Types Of Hyperpigmentation(Hyperpigmentation झाइयों के प्रकार): Part 2| ClearSkin, Pune | (In HINDI)


Hello. I am Dr. Dhananjay Chavan, Cosmetic Dermatologist
and Hair Transplant surgeon, Clear Skin and Hair MD,
Pune. Welcome back to the 2 nd part of the hyperpigmentation
video. If you have not watched part 1, do watch it. The link is in the video
description. In this video, we will discuss the different
types and causes of hyperpigmentation .
The first type of hyperpigmentation which is very common in Indian skin is
called photo hyperpigmentation or photo tanning. As we know, when our skin gets exposed to
the sun, the melanin production increases. This results in our skin getting tanned. Melanin pigment absorbs the sun’s rays and
block them to some extent. It
also helps to avoid or reduce the side effects caused due to overexposure
to the sun. When our skin gets exposed to the sun’s
UVB rays they cause photo damage to our skin. Cause the skin to peel off and cause photoaging. Those people that spend a lot of time in the
sun and work outdoors have very tanned face, hands, feet and necks. This happens because these are
the areas exposed to the sun. When you spend a lot of time in the sun, you
may even have sunburns as the skin’s epidermal cells absorb UVA and
UVB rays of the sun. In fact, these ultraviolet rays are very strong
and harmful between 10 am and 4pm. If you are outside at this time, your skin
will naturally protect itself by increasing melanin production. This will result in tanning or
hyperpigmentation. In some cases, the UVA rays may cause the
redistribution of the pre- existing melanin in the skin. The melanin gets oxidized and your skin may
get temporarily tanned for a few hours or days. Exposure to UVA and UVB rays results in an
increase in melanin production that causes delayed tanning. The next type is post inflammatory hyperpigmentation. Post inflammatory hyperpigmentation or PIH
can happen on the skin because of any inflammatory injury on the
skin. When there is any kind of injury on your skin,
your skin starts the natural healing process. During this process the melanin production
increases at the injury site or the existing melanin gets redistributed. PIH is very common in the Indian skin type. PIH affects the topmost layer
as well the lower layer of the skin. PIH happens after injuries, but it also happens
in certain skin conditions like seborrheic dermatitis, tinea versicolor and
surma. In fact PIH commonly occurs after acne, acne
excoriee and after poking and prodding pimples, and is especially visible
on dark skin. The next type is maturational dyschromia. Maturational dyschromia is a condition in
which hyperpigmentation is visible on the forehead and cheeks. This type of hyperpigmentation may
occur due to years of sun exposure. This condition is often misdiagnosed
as melasma or facial PIH. This can be treated using sunscreen, skin-
lightening agents, antioxidants, microdermabrasion, or chemical peels. The next is periorbital hyperpigmentation. Periorbital hyperpigmentation is medically
known by several names, but it is commonly known as under-eye dark circles. Dark circles have many different causes that
may be internal or external. Often the internal reasons are genetic. Familial pigmentation around the
eyes, excessive vascularity or superficial vasculature, large veins, sunken
veins, vitamin K deficiency, facial structure, sudden loss of fat, thin skin,
infraorbital swelling, dermal melanocytosis, skin diseases like atopic
dermatitis, vitamin deficiencies, premature ageing, and wrinkles can all
cause under eye dark circles. External factors like excessive sun exposure,
airborne or contact allergies, fatigue, excessive strain on the eyes, PIH,
hormonal pills, and improper nutrition can also cause under eye dark circles. Dark circles are caused by the lower eyelids
getting pigmented red or due to discoloration by bluish veins. The lower eyelid may also have brown-
black hyperpigmentation and the muscles around the eyes may droop or
sag. Dark circles is mainly a lifestyle condition
that can be treated by improving your lifestyle. But skin-lightening creams and chemical peels
can be used to treat them as well. In extreme cases, reliable medical treatments
like fractional erbium Yag laser, Fractional CO2
laser, Q-switched Nd YAG laser, autologous fat transplantation, fat
grafting, blepharoplasties, dermaroller, PRP, and fillers may be used. The next type is Riehl melanosis. In Riehl melanosis or pigmented contact dermatitis,
brown-grey colored dermal melanin deposits are visible on the
skin. This pigmentation is caused due to a change
in the usage of cosmetics. In this type of pigmentation, you may experience
redness or an unusual scratching sensation. It is important to avoid allergens to treat
this type of pigmentation. Sun protection, skin lightening creams and
chemical peels may be used to treat Riehl melanosis. The next pigmentation type is melasma. This is quite common, especially in
skin type 4, that is our Indian or Asian skin type. Melasma is generally seen on the cheeks, nose,
forehead, upper lip and mandibular area. Indian skin is more prone to melasma, It is
seen more commonly in women. The common causes of melasma are unprotected
sun exposure, overexposure to the sun, oral contraceptives,
stress and hormonal fluctuations. Melasma is also called the mask of pregnancy
because this condition is caused due to the hormonal fluctuations seen
during pregnancy. Melasma appears as symmetric, blotchy, light
to dark brown patches on the central forehead and cheeks. If the pigmentation is visible below the jaw
line, it is not melasma. Melasma has different types that are based
on the location of the melanin. When the melasma is epidermal, the pigment
is brown. This is light
pigmentation or marginal pigmentation. In dermal melasma, the pigment is deeper,
in the dermal layer. It appears
grey brown and this type is poorly defined. In the mixed type, the melanin is seen in
both the dermis and epidermis. The epidermal type is quite superficial and
is comparatively easy to treat. A combination approach is used to treat melasma. Topical skin lightening
agents, chemical peels, laser therapy and most importantly, strict sun
protection is necessary. Topical medications and broad – spectrum sunscreen
is recommended for the first line of treatment. The second line of treatment includes chemical
peels and laser light therapies. If the melasma is caused due to oral contraceptives,
they should stop taking the medicine. Melasma can be treated, but the main problem
in this condition is that it is recurring. That is why maintenance and strict sun protection
is required to prevent recurrence. You should apply broad spectrum sunscreen
with SPF 30 and PA protection before stepping out and reapply
it every 2 or 3 hours. You should also protect yourself with a scarf,
cap, sun coat, gloves and umbrella. The next type is exogenous ochronosis. In this type of hyperpigmentation, there is
a deposit of homogentistic acid in the dermis. This deposit is caused by any foreign substance. This results in
macular or papular hyperpigmentation. Pigmentation occurs on the face, sides, back
and neck. This pigmentation is caused by the use of
hydroquinone, resorcinol, phenol, mercury or picric acid. In ochronosis, the skin gets pigmented in
blue-black shades. It is very difficult to treat ochronosis. In some cases, dermabrasion,
fractional erbium YAG, mild fractional CO2 laser, glycolic acid peels and Q-
switched Nd YAG laser give good results. The next pigmentation type is Acanthosis nigricans. In this pigmentation dark, velvety patches
appear in the body folds and creases. Commonly this condition presents itself on
the forehead, axilla, between the arms, around the neck or posterior neck
and on the face. Along with darkening, the skin thickens also. Acanthosis nigricans is caused due to insulin
resistance, hormonal disturbances and obesity. Unfortunately, there is no treatment that
will cure it completely. Any therapy tries to treat the underlying
disease process. Weight reduction,
dietary correction, avoidance of high glycemic foods, sweets, fast food,
exercising and lifestyle changes are an important part of treating
Acanthosis nigricans. In some cases, topical medications like topical
tretinoin, triple-combination, depigmenting cream, sunscreen, and salicylic
acid is effective. The next type is dermatosis papulosa nigrosa
or DPN and seborrheic keratoses. The cause of DPN is unknown. DPN appears as raised pigmented papules of
around 5millimeters, on the forehead, cheeks, neck, chest and back. DPN can happen early and there are higher
chances of having it if there is a familial tendency. This is the main difference when compared
to seborrheic keratoses, otherwise both the
skin conditions are quite similar. DPN may appear in the teenage years and may
increase with age and time. Sometimes these lesions can be itchy. Treatment is generally done for cosmetic purposes. It is necessary to take proper care of your
skin to avoid dyspigmentation. Some of the treatment modalities are snip
excision, curettage, electrodesiccation, light cryotherapy , and
laser destruction. The next is nevus of Ota. This is a type of birthmark that is visible
on the face and is more commonly seen in people with dark skin. This pigmentation is bluish-grey. These lesions are seen during infancy till
the age of 11. The overall appearance is quite irregular
and the size is a few centimetres. Nevus of Ota can be successfully treated. Q-switched ruby, alexandrite, and Nd:YAG lasers
are very effective treatment modalities. Now advanced picoseconds lasers are also available. You will get better and faster results if
pigment reducing lasers are combined with fractional CO2 lasers. So these were the different types of pigmentation. Certain pigmentation types can be medically
treated to get good results but treatments may not be as effective for other
types. A lot of our patients ask us why exfoliating
or scrubbing does not help with hyperpigmentation. Our epithelial cells are formed in the basal
cell layers and as they mature and keratinise they keep coming to the upper
layers of the skin. They get fully keratinised and die and form
a wall of thousands of dead skin cells on the skin’s surface. They protect the DNA of the live skin cells
and then get exfoliated slowly. This is a normal phenomenon. But sometimes this melanin does not go to
the upper layers and settles in the basal or border layers. This may happen due to injuries, excess sun
exposure, trauma to the basal cell layer, autoimmune disease, breakage of
the dermo-epidermal junction, or inflammation. These melanocytes come to
the dermal layer and start producing melanin pigment. This melanin
pigment gets stuck in the dermis and does not get exfoliated. This leads to
dermal pigmentation. That is why your dermatologists keep telling
you that pigmentation may occur till the lower dermal layers. It can get quite difficult to treat this and
you may have to try several different treatments. To get long term results, it is necessary
to use topical medicated creams and medical procedures like light lasers to
treat pigmentation. Now we will discuss the treatment modalities
for hyperpigmentation in the next video, part 3. I hope that you will watch the next video
as well. The link to the video is
given in the description below. Thank you.
