Skin Needling and Fractional RF are similar in the sense they both cause a controlled wound which then triggers a healing response where new collagen and elastin fibres are produced. Skin Needling is an organic way of stimulating Collagen and Elastin production whereas Fractional RF uses a combination of dermal stamping and Radio Frequency. Radio Frequency uses deep thermal effects which result in contraction of the collagen fibres. This will give a tightening effect after the treatment.
