Undereye bags — A.K.A. swelling and puffiness under the eyes — are a telltale sign of aging. (The converse, sunkenness under the eyes, also tends to occur more often with age.)
The cause of both undereye bags and sunkenness is similar: As you age, the tissues around your eyes weaken. Normal fat and muscle that support the skin around the eyes, keeping it taut and firm, begin to diminish. For some people, this results in sunkenness (a “hollowing out”) under the eyes. For others, it results it these undereye bags (swelling and puffiness).
Recently, tattoo artists became makeup artists when they started to use tattoos to place pigment under the skin permanently. The idea is that the weight of the pigment under the dermis will mimic some of the natural fat and muscle, and the color itself will of course eliminate the need for concealer. Another added benefit is that the needles work like microneedling, increasing blood flow to the area, and hence drainage and collagen production. However, this effect is temporary, lasting only for a few weeks.
The issues here, unfortunately, are multifold and longer-lasting. This is not a great idea. According to tattoo artist Holly Starcevich, “The initial results look great, but the reality is that the treatment does not age well, and the pigment is almost impossible to remove. Skin tone pigments have a high concentration of white, which is a titanium molecule. Titanium molecules are huge, and heavy. Underneath the skin, they sink, swell and discolor with repeated sun exposure. It ends up looking like yellow cottage cheese under the skin.”
Instead, for dark circles and undereye bags, follow my advice here (for dark circles) and here (for undereye bags).
