SEE ALSO: Taeyeon reveals behind-the-scenes of 'Letter to Myself' MV and jacket shoot

One netizen pointed out on an online community that Taeyeon may have received some sort of touch-up on the corners of her lips. There is a plastic surgery procedure commonly referred to as the "smile lift"�in which people, often females, re-align their upper and lower lips for an "upturned-lip" look.�

The netizen used the following GIFs of Taeyeon before her latest music release:

Comparing them with GIFs from her "11:11" MV:

Opinions on the matter varied, and some stated that the idol mostly likely received botox injections to accentuate a more "upturned-lip" look rather than the full on cosmetic surgery procedure.�

Comments ranged from, "Heol, if you're gonna do it, at least do it to look natural,"�"I feel like Taeyeon is very consistent with her touch-up procedures,"�"I was shocked at how different she looked in the MV," to�"Whether she gets touched-up or not, what's it to you,"�"If you have time to find these things, go study some more,"�etc.�
