Guide to matching household beauty equipment with skincare products: Choose the right ingredients to enhance efficacy and avoid skin damage

The working principles and operational key points of three types of household beauty devices: radio frequency, ultrasonic, and iontophoresis/electroporation.

Today’s article centers around the principle of ingredients, clarifying what to use, what to avoid, and how to arrange for different skin types.

1. Radiofrequency beauty instrument

① works by heating the dermis layer with radiofrequency energy, promoting collagen contraction and neogenesis. Simultaneously, the thermal effect temporarily enhances the permeability of the stratum corneum (by altering lipid arrangement), facilitating the absorption of water-soluble small molecules. Therefore, when using the instrument, it is recommended to choose a moisturizing and low-irritating essence or gel, avoiding heavy, closed oils or strong irritating medications.
② Adaptation components
• Hyaluronic Acid (Sodium Hyaluronate) – Deep Moisturizing • Panthenol (Vitamin B5) – Repairing Barrier • β-Glucan – Soothing, Enhancing Immunity • Glutathione – Antioxidant, Brightening
③ Advanced option: Lightweight O/W/O multiple emulsion face cream (special case)
Most face creams are unsuitable as radiofrequency media due to their high oil content and thick texture, which can cause viscosity and hinder heat dissipation. However, some face creams with a triple structure of O/W/O (oil-water-oil) may become an option, rather than the first choice, when applied very thinly, at low settings, and with skilled technique.

2. Ultrasonic beauty instrument

① Matching principle
Ultrasonic waves rely on mechanical vibrations to “push” effective components into the skin, and must rely on water-soluble media for coupling. Oil and grease can severely attenuate ultrasonic wave transmission and form an air gap between the probe and the skin, leading to inefficiency or even localized burns.
② Adaptation component
• Water-soluble L-ascorbic acid
• Hyaluronic acid (HA)
• Panthenol

3. Iontophoresis and Electrolysis Instrument

① Matching principle
The iontophoresis device utilizes the principle of micro-current repulsion of like charges to facilitate the penetration of water-soluble, charged components with a molecular weight less than 500Da into the skin. For extraction, it relies on charge attraction to adsorb positively charged dirt (such as metal ions and sebum oxides) on the surface of pores.
The export medium must be a mild aqueous solution containing electrolytes; pure water is ineffective.
② Importing adaptable components
• L-ascorbic acid (vitamin C) – water-soluble and negatively charged
• Niacinamide – weakly charged, oil control and brightening
• Tranexamic acid – water-soluble, inhibits melanin
Export adaptation
Mild toner containing sodium chloride or minerals (such as saline solution, mineral spray).
③ Taboo
Fully oil-based skincare products (oil does not conduct electricity) and high-concentration acids (irritating and damaging to electrical conduction).
