Make sure that the label on the underside of the plate matches the medication you are testing. Place the disk in the middle of the appropriate quadrant on one of the agar plates. See Figure 4 for an example. Using the forceps, press down gently to ensure good contact between the agar plate and the disk.

Lesions occur primarily on the face, neck, upper back and chest.4 When assessing the severity of the acne, one needs to consider the distribution (back, chest, upper arms), type and number of lesions (comedones, papules, pustules, nodules) and the presence or absence of scarring (Table 1).2,3
The dark noticeable tips are not caused by the presence of dirt. Sebum contains melanin pigment, and when it makes contact with the air, it oxidizes, resulting in the dark hue observed in these open comedones. Therefore, washing more rigorously is of no use, and can actually harm the skin even further.
Risk factors for the development of acne, other than genetics, have not been conclusively identified. Possible secondary contributors include hormones, infections, diet and stress. Studies investigating the impact of smoking on the incidence and severity of acne have been inconclusive. Sunlight and cleanliness are not associated with acne.
Oral are best used with topical retinoids and benzoyl peroxide. Studies have found that using topical benzoyl peroxide along with oral antibiotics may reduce the risk of developing antibiotic resistance.
Drink a glass of warm water with a teaspoon of honey and lime juice daily in the morning on an empty stomach. This will purify the system by flushing out the toxins from the body and maintain the pH balance of the skin, thus curing pimples and acne.
The milk and honey combination makes for a wonderful acne facial. Milk cleanses the skin and keeps it bacteria-free (58). It nourishes the skin and exfoliates it to make it soft and supple. It also renders a natural glow to the skin (59).
In the 16th century, the French physician and botanist François Boissier de Sauvages de Lacroix provided one of the earlier descriptions of acne. He used the term “psydracia achne” to describe small, red and hard tubercles that altered a person’s facial appearance during adolescence, and were neither itchy nor painful.
Most experience acne on the face area, but the neck, chest, upper back and shoulders are commonly affected as well. Acne can cause scarring and and even psychological distress, especially in teenagers who are already stressed about acceptance with their peers and their schoolwork.
I used dermalmd blemish serum on a giant-ass pimple that I had (guiltily) popped because it was too enormous and painful for me to deal with. While popping it was a mistake, using the after serum on it helped it heal within basically two days. It reduced in redness, size, and swelling, and then it just healed fully. I still have hyperpigmentation there because that’s just how my nasty skin works, but honestly I can’t think of anything else that would have worked better. The trick for that pimple was to constantly re-apply the serum, like every few hours. It is a tiny bit sticky, but not greasy, and doesn’t give me more breakouts. I’ll keep using it for future explosions.
Sulfur. In combination with other substances such as alcohol and salicylic acid, sulfur is a component of many over-the-counter acne medications. It usually isn’t used by itself because of its unpleasant odor. It’s unclear how sulfur works, but it has only a marginal benefit in most cases.
Lemongrass oil, like the other oils mentioned above, possesses antimicrobial properties and can eliminate the bacteria that is aggravating the acne (17). It also acts a skin toner and astringent and balances the sebum production.

This animation shows the setup and use of the Kirby-Bauer disk-diffusion method in a clinical setting. The bacterial growth conditions are different in this science fair project, but the basic concept is the same as in this animation. The last animation section covers how to interpret the results of the test, which will be particularly useful for your science fair project.
