Freckles by definition are varying shades of brown. Your skin spots are red. Most red sopts(often called Cherry Angiomas) are benign and remain unchanged over years. I would advise you to take a picture or two for your records and watch( 1-2 of these lesions over a year or longer to see if they change in size or color. I do not think you have any cause for worry. Tell me in one year what U observe
