Cathy Doll X Maeng Smooth Blur Lip Liner

Most lip liners are built to draw a hard line, and then you spend two minutes trying to soften it. This one skips the argument. The tip is rounded to 3.8 mm — wider than a standard liner point — so the line lands slightly soft on contact, and one fingertip pass turns it into shadow instead of outline.

WHY IT GLIDES
The base is 20% methyl trimethicone, a featherweight volatile silicone that carries the color, with isononyl isononanoate at 10% and diisostearyl malate at 6.2% doing the emollient work. That combination is why the tip moves over dry patches without dragging or skipping.

WHY IT STAYS PUT
The same light silicone evaporates within minutes of application. What remains is the part that matters: a film of trimethylsiloxysilicate (7%) and polysilicone-11 (5.94%) holding the pigment against the lip. No wear test exists for this product, so you won't find an hour count here. What we can tell you is that this is the film system long-wear formulas are built on.

THE BLUR IS IN THE POWDERS
Silica at 4%, backed by silica dimethyl silylate and a touch of mica, scatters light across the color instead of letting it sit flat. That optical softness is the difference between a lip that looks shaded and a lip that looks traced.

DARK EDGES, HANDLED
Every shade carries real titanium dioxide coverage — between 4% and 6.6% depending on the color — which is what lets it neutralize darker lip edges and work as a full-lip base under lipstick or gloss. Shade 03 is named Pink Primer for exactly this job.

✓ 3.8 mm rounded tip lays the line down soft, so the blurred edge takes one fingertip pass instead of a cleanup session
✓ Glides on a 20% featherweight silicone base, with 10% isononyl isononanoate and 6.2% diisostearyl malate handling dry patches
✓ Sets as the light silicone flashes off, leaving a 13% film-former pair (trimethylsiloxysilicate + polysilicone-11) holding pigment in place
✓ 4–6.6% titanium dioxide per shade — enough coverage to neutralize dark lip edges and prime the whole lip under lipstick
✓ Blur comes from the formula, not just technique: 4% silica plus silica dimethyl silylate scatter light across the color
✓ 12 shades across pinks, corals, and browns, with the deep terracottas and chocolates that suit medium and deep skin tones
✓ Fragrance-free, paraben-free, anhydrous — no water, no drying alcohols
✓ Twist-up pencil, no sharpener needed, and the rounded tip keeps its shape

1. Twist up about 2 mm of core. It's a soft-set core by design; more than that and it can snap sideways.
2. Outline from one corner toward the other, then fill in the center for a defined, polished lip.
3. For the blurred version, press inward with a fingertip or brush until the outline reads as shadow rather than line.
4. Using it as a base: fill the whole lip, then layer lipstick or gloss on top for dimension.
5. Give it a few minutes to set — the film forms as the lightweight silicone evaporates. Blot once before it does if you want a thinner stain of color.
6. Twist fully down before capping.

Caution: Stop using and seek medical treatment if any signs of abnormality appear. Keep out of reach of children.
