Permanent Eyeliner
at TEO

At first glance, permanent eyeliner may appear to be nothing more than "a fine line drawn above the eye" — but in reality it is a micro-pigment design that determines your face's symmetry, the visual proportion of your eye shape, and the character of your gaze. At TEO Beauty Centre, a 30-minute facial analysis session is always carried out before any eyeliner procedure. The angle of your brows, whether your eye is oval, almond-shaped, or slanted, the lift height of the upper eyelid, and the micron-level asymmetry between the two eyes — all of these inform our design decisions. Our aim is never to draw a generic line; it is to create a definition that feels like a natural extension of your face, as though you have always had it.

There are three principles that underpin a good eyeliner design: the right direction, the right thickness, and the right ending point. The direction should not run parallel to the eye's natural curve but should correspond to the angle of your brow. The thickness should be fine enough not to restrict the eyelid's range of movement, yet defined enough to give you the feeling of being "put together" the moment you wake up. The ending point should fall on the imaginary line drawn from the outer corner of your eye to the outer end of your brow — a millimetre too high and the face becomes severe; a millimetre too low and you look tired. We have been measuring and applying these three principles for years; the result is a line that our guests describe not merely as "beautiful" but as "perfectly suited to me and completely natural."

Permanent eyeliner is planned across two sessions. In the first session, pigment is placed into the upper layer of the skin; the second session takes place 30–45 days later to fill in any areas where the pigment has not fully settled. During the time between the two sessions, we observe how the colour behaves on your skin and make any adjustments together. This two-session approach means you can defer the question "should it be a little darker?" — because any adjustment you wish to make can be carried out at the second session.

Despite its name, permanent eyeliner does not remain fixed forever — and that is a good thing. Changing trends, the subtle shifts in your facial proportions over the years, and variations in your skin tone at different life stages mean that the same line may not suit you to the same degree a decade later. Depending on skin type, age, level of sun exposure, and the quality of the pigment used, the eyeliner applied at TEO fades gradually over a period of 1 to 3 years. This fading process is not sudden but very gentle; one day you will look in the mirror and feel that "it is time for a refresh."

Pigment selection is critical for preventing colour distortion. Some lower-quality pigments on the market shift to blue, green, or red tones over time because the carbon particles they contain break down at different rates. For this reason, TEO Beauty Centre works exclusively with pigments that carry international dermatological approval and are based on pure carbon or iron oxide. These pigments fade over time from dark grey to light grey — they never turn blue or green. With an annual refresh session, your eyeliner can be kept looking as fresh as the first day; many of our guests have maintained the same line for years with a brief 30-minute touch-up once a year.
