Thank you for sharing your photo. First, I want to say that at 23, your facial features are already well-balanced. What you're noticing appears to be a subtle concern rather than something that requires a dramatic change, which is actually a good place to start because small adjustments often create the most natural results. Looking at your profile, I do think filler could make a meaningful difference, depending on your goals. If your chin is slightly recessed or lacks projection, a conservative amount of filler can help improve the balance between your nose, lips, and chin, creating a smoother, more harmonious side profile. Regarding the chin crease, if it's present even when your face is relaxed, a small amount of filler can soften it by providing support beneath the skin. If the crease becomes more noticeable when you speak or make expressions, it may be related to the mentalis muscle, and a small amount of Botox can help relax that muscle and reduce the appearance of the crease. In many cases, the best results come from using both treatments together. One of the nice things about filler is that you'll usually notice an improvement immediately after treatment, although there can be some temporary swelling for the first few days. The final result is typically seen within about 1–2 weeks once the filler has settled. Botox, on the other hand, works more gradually. Most people begin to notice an effect within 3–5 days, with the full result developing over about 2 weeks. The key is to take a conservative approach. At your age, you don't need large amounts of filler to create balance. Thoughtful, subtle enhancement is usually enough to refine the profile while still looking completely like yourself. Overall, based on the photo you've shared, I do think filler, with or without a small amount of Botox, depending on the cause of the chin crease, could improve your profile. The goal wouldn't be to change your face, but rather to enhance your natural proportions in a way that looks refreshed and balanced.
