I think there are several reasons why kiku's face value changes so obviously.
First of all, kiku should have been fine-tuned. Kiku's face and nose are much more delicate than when he first debuted. His face changed from round to oval, and his nose became tighter, making kiku more exquisite.
Secondly, it has a lot to do with kiku's body management. When kiku first came out, he was still a little baby fat, and his facial features were not very strong. Later, kiku paid more and more attention to body management, and his body became slimmer and whiter, which made kiku look more beautiful and lovely.
In addition, it also has a lot to do with kiku's aesthetic changes. When kiku first made his debut, he was not very sensitive to fashion and wore old clothes. However, in recent years, kiku's dressing taste has improved obviously, and he has found a dressing style that suits him, so he has become more fashionable and naturally more beautiful.
More importantly, kiku's makeup. Kiku's makeup lighting on the Internet is very old-fashioned, but now it's kiku's? Semi-permanent? Make-up suits her very well, pure and charming, which shows kiku's temperament well.
Finally, the most important thing is the improvement of temperament. Kiku has been in the entertainment circle for so many years and has his own unique temperament. The change of temperament has the greatest influence on a person. People with good temperament will make people look more beautiful, energetic and eye-catching.
Although kiku has been controversial, as an audience, as long as kiku's works are excellent, we should pay attention to her works, so don't care too much about how kiku's beauty comes from and stay away from the private lives of stars!
