The dermis is the layer where collagen and elastin—which support the skin’s firmness and elasticity—are found. Intense Ultra targets this dermis to support collagen production. In this article, we’ll introduce its features and benefits.
Benefit 1 | Addresses a Variety of Skin Concerns

Intense Ultra is a beauty device that uses high-density ultrasound to deliver energy to the dermis. By delivering energy to the dermis, it supports collagen production, which can help improve skin firmness and elasticity. Additionally,By using three different frequencies—10 MHz, 3 MHz, and 1 MHz—we can address a variety of skin concerns.It is also characterized by
| Frequency | Expected Benefits |
| 10 MHz | Brightens Skin Tone · Soothes the Skin |
| 3 MHz | Improved Firmness and Elasticity |
| 1 MHz | Maintaining Sebum Balance and Massaging Sebaceous Glands |
In addition, Intensive Ultra offers the following three benefits:
| effect | function | What to Expect |
| Micro-massage Effect | Vibrational Energy from Ultrasound | ・Supports blood and lymphatic circulation and reduces swelling
・Promotes collagen production to improve firmness and elasticity |
| Thermal Effects | Ultrasonic energy generates friction within the tissue, producing heat | ・Boosts metabolism to soothe redness and skin irritation |
| Biochemical Effects | Temporarily increases sebum permeability through cavitation caused by ultrasonic vibrations | ・Since even large-molecule drugs can penetrate more easily (※down to the stratum corneum), this expands the range of available treatment options. |
Benefit 2 | Suitable for Sensitive Skin
Intense Ultra is designed to minimize pain and heat during treatment, making it suitable for people with a variety of skin types.Since it can also help repair tissue and reduce inflammation, it's perfect for people with sensitive skin.. Furthermore, because it helps maintain skin health—through moisturizing, soothing, and enhancing the absorption of active ingredients—it is sometimes used to soothe skin that has become sensitive due to recurring skin problems or rosacea.
Benefit 3 | Works Well in Combination with Other Treatments

There are also treatments that, when combined with Intense Ultra, can help reduce downtime. In South Korea, a leader in the beauty industry, it is common to combine treatments that involve downtime with Intense Ultra.
Skin-nourishing injections are another treatment that pairs well with Intense Ultra. After receiving skin-nourishing injections, your skin may temporarily become uneven.When used in combination with Intensive Ultra, it is expected to help the skin become more receptive to the product.Can be done.
Benefit 4 | Consistent use can also improve skin texture

Intensive Ultra minimizes skin irritation and features treatments designed with skin sensitivity in mind, making it easy to incorporate into a regular skincare routine.By continuing to receive treatments, you can work toward improving your skin texture.. Since you can enjoy the treatment in a relaxed state, it’s highly recommended as a treat for yourself—whether you’re looking to “pamper yourself” or “be soothed.”
