Electric toothbrushes use motors to move the bristles rapidly usually between a few thousand times a minute to approximately 10,000 to 12,000 times per minute ( 1 Hertz (Hz) is 1 movement or cycle per second). This high frequency works well for dentists as it is anti-bacterial and helps remove plaque. For cleaning your face, however, that’s too high. You’re looking for a gentle pressure cleaning that still has anti-bacterial and anti-inflammatory properties. Machines, like Aesthetic Science’s Epiwave® UltraSonic Machine, that use lower ultrasonic frequencies (20kHz and up) attain the cleansing and exfoliation that also prepares the skin for the facial treatment ahead.
Our skin is our largest organ. It has three general layers: the epidermis, the dermis, and the subcutaneous fat (or lipid) layer. Each of these layers breaks down into sublayers. Skincare is mostly focused on the epidermis which breaks down into five different sublayers. The top layer, the stratum corneum, is where the dead skin cells collect and need to be cleaned and exfoliated (removed).
Unfortunately for us in the Sunshine State, the sun is the biggest cause of skin damage. Premature aging, wrinkles, hyperpigmentation (dark spots and uneven skin tone), and skin cancer are all aggravated by prolonged sun exposure. What’s worse is that many skin treatments, when done too frequently to the skin, especially sensitive or sun-damaged skin, can add to the damage instead of merely leaving a clean slate. Microdermabrasion, peels, dermaplaning, and others all remove layers of the epidermis, which can be good when done in moderation.
Many facials are done by hand, however, some steps can be performed by machines. In the case of the Epiwave®, it is a three-step process that starts by gently deep pore cleaning and exfoliating without irritation using low-frequency ultrasound. The modality, or function, of the machine can then be switched to the infusion (or sonophoresis) step using the treatment and/ or serum so that any molecules that are too large and require a pathway through the lipid portions of the stratum corneum, can be transferred using ultrasonic frequencies. It is this low- frequency ultrasound (again just above 20 kHz) that enables dissolved gases in the lipid regions between skin cells to bubble up and start to move, creating pathways. This is how to get the antioxidants, nutrients, and hydrating products that do the most help to the cells where they are needed while doing the least, or no damage, to the upper layers. I call that a win- win. The third step heals the cells by using a low-level current in the Hz range to restore the natural electrical potential of the cell membrane. You finish off the facial the same as before, “sealing the deal” with moisturizer and sunscreen.
Everyone ages, and without proper protection, the more sun your face is exposed to, the more your skin ages. There are many machines and products available in salons and spas, and for home use, that can help protect against and slow down the aging process. Ultrasonic machines are just one, but they are effective and do not cause any additional damage. Ask your esthetician/skincare specialist about this technology and see how it works for yourself!
