The Lip Duo with its color swatches
What Makes The Lip Duo Different?
It is two products in one pen. One end is a precise lip liner that redraws the contour. The other is a creamy, full-coverage lipstick. Both ends carry a Korean peptide serum with palmitoyl tripeptide-1, hyaluronic acid and ceramide NP that plumps and hydrates while you wear it.
How Do I Use It?
Pull off the liner cap, twist up the tip and draw your lip contour. Do the same on the other end and fill in with the lipstick. One pen, both ends, thirty seconds. No separate liner, no separate balm.
Will It Bleed Into My Lip Lines?
The built-in liner creates a barrier that locks color inside the lip line. The formula was designed specifically for mature skin: it stays put without feathering into perioral wrinkles, even hours later.
How Long Does It Last?
Up to 12 hours. The liner locks the edge and the color sets into a soft satin film that resists water, coffee and meals, without drying your lips. After a very oily meal, one quick swipe brings it back.
How Does It Come Off?
A gentle makeup remover or micellar water takes it off cleanly. No scrubbing, no staining. Your lips feel soft, not stripped.

35,000+ women are proud of their lips again

Your Lips Change After Menopause.

After your eyes, your lips are what people look at first. After menopause, they thin fast.

Collagen drops

Collagen drops

Estrogen tells skin cells to make collagen. Without it, up to 30% is lost in 5 years, and lips, with no fat pad underneath, deflate first.

Less hyaluronic acid

Less hyaluronic acid

Lower estrogen also means less hyaluronic acid, the molecule that holds water. Lips lose volume and lines deepen.

The border fades

The border fades

The lip edge is built on collagen and elastin. As they thin, it flattens and lines form around it, so color wicks into them.

Slower renewal

Slower renewal

Cell turnover slows from about 28 days to 40 or more, so dry cells build up and lips stay rough and cracked.

The problem isn’t your lips. It’s that most lipsticks were designed for a 25 year old woman.

Classic Lipstick Sits On Top. The Lip Duo Works Underneath.

One end redraws the shape your lips lost. The other fills it with color wrapped in a peptide formula that conditions while you wear it.

Redraws The Border

Redraws The Border

The fine liner end catches every curve, so thin lips get a fuller, crisp outline.

Fills Without Feathering

Fills Without Feathering

Creamy color stays inside the line you drew, not in the lines around it.

Conditions While It Colors

Conditions While It Colors

Peptides and hyaluronic acid plump and hydrate with every wear.

From Day One To Week Eight

The color defines your lips today. The peptide formula works on the lips underneath, every time you wear it. Bare lips, no makeup, same woman.

Thin Lips, Defined In Seconds

Lips have lost volume and their border has faded. From the first coat, the liner redraws the contour and the color fills it in, so they look fuller right away.

Individual results vary.
