A brand identity system can realistically last 7 to 15 years if it is built on the right foundation. Chasing visual trends, whether flat, gradient or AI-drawn logos, cuts that lifespan down to 2 to 3 years. You would have to start over at a greater cost. It is a distinctive identity, repeated consistently, that helps customers remember the brand over the long term.

Every few years, a new visual wave sweeps through the design industry. A decade ago it was flat design, then vibrant gradients, then rough, clay-style 3D. After that came minimalist wordless logos, and most recently, logos generated by artificial intelligence (AI) tools in a matter of seconds. Each time, there are persuasive arguments that this is the direction of the future. And each time, a wave of businesses spends money redoing their brand identity to keep up. Three years later, they are facing the same question again.
This is not a story about which trends are right or wrong aesthetically. This is a story about money and time: what are you building, and how long will it last.
The true lifespan of an identity
A brand identity system built on the right foundation has a clear strategy, its own distinctive assets, and practical operating guidelines. This kind of identity typically lasts 7 to 15 years, because the design does not change. That core is solid enough to absorb the necessary adjustments over time without starting over.
Conversely, when an identity system is built according to trends rather than identity, its lifespan is reduced to just 2 to 3 years. Trends come and go. When they leave, your identity goes with them. And each time you redo it, it is like starting from scratch in customers' memories, as what they recognized is about to disappear.
Signature assets: what you are building or breaking
Jenni Romaniuk, a researcher at the Ehrenberg-Bass Institute, measures distinctive brand assets along two dimensions. The first is Fame, the degree to which buyers link the asset to the brand. The second is Uniqueness, the degree to which the asset is not confused with competitors. A red logo is not distinctive just because it is red. A red logo becomes distinctive when its shape, proportions and treatment are so much its own that customers know who it is from just a small corner.
The key point: distinctive assets are something you build up through repetition, not something that exists the moment you declare it. They need time and consistency to imprint on buyers' visual memory. Every time you make a major change because of a trend, you lose more than the cost of redesigning. You also lose what you had accumulated.
Distinctive identity assets only create mental availability when repeated consistently. Consistency is the mechanism of memory, not an aesthetic choice.

Why is an AI logo a sharp test?
Logo generators powered by artificial intelligence are not technically bad. They can produce good-looking images, sometimes very professional ones. The problem lies elsewhere: these tools are trained on millions of existing logos. As a result, what they produce tends to converge on the most common shapes, color combinations and treatments.
According to the Ehrenberg-Bass theory, this is precisely the opposite of what a distinctive asset needs. You cannot build Fame and Uniqueness with something readily available in the crowd. You build it with something different enough for people to recognize, and consistent enough for them to remember.
In addition, most results from today's AI logo tools do not qualify for trademark registration under Vietnamese and international intellectual property law. The reason is that originality and distinctiveness remain contested. You may be building something you cannot legally protect.
Gradient, flat, 3D: a cycle that never stops
In 2013, Apple introduced iOS 7, and the entire industry rushed towards flat design. In 2017, gradients returned, with Instagram changing its logo leading a wave. From 2020 to 2022, rough and clay 3D designs appeared everywhere. From 2024 to 2025, minimalist logos without text and pure geometric shapes are being ordered by many. Each trend has arguments about why it fits the times, users, and current devices.
But some brands are not swept up in this cycle. They keep their core assets and adjust only the application layer. These are the brands that build the strongest recognition over time. Coca-Cola did not change its red and its Spencerian typeface because gradients were in fashion. Nike did not change its swoosh because flat design rose to prominence. That is how they understand exactly what they are protecting, not conservatism.
Refreshing is not redoing: the most important boundary
There is a significant difference between maintaining a system and rebuilding from scratch. Mastercard spent 20 months researching before removing the text from its logo in 2019, as at that time, 80% of respondents recognized the symbol of two circles without needing the name. They did not change their identity. They simply simplified the application after the distinctive asset had become strong enough.
That is the right way to refresh: adjust the technical layer, such as optimizing for screens, rebalancing color for digital environments and updating how imagery is treated, while keeping the core foundation intact. This is completely different from replacing the entire identity just because this year's trend looks more appealing.
The right question is “are my distinctive assets still recognized and correctly linked to my brand?”, not “does my identity look dated?”. If so, you are maintaining. If not, you need to look at the real cause before deciding what to do.
What truly determines longevity
An identity system does not age because of time. It ages because it is not operated. Printed brand guidelines get left in a drawer, new staff don't know they exist, print partners use the wrong color files, social media uses whatever fonts come to hand, and the website and catalogue don't match. After two to three years of that disorder, the identity really does look dated. The reason is not outdated design, but that no one carries it out consistently.
This is why a good identity system must include an operational layer, not just a visual layer. Guidelines must be practical enough for non-designers to use. Design tokens (a set of color values and typography defined consistently across all platforms) need to be integrated into the digital process from the start. And someone must be responsible for keeping that system alive.
A brand is not lost because a competitor overtakes it. In many cases, it is lost because it is eroded from within by inconsistency built up over many years. Chasing visual trends every few years only speeds up that process.
