This should bring down the swelling, as it slows down blood flow to the area. Either apply ice directly to the pimple or cover it in a thin layer of gauze or towel. Some makeup experts claim that eye drops, at least the ones that reduce redness in the eyes, can be helpful in reducing redness and signs of irritation in acne. Drop a few eye-drops onto a cotton swab and apply as necessary onto the pimple(s). Because cold also helps reduce inflammation in acne, place the Q-Tip soaked in eye-drops into the freezer for an hour before applying. The cold Q-Tip will soothe as it reduces inflammation. Antihistamines suppress the swelling effect in the skin tissue of people. Most of these remedies can be ingested in pill form, but some can be consumed as tea or used as a topical agent. These should offer a reduction in redness. Natural herbal antihistamines include:  Stinging nettle. This may sound weird, because touching nettles in the wild can produce a rash not unlike small pimples. Some doctors, however, recommend taking a freeze-dried preparation of stinging nettle, which is known for its ability to reduce the amount of histamine the body produces.  Coltsfoot may be effective as a natural antihistamine. Europeans have a long history of using the plant to cure skin conditions. The leaves can either be ground up into a paste or coltsfoot extract can be ingested in pill form. Basil may also work as a natural antihistamine. Heat a couple sprigs of basil leaves up under some steam and apply gently to the hives. Basil may help reassure the body that the foreign agent causing the hives is not something it should be fighting.
Put ice on the affected area. Use eye-drops on the affected area. Try some natural antihistamines.
