I am a woman in my early 40s, and I'm worried because it's my first time getting Botox or fillers.

I am a woman in my early 40s. Recently, the hollowing of my cheeks has become noticeably worse, and my nasolabial folds have deepened. I am very concerned because my overall appearance looks tired and dull. My forehead also looks sunken compared to before, and I have even been told that I look older than my age. People around me recommend getting Botox or fillers, saying they make me look much younger and improve the condition naturally, but I am very worried since this is my first time getting the procedure. I have heard that Botox is effective for wrinkle reduction and fillers help with hollowing of the cheeks or forehead, but I am wondering if the satisfaction rate is actually high. I would also like to know if it is common to receive both Botox and fillers together, and which method is more suitable for someone receiving the procedure for the first time. Above all, I have heard so many stories about the side effects of fillers and Botox that it is difficult for me to make a decision easily. I would appreciate your advice regarding the experiences of those who have actually undergone the procedure, essential points to check when choosing a clinic, and tips for achieving a natural look.
