It could really glow up in one’s face.

The summer travel season means people are scrambling to renew their passports with many embellishing their photos so they look more flattering. However, experts have warned against these photo “glow-ups” on the grounds that they could make it more difficult for flyers to navigate immigration checkpoints.

“If you overly-enhance your look when taking your photo, you can actually slow down the process of verification checks at the airport,” warned Gemma Brown, the Head of Product at the UK travel site Travel Republic.

Google searches for “how to take a passport photo” shot up by 213% in the past month as travelers clamored to replace their passports in time for a final summer jaunt, according to the site.

As a service to worried vacationers, Australian reality star Amelia Marni even made a viral TikTok tutorial on how to glow themselves up with makeup on picture day so their passport snap looks less like a mugshot. The video currently boasts over 3.5 million views.

Unfortunately, while these photo makeovers may seem glamorous, they can also make customs an even bigger hassle than normal.

In one clip with nearly 7 million views, TikTokker Beth Gould recalled how passport machines couldn’t match her glammed-up photo with her natural look, forcing her to go through ID checks with airport staffers.

“Basically I don’t look like my passport photo,” the traveler lamented.

“It’s important to remember that the reason for a passport photo is to provide a clear and accurate visual identification of you,” explained travel expert Gemma Brown.

She added, “Most people do feel embarrassed of their ID images, however, they are a security measure to help prevent fraud, keep borders safe and ensure easy recognition of the traveler’s identity.”

Therefore, if the passport photo doesn’t mirror the actual traveler, they might have to go through additional security vetting procedures.

The US Department Of State stipulates that passport pics must be color photos taken on a white or off-white background that use a clear image of the subject’s face.

They must also be shot by someone else (no selfies) and not be enhanced with computer software, filters or artificial intelligence.

The subject is also forbidden from wearing eyeglasses, hats or head coverings, except for religious or medical purposes.

Travelers don’t need to apply for a new passport over minor appearance changes such as growing a beard, hair dye or the natural aging process.

However, they do need to do so if they underwent any major transformations, including significant facial surgery or trauma, the adding or removing of large facial tattoos or piercings and gender transitions.
