I'm 30 and have had acne since about age 13. Mild on the face, moderate to significant on my shoulders/back.
I've tried it all.... literally.
calendula, no effect.
vegan diet, no effect.
sulfa washes, no effect.
Retin A micro and other vitamin A derived topicals, no effect.
salicyclic acid topicals, no effect.
benzyl peroxide topicals, no effect.
the above two combined, no effect.
the above two with triclosan topicals, no effect.
koumbacha tea, no effect.
tea tree, no effect.
frequent light washings, no effect.
1st morning's urine, gross yes, no effect.
all of the cycline drugs (tetra, doxy etc), no effect.
high intake of water per day, no effect.
Exposure to UV/sunlight, no effect... as a microbiology major, I'm aware of its antibiotic effect. On mortal bacteria that is.
bactrum antibiotic, pill form... worked and worked well... unfortunately it gave me the worst gas ever and my marriage mandated I get off of it ;p.(Ever been to Yellowstone and seen the sulfur pools? I could have passed for one).
Accutane... I refuse. Way too many side-effects, and I'd rather have backne than commit suicide or any of the other several hundred side effects.
There's probably a few other's I haven't listed... no effect... glycerin soap, other natural soaps, nutrogena, every 'acne' kit/soap at wal-mart, oatmeal...
nothing... not applying soaps, no effect.
Anywho, looking for any other options anyone can think of.
