Trends are ephemeral; your photographs are forever. While heavy contouring or neon-bright liners might be "in" this season, they can often mask your natural beauty rather than enhance it.
The danger of following trends blindly is that they are often designed for a specific "ideal" face shape that doesn't account for individual diversity. For example, the trend of extreme "baking" under the eyes can highlight fine lines in dry skin types, and heavy matte foundations can look flat under modern LED event lighting. Balancing inspiration with suitability is key. If you love a trend, adapt it—don't just copy it.
