Dear,
According to your horoscope you are Gemini ascendant. Your functional malefics are Rahu and Ketu. Currently you are going through Mars – Venus dasha.
Moon in your case represents your face and its parts. Moon is posited in the fourth house in the sign of Virgo. Dispositor of Moon, i.e. Mercury is weak by placement (posited in the 8th house). Currently transit Rahu and transit Ketu are exactly afflicting natal Moon and hence making it weak which causes acne problems.
You may wear a Natural Jyotish Pearl to resolve your issues of acne.
Thank You
