Winning formula: 5 face slimming tricks for flawless results

    1
  1. Start subtle: To achieve the best face slimming trick, you need to apply your edit subtly. Avoid over-editing or over-slimming your face, as it can make it appear less authentic and give the impression of artificiality. Always know that less is more when it comes to face editing.
  2. 2
  3. Consider face shape: Before you start editing your images, you should know what your natural bone structure looks like. Having this information and working with your natural bone structure can enhance your picture for the better.
  4. 3
  5. Match your lighting: While editing your photo for a slime-looking face, ensure every edit applied matches the original photo lighting. That way, it doesn't appear fake or overly edited. Whether you're using AI or manually editing your pictures, the edit should blend with the lighting.
  6. 4
  7. Check different angles: Always zoom out to see the overall effect, spot your errors, and fix them. However, it's essential to zoom in and check for pixel distortion or unnatural blending along the edges, particularly around the jawline and neck. Additionally, viewing the photo in both landscape and portrait orientations can help expose flaws.
  8. 5
  9. Save original files: Before you start editing your photo. Always keep or save an unedited version of the image you want to edit. This serves as a safety backup to adjust your images in case of error and provides a good way to compare edited images with originals.
