How often?

The Acne.org Neck Regimen should be performed both in the morning and in the evening, about 10-12 hours apart.

Step 1 - Acne.org Cleanser

# How Why
1.1 Dispense 1 pump (about 1/2 teaspoon's worth - 1mL) of Acne.org Cleanser into your palm and get a good lather going. Using a generous amount of Acne.org Cleanser will allow you to generate a good lather. The more lather you generate, the more easily your hands will glide across your skin, thereby reducing irritation.
1.2 In the shower or at the sink, gently wash your neck for 10 seconds or less and with a gentle touch. Rinse. Cleansing is necessary because it removes surface oils which allows the Acne.org Treatment (Benzoyl Peroxide - 2.5%) and/or Acne.org AHA+ (Glycolic Acid - 10%) to penetrate, but you can easily achieve this goal with bare hands and only a few seconds of washing. Washing for this short a period of time reduces irritation and is one of the most important steps in The Acne.org Neck Regimen.
1.3 Gently pat your neck dry. Do not rub. You may not get your skin completely dry with a towel this way, but that's ok. The remaining wetness will air dry quickly. Anything which rubs, scratches, or scrubs the skin can cause irritation. Stay very gentle with your towel.
1.4 Wait until your skin is completely dry. Letting your skin dry allows the Acne.org Treatment (Benzoyl Peroxide - 2.5%) to better absorb.

Step 2 - Acne.org Treatment (Benzoyl Peroxide - 2.5%)

# How Why
2.1 Wash and dry hands. This helps remove any oils that may have accumulated on your hands. Exposure to oils can aggravate acne.
2.2 Dispense 1 pump (about 1/2 teaspoon's worth - 2mL) of Acne.org Treatment (Benzoyl Peroxide - 2.5%). Using an extremely generous amount of benzoyl peroxide is crucial. When in doubt, use more! 

Note: This refers to only after you have worked up your dosage to the full amount (1 pump - about 1/2 teaspoon's worth - 2mL). If you have sensitive skin, start with only 1/2 pump (about 1/4 teaspoon's worth - 1mL) for the first week and apply only once per day. By week 2 you should be able to move up to the full amount (1 pump - about 1/2 teaspoon's worth - 2mL) and start applying twice per day.
2.3 Apply very gently, allowing your fingers to glide over the neck until the Acne.org Treatment (Benzoyl Peroxide - 2.5%) is more or less absorbed. Staying super gentle reduces irritation.
2.4 Wait until your skin is completely dry. Feel free to do other normal daily activities during this time. Benzoyl peroxide oxygenates skin, and dries and peels inside the pore. It is important to give it the time it needs to properly medicate and treat acne.
  Benzoyl peroxide can bleach fabric. This is the most challenging part of this regimen. If you are using benzoyl peroxide in the morning, you may want to wear a white undershirt. Once you are completely clear, try eliminating benzoyl peroxide from the morning routine. Still keep applying the glycolic acid twice a day but only apply benzoyl peroxide at night and see if you can stay clear with just once daily benzoyl peroxide application. This works well for some people with less severe acne.

Step 3 - Acne.org AHA+ (Glycolic Acid - 10%)

# How Why
3.1 Wash and dry hands. This helps remove any oils that may have accumulated on your hands. Exposure to oils can aggravate acne.
3.2 Dispense 1 pump (about 1/2 teaspoon's worth - 2mL) of Acne.org AHA+ (Glycolic Acid - 10%). The neck requires a lot of glycolic acid to properly treat.
3.3 Apply very gently, allowing your fingers to glide over the neck until the glycolic acid is more or less absorbed. Wait for the glycolic acid to dry before dressing. Staying super gentle reduces irritation.
