Local allergic responses to many tattoo pigments have been reported, and allergic reactions to tattoo pigment after Q-switched laser treatment are also possible. Rarely, when yellow cadmium sulfide is used to "brighten" the red or yellow portion of a tattoo, a photoallergic reaction may occur. The reaction is also common with red ink, which may contain cinnabar (mercuric sulphide). Erythema, pruritus, and even inflamed nodules, verrucose papules, or granulomas may present. The reaction will be confined to the site of the red/yellow ink. Treatment consists of strict sunlight avoidance, sunscreen, interlesional steroid injections, or in some cases, surgical removal. Unlike the destructive modalities described, Q-switched lasers mobilize the ink and may generate a systemic allergic response. Oral antihistamines and anti-inflammatory steroids have been used to treat allergic reactions to tattoo ink.
Experimental observations of the effects of short-pulsed lasers on tattoos were first reported in the late 1960s by Leon Goldman and others. In 1979 an argon laser was used for tattoo removal in 28 patients, with limited success. In 1978 a carbon dioxide laser was also used, but because it targeted water, a chromophore present in all cells, this type of laser generally caused scarring after treatments.
Half-sleeves or quarter-sleeves are tattoos that cover only part of an arm, usually above the elbow, but can also be found below the elbow. A sleeve implies complete tattoo coverage of a particular area, so a half sleeve is a tattoo that covers the entire upper or lower arm. A "quarter sleeve" usually covers the area of skin from the shoulder midway to the elbow.
Do not wrap your tattoo again unless the artist says so. It’s highly important to keep the tattoo clean after the protection has been removed. Keep in mind that your new tattoo is similar to an open injury. Plenty of tattoo artists recommend hand-washing the tattoo lightly but thoroughly with your clean fingers, using an unscented and anti-bacterial soap. Let it air dry or pat it gently with a dry and clean paper towel. Everything you use or touch should be clean. It’s also common for a new tattoo to be inflamed, red, or sensitive.
Card symbols have long been popular symbols to get inked. The ace of spades is usually the most popular one to get but not far behind are the Queens. The queen of clubs symbolises a strong willed and positive person. Tattoos in between the fingers usually need to get redone every few years as they do fade due to the amount of rubbing that occurs there.
