In the last issue, we introduced the causes of skin aging and introduced radio frequency beauty equipment to everyone. Let's talk about HIFU in this issue
Although both Radio Frequency and HIFU are the main anti-aging devices, their attributes, users of the products, treatment courses, etc. are very different.
Treatment principle
Ultrasonic knife, the professional term is "High Intensity Focused Ultrasound (HIFU)". Using HIFU equipment, the ultrasound is precisely focused on the dermis and fascia layer (SMAS) of the skin. The heat generated by the focused ultrasound stimulates the proliferation and reorganization of collagen, effectively achieving a firm contour and the effect of smoothing lines.
Treatment depth and temperature
The depth of the HIFU can be adjusted according to the individual's skin, generally 1.5mm-4.5mm, the deepest can reach the fascia layer, the treatment effect is deeper.
The treatment temperature is up to 70 degrees, and it can promote the regeneration of new collagen under high temperature.
The depth of the RF is generally less than 3mm, and the deepest reaches the dermis. The treatment temperature is generally around 55 degrees, which is very effective for smoothing wrinkles.
3. Treatment time
HIFU: Generally, it depends on the patient's skin aging degree. A full-face HIFU is used to remove 30 minutes of anesthetic time. The treatment time is generally about 60 minutes.
RF: According to the standard of the whole face, the treatment time will be shorter than the HIFU, about 30-40 minutes
4. Continuous effect
HIFU: The effect of HIFU is generally felt in about one week to two weeks. At first, it feels the lifting and firmness of the skin. After about 2 months after the operation, with the regeneration and reorganization of collagen, it can be Obviously see the phenomenon of reduction of wrinkles, smooth skin, tightening of sagging parts, etc. After multiple treatments, the effect generally lasts for 4-5 years
Radio frequency: Compared with HIFU, the presentation is slower, mainly because the parameters of the radio frequency are not as high as the HIFU, and the postoperative effect is relatively slow. Generally, after two weeks, the skin can feel the changes in lifting and firming. , About three months after the operation, you can see the signs of thinning of fine lines and other wrinkles, the skin's collagen feeling, the postoperative effect will generally last about 3 years
5. Suitable for
HIFU: suitable for subjects with obvious symptoms of aging, such as: patients with deep wrinkles, eye lines, and horoscope lines, or patients with more fleshy faces
Since the deepest level of the HIFU can reach the fascia layer, the fascia layer is attached to fat. If you want to thin your face or smooth wrinkles, you must first start from the fascia layer, that is to say, the fascia layer must be lifted up to achieve this. Firming and lifting effect
Radio frequency: suitable for patients with deep eye wrinkles and serious loss of collagen
In addition to eye treatments, radiofrequency has obvious effects on collagen regeneration. It is strongly recommended for girls with sunken skin and serious collagen loss to try it. Because thermage acts on the fat layer, it can tighten the fat and stimulate the reorganization of collagen to make the skin more elastic
6. Postoperative maintenance of contraindicated subjects
Regarding the contraindications, there is little difference between an ultrasonic knife and a radio frequency. They are not suitable for filled areas, areas with open wounds, and areas with over-sensitive acne muscles.
Since both are high temperature treatments, moisturizing and hydrating after the operation must be indispensable. If you apply a facial mask, it is recommended to apply once every two days. If you inject hydration, it is best to choose a water light injection. In addition to hydrating, sun protection is also very important. Since the skin has just finished high temperature treatment, the skin's sensitivity and immunity are very low, and it is easy to be invaded by ultraviolet rays, so remember to apply sunscreen every day!
The above is all about the difference between ultrasonic scalpel and radio frequency
Ladies, you can choose according to your skin type and symptoms of aging.
