2. Use an exfoliating acid to de-gunk your pores. When you think about an exfoliant, you probably think of a cleanser with beads or granules. These are called physical exfoliants, and while they’re great for sloughing away dead skin, they can be irritating to acne that’s already present on the skin. And, even worse, they inadvertently spread bacteria across your face, causing more breakouts. Acid exfoliators (also referred to as chemical exfoliants) sound strong and scary, but in reality, they’re phenomenal for your complexion. They work like little Pac-Man on your skin, helping to devour dirt, debris, and dead skin cells that clog your pores. The all-star chemical exfoliators for acne are glycolic acid and fruit-based enzymes, such as papaya and pumpkin. Just be careful not to over-exfoliate, which can dry out the skin and lead to the overproduction of oil and, therefore, more acne; two or three times a week should suffice.
Hyperkalemia is a potential dangerous adverse effect from spironolactone; however, a 2015 large retrospective study of healthy women aged 18-45 years confirms potassium monitoring is unnecessary for these patients while taking spironolactone.  Plovanich et al found the rate of hyperkalemia in patients taking spironolactone is equivalent to the minimal baseline rate of hyperkalemia in this population, and, of the hyperkalemia cases, none was clinically significant.
Recent studies conducted by dermatologists in 2012 show that green tea has a positive impact on acne, when applied externally. Green tea has an antioxidant known as epigallocatechin-3-gallate (EGCG). It was observed that EGCG reduced inflammation, sebum production and bacterial growth on pimple-prone skin. Place 2 teaspoons of organic tea leaves in 1/2 cup of fresh boiling water. Steep for 5 minutes; strain the leaves and let the mixture cool. Then use a cotton pad to apply it on your face. You may also put it inside a spray bottle and spray it on. Leave it on overnight.

Try a light treatment. Unlike painful laser treatments, light treatments use milder pulses of light fired off by a specialized wand to help kill bacteria. Certain colors of light (including red, green, and blue) have shown to have a positive effect on killing acne. Ask your dermatologist if getting a light treatment is a good choice for you.

If you have been taking topical retinoids while you were pregnant do not immediately assume the worst. Findings from a study of a large number of pregnancies where the mother was exposed to topical retinoids, along with data from studies looking into the absorption of retinoids after use of topical cream on the face, suggests that you have not exposed your child to any extra risks. However, as retinoids are known to cause birth defects, it is important that you discuss this issue with your doctor.
