Thank you for your detailed question and the photo. Based on what you’ve shared and shown — visible volume loss and fine creasing around the midface when smiling, this appears to be dynamic volume depletion and tissue laxity, which is common in thin, athletic individuals in their 30s, especially those with low body fat and strong facial muscle activity. Why Botox Isn’t Enough Botox works by relaxing muscles to reduce wrinkles caused by movement. However, the smile lines and creasing you’re showing are more related to volume loss and skin elasticity, not muscle overactivity. So Botox alone won’t be effective in this case — especially when you're already treating forehead and crow’s feet. Sculptra vs. Filler vs. SkinPen Here’s a breakdown of the best options: 1. Sculptra (Poly-L-Lactic Acid) Ideal for thin, athletic faces who want gradual, natural volume restoration without the “puffy” look. Stimulates collagen production over time, improving skin texture and volume subtly. Best for those who are patient with results (it takes 1–3 months to fully show) and want something that ages gracefully. Works well in temples, midface/cheeks, and nasolabial areas. 2. Hyaluronic Acid Fillers (e.g., Volbella, Belotero) If used, you’ll want a very soft, low-density filler in precise amounts. Can provide immediate correction, but carries a higher risk of looking unnatural if not placed properly, especially in thin skin. Requires maintenance every 6–12 months. 3. SkinPen (Microneedling) Great for fine lines, texture, and early creasing, but won’t replace lost volume. Works best in conjunction with collagen-stimulating treatments like Sculptra. Minimal downtime and effective for skin tone and smoothness, not lifting. Recommendations Given your: Thin facial structure Avoidance of a puffy look Desire for natural results Commitment to skin care and prevention → Sculptra would be the most appropriate treatment to rebuild subtle collagen and support skin structure without altering your natural expression or fullness. You can also complement Sculptra with SkinPen treatments for enhanced skin texture and firmness, particularly around dynamic areas like the smile lines.
