Skin-Nomad's Take — At a Glance

• Hydrating lip oil with a mirror-like glossy shine
• Squalane and plant oils with a light coconut scent
• Wear alone or over a tinted balm

Most of us give up on gloss for how it feels by hour two, not for how it looks in the first ten minutes. The Trew Cosmetic GlowLip Hydrating Lip Oil takes its mirror shine from squalane and plant oils, so the glassiness and the conditioning turn out to be the same thing rather than a trade. Trew Cosmetic is a French brand working on lips and very little else.

Key Features

• Squalane is the reason it wears like nothing: Squalane is close to the oils skin makes for itself, so it settles into the lip surface instead of sitting in a layer on top of it. The shine stays put; the weight never arrives.
• Light bounces off the oil in a sheet, which is where the mirror comes from: A clear oil film reflects evenly across the whole lip rather than in specks, and that is what reads as glassy instead of glittery. On bare lips the effect is wet; over colour it looks lacquered.
• Behind the shine are olive and castor oils: Their fatty acids soften a rough lip surface and slow the water leaving it while you wear the oil. A day in it leaves lips smoother than they started, so the shine and the lip care are one step rather than two.
• Expect a light coconut scent and a single-sweep application: The texture is a thin oil that glides on without dragging and needs one pass rather than layers. The scent is a light coconut rather than a sweet or heavy one.

Ideal For

• Skin types: All skin types, including dry lips that want the shine step to condition rather than only coat.
• Pigmentation and finish: No colour at all, so the finish is pure mirror shine that reads glassy on bare lips and lacquered over a tinted balm.
• Best used by: Gloss wearers who like the look and have quietly stopped wearing it because of the sticky, hair-catching feel.

FAQ

Q: How is a lip oil different from a regular lip gloss?
A: Conventional gloss gets its shine from wax, and wax is what makes it tacky and heavy on the lip. A lip oil produces the same shine through the way light bounces off the oil, so the finish is glassy while the feel stays light, and the oils condition the lip through the wear rather than only coating it.

Q: Do oils actually hydrate lips, or do they just coat them?
A: Strictly speaking, oils do not add water to the lip. They soften the surface and slow the rate at which water escapes from it, which is exactly right for lips that look dull and feel rough. Lips that are genuinely dehydrated do better with a water-based hydrator such as a hyaluronic acid balm underneath, and the oil layered over the top to hold it there.

Q: Can I wear it over lipstick or a tinted balm?
A: Yes, and it goes on last when you do. Over a tinted balm it turns a soft finish glassy and deepens the colour a shade, and on bare lips it works perfectly well as clear shine on its own.

There is a quiet irony in the glossiest thing in your bag also being the kindest to your lips.
