Meaning of "绽开来" in 这句话让她脸上的皱纹菊花般绽开来? 她的话音刚落,一直在旁边默默无语的老公说道:“我们就是后一种。”这句话让她脸上的皱纹菊花般绽开来。"


Just after she spoke, her husband who'd been staying in silence beside her said, "We're the latter kind." This remark made the wrinkles on her face...?

Mmm, I really couldn't understand this. Does it mean open/smoothen? If that's the case, why's is said to be "like chrysanthemum?"
绽, 绽放, means bloom/blossom.

皱纹菊花般绽开来 means the wrinkles bloom like chrysanthemum, which is used to describe smile here.



To be honest, using 绽放 instead sounds more natural to me.
