Another possibility is that there could be other factors contributing to your dull complexion, such as not drinking enough water, lack of sleep, or stress. These factors can have a direct impact on your skin's appearance.

　　If you're concerned about your complexion, it might be a good idea to consult a dermatologist or a nutritionist. They can provide personalized advice and help you figure out the best course of action. It's important to remember that there is no one-size-fits-all solution, so what works for others might not work for you.

　　Lastly, don't be too hard on yourself! It's normal to try different things in order to improve our health. If celery juice didn't have the desired effect on your complexion, it's not the end of the world. There are plenty of other natural remedies and skincare routines that you can explore. Just keep in mind that everyone's skin is unique and it may take some trial and error to find what works best for you.
