I interpret this as being about taking advantage of life/seizing the moment because nothing in life is guaranteed. It might also be about being grateful for what you have (although this seems less likely for a beauty product marketing campaign).

I would use a more "active" phrase that emphasises the positive action we can take when we realise that nothing is certain: seizing the day/seizing the moment/living for the moment/carpe diem/etc.

With the context of the full sentence, I would agree that the speaker is talking about living in the moment. Given that it's part of a beauty campaign, a phrase that captures the importance of life seemed fitting. "Everything isn't obvious" is too direct of a translation to fit in the context. I realized that after looking at the other responses.
