When choosing a beauty device, the decision between radio frequency (RF) and non-RF options depends on your own skin condition and anti-aging needs. RF beauty devices are more suitable for improving skin sagging and wrinkles, while non-RF ones focus on instant firming or basic skincare. There is no absolute superiority or inferiority between the two.
In terms of working principles, RF technology heats the dermis with high-frequency electric current, which can stimulate collagen regeneration. Long-term use improves skin elasticity, making it ideal for people over 25 with early anti-aging needs. Non-RF devices (such as microcurrent and LED light therapy) mainly promote blood circulation or repair the skin with light waves, delivering obvious instant lifting effects that last for a short time. They are more suitable for daily maintenance of young skin or sensitive skin.
Beauty Tip: RF devices are better for those pursuing skeletal facial firmness, whereas non-RF devices prioritize the delicacy of the skin surface. If your skin is thin or in a sensitive state (e.g., acne breakouts, sunburn), it is recommended to choose non-RF devices first to avoid aggravating irritation from high temperatures.
Notes for using any beauty device:
- Usage frequency: RF devices are recommended for 2-3 times a week, while non-RF ones can be used daily.
- Matching medium: RF devices must be used with conductive gel to prevent skin burns.
- Expectation management: The effect of at-home devices is weaker than that of medical aesthetic treatments, and long-term consistency is required.
If you are unsure about your skin condition, it is advisable to first conduct a skin test to learn about your collagen density and skin elasticity, then select a targeted device. A beauty device is just an auxiliary tool for daily skincare maintenance; maintaining a healthy work-rest routine and sun protection are the fundamentals of anti-aging.
