I'm worried about loss of elasticity, so I'd like to know more about the features of Density High!

Now that I've entered my mid-30s, I can definitely see my skin losing firmness day by day, and the side of my cheeks sagging slightly right before my eyes. Since my facial silhouette looks uneven, it makes me look older and feels a bit down, so I'm looking into lifting devices that promise to really tighten and firm my skin. I've heard that Density-High is the trend these days among radiofrequency lifting treatments because it significantly reduces pain, making the procedure comfortable! What are the distinct features of Density-High that clearly differentiate it from other existing Thermage or radiofrequency lasers? I'm really looking forward to hearing firsthand advice from beauty experts on whether it's true that Density-High fills your body with collagen painlessly, even with just anesthetic cream applied!
