Pairing the right serum with your beauty device can double the results – but the wrong pairing can cause irritation or render the device useless.

By technology:

Iontophoresis (ion导入): Use water-soluble actives like niacinamide, vitamin C derivatives, hyaluronic acid. Avoid oil-based serums.

Microcurrent (EMS): Must use a water-based, oil-free conductive medium. Best: aloe vera gel, hyaluronic acid serum. Avoid: oils, silicones, fragrances.

RF (Radiofrequency): Use dedicated gel (insulates and conducts energy). Follow with: peptide or hyaluronic acid serum. Avoid: high-concentration acids (AHA/BHA) or pure vitamin C immediately after.

LED therapy: Apply on clean, dry face. After LED, any serum is fine, but always use sunscreen AM. Pair blue light with niacinamide for oil control.

Golden routine: Cleanse → LED → RF/EMS (with dedicated gel) → rinse gel → repair serum → moisturize. Bookmark this chart and never waste your beauty device’s potential.
