However, treating nasolabial folds requires a detailed understanding of the effects of aging on the facial structures. In the world of aesthetics, one of the most requested enhancements is for the effacement of nasolabial folds. Nasolabial folds and smile lines, are they the same thing? However, in other cases, Restylane Lyft’s highly viscous, cohesive formula can be injected into the cheeks to lift the lower face. This wrinkle filler targets the folds directly, plumping them and filling them out. ![]() These products are specially formulated to maintain facial expressions in the most dynamic regions of the face, for subtle and natural enhancement. Restylane Refyne and Defyne are newer additions to the Restylane portfolio, which are both indicated for the correction of nasolabial folds. Restylane is the classic choice for wrinkle filling, producing excellent results and having an established efficacy and safety profile. 1.Restylane offers a various dermal fillers for the treatment of nasolabial folds. Therefore, it is safest to inject fillers carefully and slowly. However, there may be a higher risk of embolization. It was confirmed that at 6 months, it was well maintained. There may be slightly more swelling, but it goes away within a week. It was performed in 20 patients, and there were no complications. When the muscle was strong, botulinum toxin type A was injected into the levator labii superioris alaeque nasi, with 2 units each on both sides, to reduce the duration of upward migration of the filler ( Fig. The total injected amount was 1.0–1.5 mL per side. A small amount of filler (about 0.03–0.05 mL) was injected during the application of each linear threading technique. Subsequently, a low-particle-elasticity and high-cohesiveness filler (YVOIRE Y Solution 540°) was injected into the superficial fatty and subdermal layers using linear threading and fanning techniques. Deep pyriform space was filled, and the deep fat layer was also injected into the filler (YVOIRE Y Solution 720°) using linear threading and fanning techniques. Next, a high-particle-elasticity (which is a characteristic of biphasic fillers) and high-cohesiveness filler (YVOIRE Y Solution 720°, LG Chem, Republic of Korea) was injected into the deep pyriform space, immediately above the periosteum, with the retrograde linear threading technique using a blunt cannula and then into the supraperiosteal layer. The vertex of the triangle was punctured using a 25-gauge needle. The line between the alar base (which becomes the base of the triangle) and the oral commissure (which becomes the vertex of a triangle) was connected. ![]() ![]() Therefore, to address this disadvantage, the author introduces a multilayered injection technique.įirst, the entry point was anesthetized with an infraorbital nerve block. 2, 3 Moreover, bolus injection has the disadvantage of rapid spreading because the filler is in a gel form. Injection is typically performed on the inner layer of the NLF, and the shape is not well maintained in the case of fillers. However, inside the NLF, there is a dense fascia with a thin superficial fatty layer, and due to the presence of a malar fat pad on the outer layer, the superficial fatty layer is thick. The simplest method of filler injection is most commonly used. 2 Methods to resolve the NLF include pyriform aperture implantation, midface lifting, and filler injection. 1 There is a difference in tissue density inside and outside the fold, with the fat layer on the upper part of the fold being relatively loose, while the inner layer is dense and tight. The NLF is caused by the continuous movement of the lip elevator muscles and attachment of the muscle fiber to the skin. The nasolabial fold (NLF) is a natural wrinkle in the face, observed during smiling.
