Although actinic keratosis produces rough or scaled skin nodules because of sun damage, seborrheic keratoses are similar to a mole. They are typically tan or brown in color and spherical or elongated in shape. They could routinely emerge as if they have been fused to the skin similar to a sticky label, while actinic keratosis might have a sensation of a rough area of skin. To confirm the kind of keratosis you are experiencing, you should speak to a Prestige Cosmetic Dermatology specialist who can give you a definitive conclusion.
