HarmonyCa Lido is an FDA-approved dermal filler. One of the main benefits of HarmonyCa Lido is that it stimulates collagen production, which is vital for healthy and youthful-looking skin. Collagen is a protein that gives our skin its elasticity and firmness. As we age, our collagen production decreases, causing our skin to sag and wrinkle. By stimulating collagen production, HarmonyCa Lido helps to restore the skin’s elasticity, reducing wrinkles and fine lines.
