Material: ABS + stainless steel Product size: 16 * 14.5cm Fashion beauty therapy: This beauty device features micro-needle technology, a popular method for skin rejuvenation. It uses tiny needles on a roller wheel to stimulate collagen and elastin production, helping improve skin texture. Active ingredients can penetrate more effectively, supporting skin renewal and addressing concerns like wrinkles, scars, and uneven skin tone. Micro-needle specifications: This product features a standard 0.5 mm / 0.75 mm micro-needle roller with an elastic silicone design. Made from durable materials, it is designed for facial and body skincare, offering flexibility and resilience for effective and safe use. Multi-function and effective: Suitable for both men and women, this micro-roller can be used with your preferred serums or creams to help support skin health and hair growth. Helps reduce the appearance of fine lines, enlarged pores, and signs of aging. Can assist in improving eye wrinkles, tightening facial skin, and enhancing overall skin texture. Promote metabolic growth: The micro-needling process creates micro-channels in the skin, which may stimulate blood flow to the treated area, trigger the body's natural repair process, and promote collagen production—key factors in skin renewal and health. Frequency of use: Micro-needling does not need to be performed daily. For most users, use up to twice a week is recommended. If skin sensitivity occurs, reduce frequency to once a month. Always clean and disinfect the device before and after use. Not intended for individuals with sensitive or allergy-prone skin.
