I.INTRODUCTION

A. Background of the Study

Orange is a citrus fruit that belongs to the family Rutaceae. It is also called sweet orange, to distinguish it from the related Citrus aurantium, referred to as bitter orange. The sweet orange reproduces asexually (apomixis through nucellar embryony); varieties of sweet orange arise through mutations. Orange tree is an evergreen plant that can reach 30 to 33 feet in height with a crown that can reach 20 feet in diameter. The leaves are oval in shape, have fine rounded teeth on the edges and are alternately arranged on the branches. The flower is white in color and it blossoms in spring.

Botanically speaking, fruit of orange tree belong to the group of berries. It has peel on the surface which protects juicy fresh in the middle of the fruit. Flesh is usually divided into 10 segments. The size and sweetness of the fruit as well as the color of the peel and flesh depend on the variety.

There are over 600 varieties of orange trees that can be found in tropical and subtropical parts of the world. Oranges originate from Southeast Asia. Cultivation of oranges started 2500 years BC and were introduced to Europe in 15th century and soon afterwards they were shipped to the South America which became the greatest manufacturer of oranges in the world.

Oranges are rich source of vitamin C, vitamins of the B group and minerals such as calcium, magnesium, potassium and phosphorus. Due to high content of vitamin C, orange can improve immune system, facilitate absorption of the iron and accelerate wound healing. Aside from the health benefits, oranges have also numerous uses such as natural repellents, cooking and cleaning uses as well as for beauty treatments and applications.

B. Review of Related Literature What causes pimples? Pimples, also known as spots or zits, are part of acne. They are most likely to occur around puberty, but they can happen at any age. During puberty, hormone production changes. This can cause the sebaceous glands located at the base of hair follicles to become overactive. As a result, pimples are likely to appear during the teenage years and around menstruation, for women.

Acne vulgaris, the main cause of pimples affects over 80% of teenagers. After the age of 25 years, it affects 3% of men and 12% of women. Pimples happen when pores become clogged with sebum and dead skin. Sometimes this leads to infection and inflammation (https://www.medicalnewstoday.com).

Dapon (2011) said that a pimple or acne vulgaris is a skin disease commonly affecting the oil-secreting glands of the skin. This type of acne is the concern of many adolescents because it often mounts to break-outs in the individuals face, neck and shoulders. This further leads to dented scars.

There have been numerous claims about the causes of pimples but medical doctors agree that hormones are the main cause of the said skin disease. This is due to the increased sebum released by the sebaceous glands when an individual reaches puberty. The excess sebum gets clogged in the skin pores that develop into pimples. Because of this, the demand for an effective and safe pimple remover became expectedly high. Since pimple is usually an infection, a bacterial problem, the early answer was antibiotic medications. However, Hörfelt (2009) said in her dissertation “Photodynamic therapy for treatment of Acne vulgaris in clinical studies: dose response and mode of action" that antibiotics were used too widely that some pimple gained bacterial resistance. In her experiment, subjects showed no clinical response and experienced no side effects, gaining no new changes. Antiinflammatory activity of Citrus sinesis is due to the presence of polymethoxyflavones. Citrus sinesis (orange) peel extract contain bioflavonoids, including polymethoxylated flavones (PMFs), which have anti-inflammatory, antioxidant and hypolipidemic effects.

Orange Peel

The peel has anti-bacterial and anti-microbial properties which make it great for treating acne and oily skin. It also works as a skin lightening agent and can do wonders for marks on the face and pigmentation. Besides its medicinal, more obvious properties, face packs with orange peel can also be used as face cleansers and leave the skin looking refreshed. Orange peel is best used in powder form (https://food.ndtv.com).

Phenols in Orange Peel Kill Acne-Causing Bacteria

Pimples are basically bacterial infections. Specifically, a kind of bacteria called the Propionibacterium acnes (P. acnes) is the culprit. These microorganisms live on our skin. They thrive in clogged skin pores, causing inflammation that results in those unsightly zits. Fortunately, extracts from bitter orange (Citrus aurantium) peels have been found to be effective against P. acnes, chiefly due to the phenolic antioxidants. One study even concluded that the antibacterial action of orange peels is as potent as that of antibiotics. While studies have not been conducted on the antibacterial effects of other types of oranges, since all orange peels contain antioxidants, the effect will be similar.

Nobiletin in Orange Peel Makes Your Skin Less Oily

Sometimes, the oil glands in our skin make excess oil or sebum. This can lead to clogged pores and acne. If you’re prone to greasy skin, consider putting those orange peels to work. Studies have found that nobiletin, a flavonoid found in orange peels, can actually reduce sebum production.

Vitamin C in Orange Peel Fights Inflammation Having a pimple is bad enough. Inflammation just makes it worse. But this is typical with the P. acnes infection during an outbreak. It causes reddening and swelling, adding to your acne woes. Luckily, orange peels actually have flavones with anti-inflammatory properties. Nobiletin is particularly potent plus vitamin C is a known antioxidant that reduces inflammation. In fact, the peel has more vitamin C than the flesh.

C. Statement of the Objective This research aims the following: 1. To determine the effectiveness of orange peel in eliminating pimples; and 2. To come up with the most effective pimple solution through different preparation methods.

D. Statement of the Problem Specifically, this research seeks to answer the following questions: 1. Does orange peel effective in eliminating pimples? 2. What preparation method is the most effective in eliminating pimples?

E. Statement of the Hypothesis The properties of orange peel extracts as an anti-oxidant can eliminate pimples for 2-3 weeks.

F. Significance of the Study The study will generate useful information for recommending the most effective preparation method of orange peels in eliminating pimples. Specifically, it will be useful to everyone suffering from pimples particularly teen agers or adolescents that cannot afford to buy commercially sold cosmetic solutions.

G. Scope and Limitations The conduct of the study will concentrate only on the following: 1. Use of sweet orange peels readily available in the market; blended orange peels and milk; and dried orange peels for several days. 2. Each treatment will be applied by three different persons twice a day within 15 days for better comparison of results.

H. Definition of Terms 1. Orange peel – healthiest part of the fruit. It is rich in flavonoids like hesperidin, polymethoxyflavones (PMFs), and other phytochemicals. Orange peel contains higher amounts of certain nutrients like vitamin C than its flesh. 2. Pimple - a small pustule or papule that develop when sebaceous glands, or oil glands, become clogged and infected, leading to swollen, red lesions filled with pus.
