Today Nida Esth' Medical Centre has gathered knowledge about the problem of melasma, freckles and dark spots and clearly point out the difference so that everyone can choose the right treatment and care for yourself. So, if you are ready, let's get started...

1.Get to know the differences between blemishes, freckles and dark spots


'Melasma', 'freckles' and 'dark spots' are problems for many women, especially Asian women who are constantly exposed to sunlight which causes melanin pigments on the face. But, nowadays, many of us still have some confusion between melasma, freckles and dark spots because, visually, these three facial skin problems share some similarities.



Therefore, if we want to treat melasma, freckles, and dark spots and see obvious results. First of all, we have to get to know the different problems of melasma, freckles and dark spots in order to choose and plan the most suitable treatment for our problems.

Melasma can be divided into 4 types

  • Mild melasma looks like brown with clear edges. It is easily caused by the production of melanin pigment that is higher than usual at the epidermis level. It can be cured by applying a melasma cream and using sunscreen regularly.
  • Deep melasma is gray-brown, bluish-gray, and purple-colored and it is caused by the production of melanin pigment more than usual at the dermis level. Therefore, it is more difficult to treat than mild melasma. Also, treatment with melasma or the use of sunscreen will only help slightly improve the problem but it will not completely be gone.
  • Melasma caused by sunlight is initially a dark brown, black or red color caused by exposure to UV rays from sunlight, house lights, computer light and phone light. If it does not taken care of properly, the color will become increasingly darker.
  • Blood melasma looks like broken capillaries on the face.  This type of melasma occurs from the use of non-standard creams or cosmetics such as steroids, mercury, etc., making the skin thin and more sensitive than usual. It is necessary to see a doctor for treatment.



“Freckles” are divided into 4 types: 

  • Mild freckles look like small and light brown spots with clear boundaries; it is often found in areas exposed to sunlight, such as cheekbones or nose. It is also more common in teenagers and people with fair skin. This type of freckle is caused by malfunctioning pigment cells and therefore very sensitive to sunlight.
  • Deep freckles are small, dark brown, grayish-black spots with unclear boundaries. It has a blemish-like appearance, smooth skin, clustered all over a certain facial area. It usually occurs around the cheekbones and nose.  The main reason is the abnormality of pigment cells in the dermis which is stimulated by UV rays from sunlight, together with hormones that increase during adolescence or pregnancy.
  • Freckles caused by sunlight are light brown in color with clear boundaries; it is small in size and usually caused by sunlight and aging. It can be found in areas that are regularly exposed to sunlight, such as a face, arms, and legs, which, if left unattended, can become larger and more severe. Unfortunately, it can not fade away naturally. 
  • Seborrheic Keratosis freckles look like tumors of the skin which is caused by the epidermis that has grown abnormally. It is light brown to dark and black and has blister-like appearance.  It is usually found on the face, neck, arms and body. It is caused by genetics, sunlight and increasing age.


“Dark Spots” are caused by skin inflammation such as acnes.


Dark spots are caused by inflammation under the skin which is the mechanism that occurs during acne. When the body enters the process of healing the skin in that area, it produces a large amount of melanin pigment which makes the area of acne that has healed becomes darker.  Most acne scars will fade on their own but it can take weeks or months. In addition, the more we are exposed to UV rays, the darker and longer acne marks from acne will be.

Causes of melasma, freckles and dark spots

It is obvious that freckles and melasma are clearly different; melasma is blotchy and larger in size, while freckles are small round spots with clear edges caused by heredity so if your parents have this sort of problem, you are likely to have them too. Also, those with white skin tend to have freckles more than dark skinned people.

The main cause of melasma, freckles and dark spots is UV radiation because when our skin receives a large amount of UV radiation, the melanin pigment on our face will be produced more.

In addition to UV rays, melasma can also be caused by stress, hormonal changes or insufficient rest, for example, some women in pregnancy may suddenly experience melasma as a result of hormonal changes within the body. Moreover, even some types of cosmetics and facial creams that contain perfume can also cause melasma too.

4. Update technology for "deep melasma, freckles and dark spots under the skin layer" of the year 2022 


PicoSure F.L.A. from USA

The superior difference of the Pico Sure Focus Lens Array in the treatment of melasma, freckles and dark spots.

Focus Lens Array evokes “Cell signaling” theory, which is at the heart of radiant youthful skin. No melasma-freckles-dark spots naturally along with technology developed from Cell - heal - Cell theory (cell repair cells) to create youthfulness without melasma - freckles. "PicoSure is a revolution in laser technology, with Picosecond Technology that has changed the way lasers work with high-frequency light waves with a speed of 1 per trillion seconds that destroys the abnormal pigment by vibrating violently (Photoacoustic) without causing heat (selective photothermolysis); therefore, there is no risk of burns and better results."

Pigment Flat Optic causes a phenomenon known as Pressure wave, which has enormous energy to break the black pigment that combines Melanin Pigment, which causes black patches of melasma, birthmarks and nevus (HORI's, Nevas of OTA). Therefore, it is easy for white blood cells (Macrophase) of the body to be eliminated, causing melasma - freckles to fade effectively in a short time compared to other technologies.

How does PicoSure FLA work?

It works by two mechanisms: Cell Signaling sends a youthful signal to rejuvenate the skin at the cellular level.  The skin is clear and youthful and decomposes excess melanin pigment into tiny particles. Therefore, the problem of freckles, such as dark spots that are difficult to treat, is therefore quickly eliminated. Another mechanism is the working principle of the Cell - heal - Cell theory to create a youthful appearance without freckles naturally.


5. What kind of sunscreen can actually prevent melasma, freckles and dark spots?

How much SPF sunscreen is appropriate?

Ultraviolet rays or (Ultraviolet: UV) types UVA and UVB are the main causes of melasma, freckles and dark spots. It also causes the generation of free radicals, wrinkled, sagging skin problems, sunburn, and skin cancer.

UVA rays can penetrate through glass into buildings. There's also blue light from cellphones and computer monitors, so even if you're indoors, please apply an appropriate amount of sunscreen.

Therefore, we should choose a sunscreen that has the ability to protect both UVA and UVB light, which can be observed from the SPF and PA, respectively, should choose an SPF level of 30 and PA 3+ or higher.

Do you wear sunscreen at home?

Did you know that even if we are in the house or indoors, it is not possible to avoid all sunlight and UV rays, especially UVA rays, which are long wave rays that are very powerful? It can penetrate into the building and this type of radiation is the one that can injure our skin deep into the dermis layer. If it hits our skin often, it will result in the destruction of collagen and elastin in the skin, causing wrinkles easily and a face to look older than actual age and it also increases the risk of skin cancer.  Therefore, it can be concluded that applying sunscreen, even at home, is necessary to do it on a daily basis.


6. How to prevent melasma-freckles-dark spots



  •  Avoid exposure to sunlight: Sunlight emits UV rays when exposed to intense UVA and UVB rays for a long time, it will cause free radicals in the body to increase until blemishes or freckles begin to show prominently in various parts of the face.
  • Try not to stare at a computer screen regularly: the light from the computer will cause heat to build up around your face. When it accumulates a lot, it reacts with the melanin pigment under the skin which can cause blemishes on the face.
  • Check for substances that may be allergic to cosmetics: such as perfumes, colors, preservatives or some cosmetics ingredients that can cause dark spots like freckles and blemishes. It is best not to change your makeup often because it can cause allergies easily or if you use any type of cosmetics and you have an allergic reaction. You should read the details of the ingredients in the cosmetics that there are any substances which contributes to the allergic reaction in order to avoid that substance when buying.
  • Avoid using non-standard creams: because fast-acting face creams are often full of mercury and various chemicals that hurt the skin, no origin, no clear ingredients. These creams, when used for a while, can cause blemishes. And worse than that, it can cause blemishes to be buried even deeper than before.
  • Consult your doctor before taking birth control pills: The pill contains sex hormones, making melanin cells to work more. Girls who take birth control pills have blemishes is easier to get freckles than people who don't take birth control pills, including those who are pregnant can have blemishes and freckles as well.
  • Get enough rest: In addition to causing wrinkles, acne and dull skin on the face, when the body is not resting enough, the body's internal systems are disrupted. It affects hormones in the body to not working well until causing stress that contains free radicals. As a result, melanin does not work well, causing blemishes to be appear more clearly.


7. Is it safe to undergo non-surgical facial reshaping procedures during Covid-19 in Bangkok, Thailand


During Covid-19, many of us living in Bangkok, Thailand, probably wonder if we can undergo facial procedures or not. The answer is that it can, of course, be done. But, we need to study the measures of a medical centre whether there are effective screening measures, for example, a Rapid Test Kit (ATK) is provided to clients as well as nurses, including doctors. Did the staff receive the full dose of vaccination?  In addition, the medical center should have standards and policies in patient care during the COVID-19 relief situation.

During a procedure, doctors and nurses should take preventive measures such as wearing masks, face shields and gloves to ensure that patients receive 100% safe service.


8. Scanning technology, analyze skin problems, and compare the results before - after; the only treatment that dares to guarantee



For the process of taking care of that facial shape, we can see the results before and after the procedure more clearly than just taking simple pictures. It starts from the first step which is very important. Imagine with the Clear Vision 2D&3D Camera to compare the results before and after the procedure to see clearly verifiable changes.

After selecting a clinic, we also need to study the information of doctors who are consulting and taking care of our treatment, whether they are specialists or not; a professional doctor should

  • Have clear diploma and professional certificates as we can check the list of surgeons at  https://www.thprs.org/find-doctor 
  • Have a lot of therapeutic works to be a guarantee of experience in his or her profession
  • Provide a technology that helps measure results before and after treatment to be concrete and abstract
  • Be able to provide a systematic treatment plan and ready to answer the problems of each patient
