Hi, you don't say specifically which acne medicines you have tried.
Acne usually responds well to a course of oral antibiotics such as Oxytetracycline 250mg twice daily and a topical retinoid cream such as Differin (adapalene 0.1%). Clinical improvement may be seen after 4-8 weeks but it may take 12 weeks for total clearance.
Female acne patients may also respond well to taking an anti-androgen contraceptive pill like Yasmin or Diane35. Non-hormonal anti-androgens such as Spironolactone may also be used.
Aloe Vera moisturises the skin, but is not particularly useful in acne prevention.
