# Polynucleotides with Mesogun with Léobel

> Polynucleotide treatment is an advanced regenerative skin therapy that stimulates the skin's natural repair processes, improving texture, elasticity, hydration, and overall skin quality. Administered using our mesogun for greater precision, enhanced product distribution, and minimal discomfort, the treatment delivers consistent results while maximising comfort. Ideal for improving skin laxity, fine lines, and tired or damaged skin, polynucleotides promote healthier, firmer, and more radiant skin over time. For optimal results, a course of 3 treatments is recommended, spaced approximately 3–4 weeks apart. Price: £300.
