ABSTRACT

Everyone's skin is normal to them but we generally group people in few skin type

categories in order to tend for distinct skin types. The significant first step need to be

taken in take care of the skin are to figuring out the types of the skin that we belong to.

As a way to help the process of finding out, the Skin Type Check Website is proposing

to build. Users usually don’t know their skin types and the just buy the product

randomly and the hot seller item that may give them any breakout if don’t applicable

with their skin. Moreover, if the user knows about their skin types, but they don’t know

which product are suitable with their skin types. Nowadays, mostly people buying

online, so they don’t have to go clinic or drugstore to ask for their skin types before

purchase. The objective of this system are to develop website that can tell user their

grouping of the skin types with the characteristic given. Besides, to implement the

website that user friendly where all range of age can use. And users can get the

recommendation that suitable with their skin types. Lastly, I hope this project can help

user to take of their skin when they know the type because skin not only for appearance

but also for perform essential task for body so we need to take care of them.

ABSTRAK

Kulit setiap orang adalah normal kepada mereka tetapi biasanya terdapat kumpulan

dalam beberapa kategori jenis kulit untuk jenis kulit yang berbeza. Langkah pertama

yang penting yang perlu diambil dalam menjaga kulit ini adalah untuk mencari jenis

kulit yang kita milik. Sebagai satu cara untuk membantu proses mencari,laman web

Pengesanan Jenis Kulit akan dibangunkan. Pengguna biasanya tidak tahu jenis kulit

mereka dan hanya membeli produk secara rawak dan item penjual panas yang boleh

memberikan mereka sebarang penembusan jika tidak berkenaan dengan kulit

mereka. Selain itu, jika pengguna tahu mengenai jenis kulit mereka, tetapi mereka

tidak tahu yang mana produk yang sesuai dengan jenis kulit mereka. Pada masa kini,

kebanyakannya orang membeli dalam talian, jadi mereka tidak perlu pergi klinik

atau kedai ubat untuk meminta jenis kulit mereka sebelum pembelian. Objektif

sistem ini adalah untuk membangunkan laman web yang boleh memberitahu

pengguna perkumpulan mereka satu jenis kulit dengan ciri-ciri yang diberikan.

Selain itu, untuk melaksanakan laman web yang mesra pengguna di mana semua

peringkat umur boleh menggunakan. Dan pengguna boleh mendapatkan cadangan

yang sesuai dengan jenis kulit mereka. Akhir kata, saya berharap projek ini boleh

membantu pengguna untuk mengambil kulit mereka apabila mereka tahu jenis

kerana kulit bukan sahaja untuk penampilan tetapi juga untuk melaksanakan tugas

penting untuk badan jadi kita perlu menjaga mereka.

CHAPTER I

INTRODUCTION

1.1 Background

Making the right choice about skincare start with knowing your skin type. Different

skin type is genetically but chosen the true skincare for skin is the hardest. People

usually buy the product when they gone viral or famous online. But they don’t know

whether the product is really suitable for their skin type that can make they have the

problematic skin. So that’s why the Skin Type Determine Website will be build. The

main goal of this system is to help user to know their skin type before buying the

skincare. Moreover, lately there are many e commerce websites that sell product. To

help the user know which skin type are they, user will answer the questionnaire first

then after finish, it will determine which type of the skin is the user. Then user will get

the product recommendation that suitable for them or the ingredients that been used.

2

1.2 Problem Statement

Some problems that lead the causes of this website to develop are:

• User don’t know their skin type

• User don’t get the recommendation product that suitable with the skin

• Other website does not put if the product for what skin type.

1.3 OBJECTIVES

There are several objectives to develop this system include:

To develop website that can tell user their skin type with the characteristic given

To implement website that user friendly besides give the info and

recommendation for users

To test the effectiveness of the questionnaire used

1.4 SCOPES

SCOPE OF USER

LITERATURE REVIEW

2.1 Introduction

Literature review means searching, collecting, analysing and drawing conclusion

from all debates issues raised in relevant body of literature. While, project methodology

is the approach and techniques used to complete the project. This chapter is the report

analysing the fact finding and the approaches and techniques that is going to be use in

completing the Skin Type Detection project. The fact and finding are being analysed by

identifying the current situation and the available resources.

2.2 Validation of a Questionnaire to Diagnose the Baumann Skin Type in All

Ethnicities and in Various Geographic Locations

The Baumann Skin Typing System diagnoses patients as having one of 16 skin

types based on their answers to a validated questionnaire known as the Baumann Skin

Type Indicator. The BSTI questionnaire has been tested over the last decade on

over200,000 people of various ages and ethnicities in different geographic locations

around the world. In this study, data were collected from 52,862 patients to compare

skin type prevalence between those who presented to doctor’s offices and those who

took the quiz without supervision online. The most common skin types varied only

slightly between patients that took the quiz online and those that completed the

questionnaire in their doctor’s office. This indicates that the prevalence of skin types

seen in the doctor’s office is similar to that in the general population and that supervision

is not necessary to get an accurate result on the BSTI. In addition, comparison of data

gathered in China, Korea, and the US did not show a significant difference in skin type

prevalence between Asian and Caucasian skin types. The Baumann Skin Typing System

assigns patients to one of skin types based on their answers to a validated questionnaire

known as the Baumann Skin Type Indicator. The questionnaire gives similar results

among all ethnicities. Using the Baumann Skin Type nomenclature improves

communication between physicians, scientists, researchers, aestheticians, and patients

about skin care regimen efficacy and adverse events. Because studies have

demonstrated that patients cannot properly self-diagnose their skin type, the Baumann

Skin Type should be diagnosed using a validated questionnaire for that purpose.

6

2.3 A Validated Questionnaire for Quantifying Skin Oiliness

The Baumann Skin Typing System In order to be able to correctly determine skin

oiliness, we have developed a six-item skin oiliness scale (SOS) that correlates with

sebumeter measurements. The resulting correlation was 0.54, which was significantly

different from zero (p < 0.01). This result indicates a strong relationship between the

SOS scores and the associated sebumeter measurements. This is easy to administer

questionnaire to accurately determine skin oiliness and can be useful in screening and

recruiting patients for research trials, performing outcome research, and recommending

skin care products and procedures. Our study shows that this skin oiliness scale is an

accurate way to identify and quantify skin oiliness. The primary objective of this study

was to determine if the O (oily) section questions of the BSTI could successfully

discriminate between individuals with. In many instances, it is important to determine

a patient’s level of sebum secretion, and a sebumeter is not always available. The

findings of this study indicate that the six oily skin directed questions of the BSTI have

the ability to classify individuals based on levels of sebum secretion. This can be used

to recommend skin care products, to provide data in research trials and to divide patients

into distinct groups based on sebum production in situations where a sebumeter is not

accessible. high and low sebum secretion rates as determined by the sebumeter

measurements.

and the second part, namely Part 2: Is Your Skin Sensitive or Resistant?. Part 1 of the

section has 9 questions while Part 2 has 12 questions. Each answer has its own scores

CHAPTER III

METHODOLOGY

3.1 Introduction

This chapter is about the methodology for Skin Type Detection. Methodology

is very important in develop any system or application because it is a step to show the

more organize ay we can develop or system or project. There are various types of

methodology development in developing an application system. Each of the chosen

approach has been refined to suit the project to be developed.

3.2 Methodology

Waterfall Methodology

Waterfall method is chosen because it organized and structured. Much like

construction and manufacturing workflows, waterfall methodology is a sequential

design process. This means that as each of the six stages (requirement analysis, design,

implementation, implementation, testing, and maintenance) are completed, then can

move on to the next step.

As this process is sequential, once a step has been completed, we can’t go back to a

previous step – not without scratching the whole project and starting from the

13

beginning. There’s no room for change or error, so a project outcome and an extensive

plan must be set in the beginning and then followed carefully.

Figure 3.1: Waterfall Model

Requirement analysis

Requirement analysis is the first phase in Waterfall Model which specific

requirement are analyse to understand the problems. The requirement is analyse

by doing a research on existing system and documentation. It also discusses on

functionality and the main process of the system. Literature review is done with

research information gathered by comparing technique, algorithm and method

used. In addition, objectives are figured out with the scope of the system.

14

System design

In design stage, the diagram of Context Diagram(CD), Data Flow

Diagram(DFD) and Entity Relationship Diagram(DFD) is built to more clarify

about the application. Next, database and interface is design based on the

process involve in the system.

Implementation

Implementation phase is beginning once the design is approved. This project is

developed using MySQL, DreamWeaver and XamppServer. XamppServer is

used as the localhost server. The system is developing by based on database and

interface designed in system design phase.

Testing

The application is tested after the implementation is completed. There are two

types of testing which is black-box testing and white-bow testing. Testing the

system is to find any error occur in the system to determine whether the

application meets specified requirement. The testing is repeated if there are any

errors.

Deployment

The application is deployed in the client environment or released into market and

reviewed whether the system meets all the goals in the project plan or not.

15

Maintenance

Maintenance process is the final phase of the Waterfall Model, to measure the

effectiveness of the system and evaluate potential enhancements. The purposed

of this stage is to improve the program. The maintenance lets monitor the

implementation of a program based on feedback, and understand and why

something happen. Next, assess program efforts by determine how well it

meeting the objectives and provide lessons learned for future programming.

3.3 System Requirements

The important in a development of the system is the system requirements. They are

software and the hardware that will be used to build up the entire system. Thus, Skin

Type Detection will be used several hardware and software when developing this

project.

CHAPTER IV

CONCLUSION

Through the website Skin Type Detection, that will be developed, I hope I can build it

with the objectives is being fulfil. Besides, I hope this website can really help user in

finding their truly skin type and the product that really suitable with their type. Besides

it can help the user to take care of their skin when they know their skin type and know

how to take care of it before start using the wrong product and wrong way. Finally, I

hope I can build this website successfully with just low limitation of works.
