make a product for bug bites, so I'd suggest giving that a try. Hard to find closer to urban areas (at least for me) but I did find that Meijers carries some IvyDry products. (I was looking for poison ivy scrub and saw it there, but not sure about the bug product). You can check it out here. Oh, and they have a 'where to buy' tab, too.

Are you sure it's mosquito bites? Sounds to me more like chigger bites. Chigger bites can last a long time, the itching goes away but the red marks can take a few weeks to fade and disappear.

I live in Bug Alley! The sooner you treat the brown/red scars the better chance you have of them fading away. I use a product called Scarfade (on-line purchase) and have been happy with the results. I've also used Mederma (drugstore) to no effect. Can you tell I've had to deal with scars? lol

I have never found anything that worked except for immediately applying a 2% anti itch creme and it is only in the last several years that I have been doing this but it does seem to help.

I suffered terribly with the red marks in middle and high school and they almost ruined my life as I would constantly have dozens of bites on my legs and ankles and always looked diseased.
Later in life I learned to stay inside, cover up or use deet.

Let me clarify: The original red bite marks are gone. Now I just have lightish brown spots where they were--the skin is healing, but not fast enough for me anymore! They just look icky. They're not raised, like scabs, they're just slightly discolored marks.

Bumblebeez--you have it right! My arms look almost diseased to me! But the marks are just the remnants of the bug bites.

This year, I made sure to always have the Neosporin+anti-itch cream with me, and I applied it liberally to help me keep my mind off the itching.

I know exactly what you mean. It's hyperpigmentation and I think the only cure, if there is one, is time. My mother has a terrible time with bites or anything else that even light scratches her skin - she's left with terrible dark marks. They eventually fade, but for her, don't ever go completely away. I have the same problem, but to a much lesser degree. It's aggravating.

I had the marks on my ankles for over a decade. Most of them occurred (repeatedly over time)when I was under 14 and spent a lot of time outside playing.
Once I had my license...I was off to the mall.

I freak out now around mosquitoes and turn hyper if anyone leaves the door open at our house.

If you have any in not-so-obtrusive places, you might test out an OTC skin-lightening cream with 2% hydroquinone, since they're mostly inexpensive, easy to get, and fairly harmless. A dermatologist will have many more options (many of which are inexpensive topical treatments rather than only pricey stuff like laser treatments). I have many freckles and moles, and when I was cooking professionally I had many small burns on my hands and forearms from spatters, bumping into hot surfaces, etc. which would turn brown after they healed, and of course a different shade of brown from my freckles - sort of a purply brown instead of the light caramel color of my freckles and darker warm brown of the moles, which looked pretty odd. It took years for them to go away, since I thought fade creams were just for old people's liver spots ;-) and I didn't have insurance to see a dermatologist.

Interesting article, johnmari--especially because I was just perusing that woman's website the other day! (I was curious to see if she had a new book out and any rec's for facial cleansers and such--incl benzoil peroxide creams that are less concentrated than the typical store-shelf ones, cuz I really think those are too strong for my skin.)
Do you use any of her products? I remember her on so many talk shows once upon a time...

No, I don't use any of her products. I'm not a "product person" anyway, and even if I did enjoy mucking about with all that stuff mt dermatologist has me on Cetaphil cleanser and sunscreen when I'm using Extina (rx topical for seborrheic dermatitis, only thing that has ever worked to keep the skin from coming off in bleeding chunks around my nose and hairline). But even if I wasn't using the rx I don't give a rat's rump about all the 47 products the advertising industry has made us believe we need to slather all over ourselves so we don't terrify small children and animals into heart failure with the hideousness of our actual natural faces that O!!M!!G!! might normally age... or that's the beauty industry for you anyway.
