When doing a retouch only apply to?

When doing a retouch, apply adjustments only to the areas that need correction, such as blemishes, discoloration, or distractions. Use layer masks or selective editing tools to ensure the retouching is subtle and blends seamlessly with the surrounding areas. This approach helps maintain the natural look of the image while enhancing its overall quality. Always keep the original texture and details intact to avoid an overly edited appearance.
