At age 31, nasolabial folds (the lines running from the nose to the corners of the mouth) are completely normal, especially with expressive facial movements. However, if their appearance at rest is bothersome, several long-lasting treatment options can help soften them. 1. Dermal Fillers (Hyaluronic Acid or Biostimulatory Fillers) Effect: Immediate improvement by adding volume beneath the folds. Longevity: Hyaluronic acid fillers (like Juvederm or Restylane) typically last 9–18 months. Biostimulatory fillers like Sculptra or Radiesse stimulate collagen and can last up to 2 years. Best For: Moderate volume loss and patients seeking non-surgical correction. 2. Fat Transfer (Autologous Fat Grafting) Effect: Uses your own fat to fill in volume loss around the folds. Longevity: Considered semi-permanent; results may last years, though fat survival can vary. Best For: Those seeking a more natural, long-term option and willing to undergo a minor surgical procedure. 3. Thread Lifts Effect: Minimally invasive threads are inserted to lift and reposition sagging skin, improving the fold depth. Longevity: Results last 12–18 months. Best For: Early skin laxity and mild to moderate folds. 4. Energy-Based Skin Tightening (RF or Ultrasound) Effect: Stimulates collagen to tighten the skin around the mid-face and folds. Longevity: Results develop gradually and can last 1–2 years with maintenance. Best For: Mild laxity or as an adjunct to volume-based treatments. Conclusion: Yes, nasolabial folds are normal at 31, especially if you're expressive or starting to lose some mid-face volume. For long-term softening, dermal fillers, fat grafting, and collagen-stimulating treatments are effective and commonly used. Combination approaches often yield the best results over time.
