The principle of oval face plastic surgery is to make the chin tissue cells grow, differentiate, and transform along the tissue engineering collagen grid to form new tissue, thereby achieving plumpness and lengthening of the chin. Traditional prosthetic chin augmentation can better solve static beauty, but when the chin moves, it often gives people a sense of wrinkles and strangeness in the chin, resulting in poor visual realism. However, oval face plastic surgery can achieve the integration of bones and flesh, taking into account the beauty of movement and stillness easily.
