Prerequisites

A working React Native quickstart
NosmaiCameraView has fired onReady

Apply a subtle preset

await NosmaiCameraSdk.setSkinSmoothing(0.35);
await NosmaiCameraSdk.setSkinWhitening(0.15);
await NosmaiCameraSdk.setTeethWhitening(0.20);
await NosmaiCameraSdk.setSharpening(0.15);

Parameter ranges

All four values use 0 through 1, with 0 as the disabled value. Clamp slider input before calling the TurboModule and ignore a completed Promise if the camera screen has already unmounted.

Reset beauty

await NosmaiCameraSdk.clearBeauty();

clearBeauty() clears skin beauty, makeup, reshaping, and eye color. It preserves color controls, package slots, and manual backgrounds.

Verify it worked

Change smoothing from 0 to 0.35 while the camera view remains mounted. The native preview should update without a React component remount.

Common errors

Symptom	Cause	Fix
Promise rejects before preview appears	Processing has not started	Await initialization, mount the view, then wait for `onReady`
Changes are lost after Fast Refresh	Native state and JavaScript lifecycle were reset differently	Run full cleanup and reopen the screen during development
Preview performance falls	Development tooling or multiple face features add load	Verify a Release build on a physical device
