The information provided by you is limited. It is very important to know your age, site of red spot at forehead (i.e. whether in mid forehead, sides, or near hairline etc.)and the size &Shape of the spot(e.g. circular, pinhead, pencil tip with regular margin or irregular margins). Also it very important to know is whether it is same size since you noticed or it is increasing in size (Gradually increasing or rapidly).
However as it is not itchy and does not have any other symtoms and as you mentioned that redness
only goes away if you apply pressure on it most probably it is a case of "Cherry Angioma". it is benign leision comprising of a clump of dilated blood vessels that develope under the topmost layer of skin.it is generally cherry red in colour and blanches under finger pressure.
Treatment :-This is harmless skin condition and does not require removal per se. However in case you are bothered by it due to cosmetic point of view it can be treated by Laser
or by Cryotherapy
.These are nonsurgical methods and generally do not leave scar marks. Surgery even done by utmost care by cosmetic surgeon will leave residual faint scar mark. Advantage however of surgery however is that the red spot leison removed can be subjected to laboratory analysis(Biopsy
) and definate diagnosis can be achieved.
You can attach the photo of the leison so that I can analyse you problem completely and can further enlighten you.
