I suddenly feel like the cushion doesn't suit me. Could it be because my skin tone has changed?

I've been using this cushion for months and it's been fine, but lately it looks particularly thick.
I'm not sure if it's a problem with the puff or my skin condition.
Even using the same amount, it feels like it breaks down faster than before.
I'm confused whether it's because the seasons have changed or if my skin has changed.
I'm debating whether changing my cushion is the answer or if I need to adjust my skincare routine.
My skin doesn't look the same as it used to, so it bothers me all day long.
If the existing product feels unsuitable, is it better to replace it immediately?
Or should I check my skin condition first?
I was using this product just fine, so I'm really frustrated wondering why it's suddenly acting up.
