Some products sell out because of their formula, others because of their price, and others simply because they take us right back to a school backpack. The collaboration between KIKO Milano and STABILO belongs to that last group: lip tints inspired by the iconic fluorescent highlighters that, according to statements from KIKO Milano Iberia reported by Vogue España, sold out on the brand’s online store in under five hours.

But beyond the headline, the more interesting question is a different one: why can a stationery item we used to review our notes turn into such an instant beauty must-have? Let’s break it down calmly.

What we know about the collaboration

The limited edition turns the recognizable design of STABILO highlighters into lip tints. According to what has been published, the brand said it was working to meet demand, although no restock date has been confirmed. So if you missed out on yours, the wisest move is to follow KIKO Milano’s official channels and avoid resale purchases at inflated prices, where it is also harder to verify the product’s authenticity.

It’s worth separating facts from assumptions: the five-hour figure comes from the brand itself, and there is no public information on units produced or total sales. What we can do is look at the factors that usually explain this kind of phenomenon.

Why nostalgia sells

So-called nostalgia marketing consists of bringing back elements of the past, such as objects, aesthetics or sounds, to evoke positive emotions tied to a specific stage of our lives. In this case, the highlighter evokes classes, exams, overflowing pencil cases and colors impossible to ignore.

What makes this proposal special is that it doesn’t revive an old beauty product, but instead moves an everyday object into a new context. That unexpected twist works for several reasons:

Scarcity matters too

A limited edition adds a different emotional ingredient: urgency. When we know a product will only be available for a short time, the purchase decision speeds up. It’s a common mechanism in the industry and not exclusive to beauty, but combined with nostalgia it becomes especially powerful.

Collecting rather than need

Many people who buy this type of launch don’t do it because they need a new lip product, but because they want a small object with meaning. The packaging, the design and the story it tells weigh as much as the shade. It’s an emotional purchase, and there’s nothing wrong with admitting that.

Social media: the engine of the conversation

A product with such a recognizable design is almost an invitation to take a photo. Comments like “I had one just like it at school” spark spontaneous conversation, and that conversation works as advertising nobody paid for directly. Social media amplifies the effect: what starts as a personal anecdote becomes a shared trend.

Moreover, nostalgia has an advantage in the digital environment: it’s easy to communicate. One image and a short phrase are enough for someone to understand the concept and want to join the conversation.

What this says about makeup in 2026

This collaboration fits into a broader trend: beauty is moving closer to play, collecting and pop culture. It’s increasingly common for makeup to be seen not just as a tool, but as a form of expression and fun. Vibrant colors, packaging with personality and unexpected collaborations coexist with a search for products that tell a story.

It’s also a sign that many consumers are looking for meaningful experiences, not just functional items. A brand that can move us in five seconds has a big advantage over one that merely lists features.

How to shop wisely (and without regrets)

If nostalgia sends you straight to the buy button, these ideas can help you decide more calmly:

The deeper lesson

The success of this collaboration can’t be explained by a single variable. Design, surprise, scarcity, social media conversation and, above all, a very human emotion all play a part: the desire to reconnect with who we used to be. Buying a memory in the form of a lip tint isn’t frivolous; it’s a light and fun way to celebrate our own story.

It remains to be seen whether KIKO Milano will announce a restock or new editions. In the meantime, the case leaves a clear idea: in beauty, sometimes the newest thing is to look back.
