Structural remodeling at the dermal root.
Traditional microneedling stimulates epidermal repair through physical mechanical punctures. Radiofrequency (RF) microneedling elevates this by delivering controlled biphasic heat directly through insulated micro-needles into the reticular dermis (up to 4.0mm deep).
By bypassing the outer skin layer and heating the deep tissue between 55°C and 65°C, it triggers immediate collagen contraction followed by long-term collagen and elastin synthesis without epidermal burns or hyperpigmentation risk.
