If you dream of making yourself beautiful through the use of make-up, or other beauty enhancements, it usually means you lack confidence in your present self.
You can help yourself by reading a self-improvement book. External appearances are superficial. However, this does not mean you can let yourself go and not care for your body. You should eat a healthy diet, exercise for health and loose excess weight. If you’re smoking, drinking alcohol or using substances, ditch the unhealthy habits. Seek help from A.A. and other professional associations.
If you’re a male and dreamed of making yourself look handsome, it means the same things as the above, just that you’re a male.
