近年來科技的快速發展，人類的知識日益提昇，一些科學家發現，人類不斷耗盡地球資源將會促使人類本身快速走向滅亡之路。科學家們認為自然界是一個能量的世界，耗盡能量，自然界就會滅亡。而在現代的社會裡，化妝品制造業是一個快速成長的行業，其用來制造化妝品的原料卻主要是來自石油能源，為了滿足現代人對美的渴望，而加速耗盡地球能源，其代價是何等之高。所以，現在已有一些化妝品公司開始使用其他替代原料來製造化妝品。坊間美容保養品也有人嘗試使用其他更天然並且可回收的原料來製造。綜觀市場上，保養品替代原料雖然很多，但真正運用天然水果來製成保養品的卻極為稀少，而且天然水果所製成的保養品已被證實對皮膚具有美白和保濕等功效。因此本研究希望利用生活中容易取得的天然水果，將它的果汁、果肉、果皮等來加以利用閉發，自己動手DIY創意設計一系列的天然美白保濕保養品，本研究將其取名為“素淨”(Su Gin)保養品，意指“素雅乾淨”的意思。除了可以滿足現代職業婦女愛美的需求外，同時也希望開發出一套能在台灣保養品市場上暢銷的天然美容保養聖品。

In the recent years, technology has been growing in a fast speed, knowledge has been cumulated quickly. Some scientists have found that due to the fast consumption of earth's resource, human beings are doomed to he extinct in the future. Scientists think that the world is an energy world, if we have consumed all the energy we have, the world will end soon. In a modern society, cosmetic industry is a rapid growing industry. But the materials that are used to make cosmetic products are coming from the oil. In order to meet the need of desired beauty, human beings have rapidly consumed the natural resource. The cost is way more too high. Therethre, some of the large cosmetic companies have tried to replace the original ingredients of cosmetic product by some natural materials, and other private makers also tried some recyclable materials. If we take a closer look at the cosmetic product market, we can find that more and more natural materials have been used, but it is still rare to use natural fruits to make cosmetic products, and it has been proven that these products made of natural fruits are more effective in whitening skin and in keeping skin moisture. This research is hoping to create a series of Cosmetic products made of natural fruits, including fruit juice, fruit flesh, and fruit skin by the way of doing it yourself, and name it
