My Friends Keep Asking If I’ve Had Filler, but I Promise It’s Just This New Lip Liner

Earlier this week the office manager told me my makeup looked great, and a few hours later, a fellow beauty editor looked me dead in the eye and told me, "That lip liner is really working for you." Yesterday, when I did my weekly check in on my neglected WhatsApp inbox, I realised that I had missed a group-chat conversation between my friends about whether or not I'd had lip filler. So, after all of the compliments and debate, I'd like to take this moment to let something be known: no, I have not had lip filler, I've just been wearing the new Merit Signature Lip Liner.

When I found out a couple of months ago that Merit Beauty was launching a lip liner, I had mixed feelings. I adore everything that the brand touches thanks to its lazy-girl-approved formulas and low-fuss ethos. But a Merit lip liner? I wasn't sure. You see, I consider myself Merit's number one fan—I find great joy in aesthetically appealing products, I adore comfortable formulas that look natural on the face and, crucially, I prioritise products that are seriously quick and easy to apply. To be frank, lip liners are fiddly by nature, require some level of precision and add an unwanted step into my makeup routine.

But after wearing it for a full week, I can officially confirm that Merit Signature Lip Liner is the most mind-blowing lip product I've ever used. It is not a lip liner in its truest form, but it is also more than just a lip contour (like the also recently launched Rhode Peptide Lip Shape). It shapes, contours and creates the illusion of fuller lips, sure, but it does it all with an unrivalled sense of ease and a very convincing finish. Here's what to know...

The Product

Let's start with the packaging and the product itself. At face value, Merit Signature Lip Liner looks just like any good lip liner does. It is a wind-up pencil, so you don't have to mess around with any sharpening—perfect for those who, like me, never have to sharpener to hand and instead just throw blunt pencils in the drawer to be forgotten about. And as is always the case with Merit products, it looks beautifully chic.

The one visible difference between this and other lip liners out there, however, is the rounded nib. Rather than a super-pointed, sharp, pencil-like nib, Signature Lip Liner has a slightly thicker (but not too much so) tip that is rounded for smooth, easy, non-precise application. The beauty of this product is that it is not designed for precision, meaning it's almost unbelievably easy to use.

The Finish

A few days ago, Merit shared on Instagram the original brief that the team penned ahead of creating Signature Lip Sheer Lip Liner. It stated that the product should be:

  • "Sheer, buildable and comfortable enough to wear every day"
  • "A soft gel formula that doesn't tug or crumble"
  • "Hydrating so that lips feel soft and moisturized"
  • "Versatile so you can use it as a liner or to fill in lips all over"

The brief also stated that the formula should not be "dry, stiff or crumbly" and that they never set out for it to be "highly pigmented or long-wearing".

The result? A formula that is creamy and glossy in finish and that deposits enough pigment to make a difference, but not enough that it would ever cause application issues. Merit has clearly stated that if you use traditional lip liners often this formula will likely not be for you—which, frankly, speaks to me as a lip-liner hater. This is a lip liner for makeup minimalists.

The Application

If I haven't made it clear enough already, I'm totally inept when it comes to makeup application—my hands are clumsy, and I don't have a single artistic bone in my body. Because I'm so scared of lip liner, last week, I organised a visit to one of the most talented experts around, makeup artist Zoë Taylor, so that she could school me on how to use the new Merit Signature Lip Sheer Lip liner.

She told me that the key is to not get too caught up in the concept of overlining. Instead, just to follow the natural outline of my lip and concentrate the product more towards the outer corners of my lips, filling from the outside in. She assured me the glossy, gel-like formula will do the rest. The one tip she did give me, however, was to stop trying to accentuate my cupid's bow with liner. "Just draw straight across and round your cupid's bow off," Taylor told me. "This creates the illusion of more fullness."

Armed with all of the information I needed, I went home and tried it for myself immediately. Unlike every other lip liner I've ever used, it glides on with gloss-like ease. And I say gloss here because the finish isn't particularly creamy—it has a water-like level of hydration that imparts a dewy, diffused sort of pigment. This quality makes it sheer on first swipe but beautifully buildable.

The Results

Once I've traced the outline of my lips, rounded off my cupid's bow and filled the corners of my lips in (leaving the middle sections bare), I have been applying the Merit Shade Slick over the top—one of my favourite tinted lip oils ever created. Merit has launched four new shades to accompany the new liners, dubbed "The Sheens". Each one of these shades has a slight pearlescent shimmer to further boost the illusion of fullness. My favourite pairings are Signature Lip Liner in Bespoke with Shade Slick Sheen in Twin Set (below) and Signature Lip Liner in Beverly Hills with Shade Slick Sheen in Biarritz (above).

And as for the lasting power? I appreciate Merit's transparency with this. The brand never promised that Signature Lip Liner would last ages—it's a hydrating formula with a sheer, gloss-like finish, so it's never going to deliver the staying power of a matte lip liner. Having said that, I'm pleased to say it lasts a lot longer than I thought it would. After applying first thing in the morning, I find myself topping up my Shade Slick perhaps once every hour or two (depending on how much I've been talking, eating and drinking) and needing to reapply my Signature Lip Liner perhaps every three or four hours. But I want to make it clear here that this liner does not dry out or flake like others—it simply gradually fades away without any concern of cracks or smudges.

One thing to note here is that due to the super-hydrating, gel-like nature, I find myself using more product than usual. This isn't a problem considering I just twist the bottom of the pencil up while applying, but it's worth noting that you can expect to get through it quicker than you would a traditional lip liner.

All in all, I'm a woman obsessed. I truly never thought that lip liner would be a product for me. I can't apply it, and I've never been convinced the results could be groundbreaking enough for me to stress over it. However, with Merit Signature Lip Liner, I'm willing to admit that I was wrong—I just needed to find the right product.
