The four main causes
Hollow dark circles come from a loss of volume under the eye: the tear trough deepens and casts a shadow. Pigmented dark circles are an accumulation of melanin, common on olive or dark skin and in people who rub their eyes or have eczema or allergies. Vascular dark circles, bluish or purplish, come from very thin skin that shows the vessels. Finally, eye bags can make everything look worse. The causes often add up.
How to tell the difference at home
In front of a mirror, gently stretch the skin under the eye: if the colour stays, it is more likely pigmentation; if it disappears, it is more likely vascular. Light yourself from above, then from the front: if the shadow vanishes with front light, it is a hollow. This test helps you find your bearings but does not replace an examination, which alone can separate overlapping causes.
Hollow dark circles: hyaluronic acid filler
When the problem is a hollow, it is filled with filler: a hyaluronic acid gel injected in a very small amount into the tear trough. It is a delicate area, so it is reserved for a trained doctor: the skin is thin, an excess shows, and there is a vascular risk. The product is placed precisely, the clinic’s ultrasound can help depending on the case, and hyaluronic acid can still be dissolved if there is a problem. The filler generally lasts 12 to 18 months under the eyes, with variations.
Pigmented dark circles: laser, skincare and sun protection
A brown dark circle is not filled, it is treated through the skin: strict sun protection, prescribed depigmenting care, and sometimes a low-energy pigment laser, with caution on olive skin so as not to trigger more pigmentation. If something keeps the dark circle going (eczema, allergy, rubbing), it has to be treated first, otherwise it comes back.
PRP and nanofat, for skin quality
PRP, prepared from your own blood, and nanofat, a finely prepared fat, improve the thickness and quality of the skin under the eye. They are mainly used for thin, tired skin, or for mixed dark circles, sometimes combined with filler. They work gradually, over several sessions for PRP.
Eye bags: how far does aesthetic medicine go?
A mild bag linked to swelling or slight fat can improve with some treatments, but an established bag often calls for eyelid surgery. Dr Zahid does not claim it: she tells you clearly when the right procedure is elsewhere and refers you to a surgeon, without giving you a treatment you do not need.
Preparing, and what to do afterwards
Mention blood-thinning treatments. After filler, avoid intense heat, intense exercise and massage of the area for 24 to 48 hours; slight swelling or bruising is possible for a few days. After a laser, protect the skin from the sun. Sharp pain, white or purplish skin or a change in vision require an immediate call.
