Although both Venus Viva and Secret RF are advanced skin treatments, their methods of action differ slightly: Venus Viva tightens, reduces scars, and improves skin texture using NanoFractional Radio Frequency (RF). It performs miracles for overall skin rejuvenation. RF energy and microneedling are combined in Secret RF. As it targets the skin's deeper layers, it is useful for treating more serious skin issues like fine wrinkles and deeper scars. In conclusion, Venus Viva performs miracles for superficial rejuvenation, whereas Secret RF operates deeper to address more serious skin conditions. Your decision is based on your individual goals and skin issues.
