Description

Technical Field

[0001] This invention generally relates to the field of medical aesthetic devices. Specifically, this invention relates to an electronic device and its control method. Background Technology

[0002] In everyday life, there are many situations where it is necessary to apply liquid medications or skincare products to the skin. The most common methods include applying with bare hands, wiping with cotton swabs, or applying with gauze, but these methods are usually inconvenient, unhygienic, and difficult to measure precisely.

[0003] In recent years, numerous liquid medication application tools have emerged, incorporating features such as droppers and rollerballs to create shapes resembling combs, rollerball bottles, and droppers. These tools effectively address the inconvenience of applying liquid medications directly to the skin and have gained widespread use in scenarios requiring long-term, regular medication application. For example, in treating hair loss, where long-term application of liquid hair growth medication is necessary, the medication can be easily applied to the designated areas on the scalp by rolling it into a rollerball bottle. However, these products often lack precise dosage, and due to repeated use, cross-contamination and hygiene issues remain a concern.

[0004] In addition, areas of skin where liquid medications and skincare products are typically applied have a complete skin structure. However, due to the barrier function of the stratum corneum, the penetration of most drugs, biological therapeutic agents, and skincare products into the skin is significantly reduced, greatly increasing the difficulty for these products to achieve therapeutic and skincare effects. Furthermore, larger molecular weight drugs or skincare ingredients are difficult to penetrate the skin, hindering transdermal application. To address these issues, many corresponding products have emerged, among which microneedle rollers are very popular due to their good penetration-enhancing effects, ease of use, and cost-effectiveness. However, microneedle rollers usually need to be used alone; that is, the skin surface must be treated with the microneedle roller first, followed by the application of medication, a very complicated process. While some products integrate drug dispensing functions, they suffer from difficulties in quantitative dispensing, unstable dispensing, and the inability to achieve cleanliness and hygiene.
