Foods are the biggest source of zitness- and the prior poster is right on colonics. Your skin on your face shows exactly what is going on with your digestive system- what sort of materials you're absorbing and having trouble eliminating.
When I went on a paleo diet, I was more or less completely zit-free- I focused on fruits, veg and meats, and eliminated dairy products except unsweetened yogurt.
If you want a good help against zittage, grab some bentonite, montomorillite, or equivalent clay and use it to help eliminate the issues your skin is trying to push out. You can also use it as a drink once or twice a day to cleanse your colon- it's very effective at helping with eliminating
colonic plaque and the materials that get stuck in it.
I've used coffee
colonics myself, and it does have some rather interesting effects- major urpage when your
colonic colony is nasty (fx, when digesting chips, candy, white bread products all the time), but a feeling of a speeding heartbeat and then relaxation as water is sped into your bloodstream. (Coffee
colonics is 2-3 tbsp good strong coffee mixed into 2quarts (a little less than 2 liters) of water.) Among other nutrients, coffee is rich in magnesium, which helps your health.
Acne is also very much related to liver health. If your liver can't ship it out into your bowel for elimination, 'it'- whatever your insides need to shunt out, like excess transfats, dead cellular material and non-body-friendly substances, it gets backed up in your circulatory and lymph system and excreted via other methods. From order of preferred to unpreferred by the body- feces, urine, pores. If you especially get zits about the nose, that's a sign of the liver stuffed to the brim. There's major bloodflow to the brain just behind the nose, so a lot of material has the potential to accumulate there.
If you wanna help out the liver, look up of course liver flushes, TMG (tri-methyl-glycine), foods rich in b-vitamins (dark green veg, nuts, egg yolk and meats), and give bowel and
parasite cleansing a straight look.
In my experience there's very few scrubs/washes that do anything for acne. Skin comes from within, as you might say! A bentonite/montomorillite clay mask pulls out the bads exceptionally well though, and I've used it with quick results (2-3 days and no outbreak on the zittage, the redness goes down quickly).
There's one nutrient I point people to almost hands down, every time. Vitamin D3- without adequate levels in your blood, you're just setting up your insides for a world of difficulty. I don't know anyone personally who spends 20+ minutes a day shirtless working in the garden under full equatorial sun- and that just about means I don't know anyone with adequate fat reserves of D3 (it's a product of your skin under sun exposure). And no, sun through windows is completely inadequate, there's UV filters on everything. If your scalp is flaky, if there's psoriasis, there's the source of the problem! A high concentration of vit D3 in a lotion is a very effective cure/treatment for
Psoriasis of the skin on other areas of the body (we're talking around 5,000-10,000 iu/10 grams of lotion). It's what they call a pro-hormone which firstly allows your gut to absorb the minerals you really need, gets your gut to move things along at a proper speed, closes up the gut wall to stop bacteria and yeasts from migrating into the blood stream, and..
*cough* It's used in every cell of your body. It works in coordination with magnesium and zinc. Go ahead and read up, and I definately, definately don't reccommend using it above 5,000 iu a day for more than a month without at least 200 mg of magnesium-citrate, -malate, -chloride (or other easily-absorbable combination) beside it. Magnesium oxide is absorbed poorly and gives funky side-effects, don't bother buying it.

Lastly- <3 if I were to meet you on the street, I'd look into your eyes and expression first, and the condition of your skin last. It's a mirror of internal health, but the chemical state of your biomechanics aren't that important to a person as a potential friend in everyday life. ;)
