4D Skin Rejuvenation with Lasers
4D is a protocol used to tighten the skin, eliminate surface irregularities, open fine wrinkles, reduce the depth of the nasolabial fold, and stimulate collagen synthesis.
In the treatment, 4 different protocols are used: smooth, frac 3, piano and superficial peeling, and 2 wavelengths, nd-yag and erbium-yag. The processing time is approximately 50–60 minutes. It is an extremely effective method for rejuvenating the face and neck area. Since the procedure is painless, there is no need for anesthesia. It is recommended to have four sessions, one month apart. Much more effective results are achieved when supported by mesotherapy or PRP.
Step 1 Smooth Mode: It is a non-ablative Erbium-yag application to open the nasolabial folds by stimulating collagen production using mild heat inside the mouth.
Step 2 Frac 3: Following the smooth mode, this treatment restores the skin by targeting deeper lines and pigments with 3-dimensional fractional Nd-yag shots. When laser light spreads across the epidermis, the top layer of skin, it selectively heats areas of skin damage and becomes fractional when it touches imperfections.
Step 3 Piano: Ultra-long pulse Nd-yag is used in the piano mode, which is the 3rd step of the 4D protocol. Laser energy concentrates in the lower layers of the skin and causes tissue heating. High temperatures in the deep layer of the skin stimulate collagen production and tighten the skin.
Step 4 Superficial Peeling: The last step, peeling, is the application of erbium-yag to give the skin a smooth and shiny appearance.
