When I look in the mirror right after washing my face, the surface looks rough and dusty, completely devoid of radiance. When I apply foundation, not only is dead skin cell flaking obvious, but it also clumps up messily into every pore, to the point where I feel it would be better to just go out with a bare face. I heard that hyaluronic acid injections work by simultaneously firming the skin's density and texture, rather than just providing a temporary dewy glow. Is that correct? I heard that because it is a nano-particle dispersed formula, it spreads smoothly deep into the skin without clumping. Could you please advise which method is more effective for improving skin texture: using an injector device or having the doctor administer it meticulously by hand, strand by strand? Thank you in advance for your comments.
