In the Russian lip technique, the hyaluronic acid filler of choice is vertically injected into the lip base and placed along the outside edge of the lip. This technique, therefore, forms an upward turn shape by lifting or flipping the lip. As a result, your lips will appear flat rather than having outward volume. Many clients prefer this procedure because it creates a more natural appearance.
Fortunately, dermal fillers work very quickly. However, it is important to note that these injectable treatments take time to integrate into your tissues. Consequently, your dermal filler may take up to two weeks to fully settle into your face.
