Good daily acne care will help to improve skin follicles. Eating certain foods does not cause acne, therefore restricting the diet is not helpful. Excessively scrubbing does not help either, and can even be more irritating to the skin.
For best comedones care, use a mild soap or scrub cream. This will help to remove excessive sebum and dead skin cells.
Oil-based makeup should not be used, since makeup oils can clog in the follicles. Water-based makeup can be used instead, as they are non-comedogenic.
