. I picked out the darkest one and tried rubbing it to see if it would disappear, but the next morning I noticed it got darker. Now I have a single dark freckle right smack dab in the middle of my forehead
Hello,
It looks like a small hyperpigmented patch or a freckle. Use liberal amounts of sunscreen, avoid the sun, and wear protective clothing. The newest treatment is an alpha hydroxy acid gel or beta hydroxy acid gel. Retin-A cream, alpha hydroxyacid peels, and liquid nitrogen therapy are other options. Please discuss these treatment options with a dermatologist.
