2. Add a variable to the script. "[SerializedField] private UISkinner _variable = null;"
3. Call the "SetSkin" function and specify the required Skin Style index ("Current Select Style" number in Skinner inspector) as an argument.

public class SampleScript : MonoBehaviour
{
    [SerializedField] private UISkinner _yourSkinner = null;

    private void Start ()
    {
        int yourFirstApplySkinStyleIndex = 0;
        _yourSkinner.SetSkin (yourFirstApplySkinStyleIndex);
    }
    
    public void ChangeSkinStyle ()
    {
        int yourNextSkinStyleIndex = 0;
        _yourSkinner.SetSkin (yourNextSkinStyleIndex);
    }
