I think this is like a small form of acne but on my arms. It's not really noticable, like I can still wear a normal t-shirt during the summer but Id still want to clear it up. My aunt gave me a cream called "Concha Nacar" (in Spanish; oyster shell), which they sell at the Flea Market (not sure if thats the only place they sell it, its just where my mom and I went to buy more). There's 3 of them; a day cream, night cream and a bleach cream. The day cream you can also use as a primer/base for makeup, and the bleach is the one that gets rid of the marks left after picking your skin and spots/blemishes. So if you're thinking of using this one, use all 3 of them. I still kinda have it but it seems to be working. My aunt's sister actually had the same thing I have and it worked for her, and hopefully me and anybody else
Oh another thing, the package is in both Spanish and English. When you open it, it also comes with a piece of paper that says which cream does what but only in Spanish.
