Abstract: Background: Cheiloscopy is a forensic investigation technique that deals with identification of humans based
on lips traces. Several studies had been conducted to determine the distribution of different lip print pattern
in some clinical condition with genetic influence, such as hypertention and the inheritance of cleft lip and
palate. Melasma is one of skin disease which is also genetically affected. This study was aimed to find out
cheiloscopy and its pattern in patients with melasma compared with control. Methods: The study compared
lip print pattern between 30 individuals with melasma and 30 healthy controls. Lip prints were collected using
cellophane tape and recorded in white chart paper. All four quadrant of lip were observed. Results: Type IV
of lip prints dominated all four quadrants in individuals with melasma. From healthy controls, type I was
predominant in three quadrants of lip. Conclusion: The result from the present study indicates a significant
association between lip print pattern and melasma. Therefore, it may be possible to predict risks of developing
melasma in each person with significant association from lip prints.
1 INTRODUCTION
Melasma is a common hypermelanosis that typically
occurs on sun-exposed are in the face. The
appearance of pigment is heightened in the summer
when UV exposure is more common. At least three
clinical patterns have been described: centrofacial
(64%), malar (27%), and mandibular (9%). The
course is typically chronic, fading when UV exposure
is diminished (Lepeere et al, 2012). Onset of melasma
typically occurs in a woman’s childbearing years (20s
through 30s) and in darker skin types, such as
Hispanics, Latinos, Asians, and African-Americans
(Lee, 2014).
Melasma is a common hypermelanosis that
typically occurs on sun-exposed areas in the face. The
pathogenesis is poorly understood, but genetic and
hormonal influences in combination with UV
radiation are important (Lepeere et al, 2012; Lee,
2014). Racial and/or familial predisposition suggests
that genetic factors contribute to the pathogenesis of
melasma. Pigmentary disorders including melasma
are common in Hispanic and Asian racial groups with
Fitzpatrick skin types III/V, although a few
epidemiologic reports are available in different ethnic
groups. Studies from different countries address the
familial occurrence of the disorder. An epidemiologic
study in a tertiary dermatological referral center in
Singapore showed that a positive family history was
observed in 21 (10.2%) of 205 patients with melasma.
A study with 312 patients with melasma in India
reported that 104 patients (33.3%) had a positive
family history. Positive family history, as high as
54.7%, was shown in a study on 400 pregnant women
in Iran. Familial occurrence is as high as 56.3% of 302
patients from Brazil. Although the rate of occurrence
from different countries and even from the same
country shows a wide range of differences, family
history is associated with melasma on epidemiologic
study. However, to date, there is no study about
cheiloscopy in melasma.
Cheiloscopy (quiloscopy) can be defined as a
method of identification of a person based on
characteristic arrangement of lines appearing on the
red part of lips or as a science dealing with lines
appearing on the red part of lips. It is unique to an
individual, except for monozygotic twins. Lip groove
patterns can be identified from the 6th week of
intrauterine life (Peter et al, 2016).

Fischer in 1902 was the first anthropologist to
describe the furrows on the red part of the human lips.
However, it was only in 1932 that Edmond Locard,
one of Franceís greatest criminologists,
recommended the use of lip prints in personal
identification and criminalization. In 1950, Synder
reported in his book Homicide Investigation that the
characteristics of the lips formed by lip grooves are as
individually distinctive as the ridge characteristics of
fingerprints. Suzuki and Tsuchihashi, in 1970,
devised a classification method of lip prints, which is
as follows (Peter et al, 2016; Singh et al, 2017; Mishra
et al, 2009; Prabhu et al, 2012):
1. Type I : a clear-cut groove running vertically
across the lip.
2. Type I’ : partial-length groove of type I
3. Type II : a branched groove
4. Type III: an intersected groove
5. Type IV: a reticular groove
6. Type V : irregular/other pattern
Lip prints are unique and do not change during the
life of a person. It has been verified that lip prints
recover after undergoing alterations like minor
trauma, inflammation
and diseases like herpes. The
form of the furrows does not vary with environmental
factors (Gondivkar et al , 2009). Study shows that lip
print pattern does not change even as age advances.
Besides, cheiloscopy is easier to perform, very
helpful due to its unique pattern and often more
helpful in criminal investigations when other
identification methods or parameters are either not
available or difficult to analyze (Nagrale et al, 2014).
Several studies had been conducted to determine
the distribution of different lip print pattern in some
clinical condition with genetic influence, such as
hypertention and the inheritance of cleft lip and
palate. Melasma is one of skin diseases which is also
genetically affected. This study was carried out to
identify the peculiar lip patterns in patients with
melasma, weather it could be act as predictor for
individuals to get melasma later. As the final goals, it
might be use as preventive methods for melasma as
early as possible.
2 METHODS
A study sample comprised 30 females with melasma
and 30 females without melasma. All samples were
aged between 20 and 55 years. Lips were free from
any pathology, having normal transition zone
between the mucosa and skin were included in the
study. Consent of all the samples was obtained for the
study.
In order to classify the lip prints in this study, the
classification scheme proposed by Suzuki and
Tsuchihashi was used. Materials used were:
1. Red or brown colored lipstick
2. Cellophane tape and scissors
3. White chart paper
4. Magnifying lens
First, lips were cleaned thoroughly. Individuals with
hypersensitivity to lipsticks were not included in the
study. A lipstick was applied with single stroke,
evenly on the vermilion border. The subjects were
asked to rub both lips to spread the applied lipstick.
After two minutes, over the lipstick, the glued portion
of cellophane tape strip was placed and the subject
was asked to make lip impression in normal rest
position of the lips by dabbing it in the center first and
then pressing it uniformly toward the corners of the
lips. The cellophane strip was then stuck to a white
chart paper and then analyzed by using magnifying
lens. The lips were divided into four quadrants; two
quadrants on each lip, and were numbered from Q1-
Q4 in a clock-wise sequence starting from upper
right.
3 RESULTS
The lip print patterns were studied in 30 samples that
clinically diagnosed with melasma, compared with 30
healthy controls. Ethical approval was obtained and
all participants were explained about the purpose of
the study and also the informed consent was obtained
from each of the participant. The study of lip print
pattern of 60 samples including cases and controls
revealed the following observations on Figure 1 and
2.
4 DISCUSSION
Lip prints are very useful in forensic investigation and
personal identification. They are considered to be
most important forms of transfer evidence, and are
analogous to finger prints (Sharma et al, 2009; Telagi
et al, 2011).
In the present study, it was noticed that no two
individuals or more have similar types of lip prints.
Table 1 shows the distribution of lip print patterns
between individuals with melasma and healthy
controls. It revealed that each quadrant (Q) of lips had
a tendency towards a certain type. In 30 healthy
controls, type III was found in 11 (36.67%) samples
in Q1, type I as much 10 (33.33%), 13 (43.33%) also
13 (43.33%) in Q2, Q3 and Q4 respectively.

Type I, vertical groove pattern, have a higher
quantity in healthy controls. Vahanwalla and Parekh
(India, 2000) studied lip prints from 50 male and 50
female subjects from Mumbai and found that type I
(branched) was predominant in the lower lip among
the females (Umana et al, 2014).
Otherwise, type IV of lip prints dominated all four
quadrants in individuals with melasma. From the
study of lip prints, 19 (63.33%) samples of type IV
were found in Q1, 17 (56.67%) in Q2, whereas 13
(43.33%) samples in Q3 and Q4. The difference
pattern between cases and healthy controls is
significant. In other words, the research shows a
higher frequency of reticular groove type in melisma
(51.67%) than in healthy control (16.67%). From
literature there has been no research on lip print
pattern of melasma that could be comparison. To our
knowledge, this study is the first study of lip print
pattern in melasma.
5 CONCLUSION
During the past decade, numerous studies addressed
the uniqueness of lip groove patterns and it was
proved that it could be used for personal
identification. The tremendous research done in this
field itself proves its worth as a unique entity (Peter
et al, 2016). Research of lip print patterns in clinical
condition with genetic influence
The result from the present study indicates a
significant association between lip print pattern and
melasma. Therefore, it may be possible to predict
risks of developing melasma in each person with
significant association from lip prints. It can therefore
serve as a non-invasive predictive tool in determining
those people who are at risk of developing melasma
so that clinicians and the general public at large can
be informed and habits that could trigger melasma
can be avoided.
Despite the fact that identification of an individual by
lip prints appears to be accepted in some places, this
procedure requires further studies with larger sample
size. The uniqueness of lip prints pattern in melasma
needs to be more confirmed and accepted.
