// Sample Code. Manipulating Face Beautification Effects
ARGSession *argSession = [[ARGSession alloc] initWithARGConfig:argConfig error:&error];
// Set a Specific Face Beautification Effect Level
[[argSession contents] setBeauty:ARGContentItemBeautyFaceSlim value:0.7f];
// Set 16 Face Beautification Effects at the Same Time
float beautyValue[BEAUTY_TYPE_NUM];
defaultValue[BEAUTY_TYPE_VLINE] = 10.f;
defaultValue[BEAUTY_TYPE_FACE_SLIM] = 90.f;
defaultValue[BEAUTY_TYPE_JAW] = 55.f;

Swift
// Sample Code. Manipulating Face Beautification Effects
if let session = argSession, let contents = session.contents {
// Set a Specific Face Beautification Effect Level
contents.setBeauty(.faceSlim, value: 0.7)
// Set 16 Face Beautification Effects at the Same Time
var beautyValue: [Float] = [
10.0,
90.0,
55.0,
-50.0,
