Skin pigmentation & dark spot are prevalent skin issues which can impact individuals of any skin tone. They can occur as a result of acne, sun damage, inflammation, hormonal shifts, and skin damage. Sometimes the marks fade by themselves and other sometimes it can last for months or even more years.

Pigmentation can appear more frequently in individuals who are exposed to the sun on a regular basis in Mexico, or even produce new dark patches. Over time, a basic regimen of mild skin care and sun protection should help to preserve skin and enhance skin color unevenness.

What’s important is being patient. Dark spots are naturally not cleared up in one day. Applying excessive quantities of powerful products can cause skin anger and discoloration to occur.

What Causes Skin Pigmentation & Dark Spot?

what causes skin pigmentation

Skin pigmentation is skin colour, which is mainly due to a pigment called melanin. Specialized cells known as melanocytes make melanin.

If the cells make increased amounts of melanin in some places, the skin may look darker. This darkening of the color is called hyperpigmentation.

Pigmentation may be affected by any of the following:

  • Sun exposure
  • Hormonal changes
  • Acne and inflammation
  • Skin injuries
  • Certain medications
  • Genetics
  • Some skin conditions

Not all pigmentation is a problem. It’s perfectly normal to have natural color differences in skin.

If it occurs rapidly or suddenly or if the pigmentation changes markedly, however, then it’s worth noticing the change.

What Causes Dark Spots?

There are a number of reasons for dark spots. Post-inflammatory hyperpigmentation (PIH) is one of the most common ones that can occur after acne, cuts, burns, insect bites or inflammation.

Another significant cause is exposure to sunlight. UV radiation can make existing sallowness look darker and accentuate it.

Hormones change may also be responsible for pigmentation. For instance, melasma may lead to dark, brown or gray-brown areas, particularly in the upper lip, nose, forehead and cheeks.

Common causes include:

CauseHow It May Appear
AcneDark marks left after pimples heal
Sun exposureFreckles, sunspots, or increased discoloration
Hormonal changesLarger patches of pigmentation
Skin injuryDark mark following inflammation or damage
Certain medicationsIncreased sensitivity or pigmentation in some people

Any dark spot that appears abnormal or changes in size, shape or color should be investigated by a health care provider.

Skin Care Routine for Dark Spots

Many products are not the best approach; the simple approach is often the better one.

Morning

Gentler cleansers (optional) → Treatment serum → Moisturizer → Sunscreen

Night

Cleanser, pigmenting treatment, moisturizing treatment.

Depending on your skin and the type of discoloration, you can use vitamin C, niacinamide, azelaic acid or any other suitable ingredient.

Avoid combining multiple active ingredients. Try one product at a time to determine skin reaction.

Most importantly, apply and reapply sunscreen regularly. If you don’t take care of your skin, you may not see much benefit from treatment for darkened areas.

Skin Care for Uneven Skin Tone

Uneven skin tone may result in patches of your face appearing darker or redder than others. This could be due to sun damage, acne scars, dehydration, skin irritation or other factors.

Taking a step back, the basics:

  • Do use a mild cleaner.
  • Moisturize regularly.
  • Avoid aggressive scrubbing.
  • Apply sunscreen daily in the morning.
  • If necessary, use a single targeted treatment.
  • Allow product to do its job.

Do not attempt to lighten your skin that much. The aim of proper skin care is to help the skin to maintain a uniform healthy appearance without altering the natural color of the skin.

If skin is irritated by a new product, reduce the product use until skin is not irritated.

Skin Care for Hyperpigmentation

It may take a while before hyper pigmentation improves. The first step is identifying and minimizing the trigger, when possible.

For instance, if dark marks are a problem due to acne, managing the acne will help keep pigmentation from developing.

It is particularly important to protect yourself from the sun if pigmentation is becoming a problem.

Some ingredients used as hyper pigmentation include:

  • Vitamin C
  • Niacinamide
  • Azelaic acid
  • Retinoids
  • Certain exfoliating acids

The right ingredient will depend on the nature of pigmentation and your skin tolerance.

Don’t use aggressive treatments without professional advice. Irritation can trigger further pigmentation especially in those with a predisposition to post-inflammatory hyperpigmentation.

Skin Care for Acne Marks

Acne will go away but may leave behind flat brown, red or dark marks. These are sometimes confused for scar marks.

A discolored area is not the same as a true acne scar, which will cause an alteration in the skin’s texture.

To care for acne marks:

  • Avoid getting more acne if possible.
  • Avoid picking or squeezing pimples.
  • Apply sun cream daily.
  • Think about using an appropriate brightening or pigmentation.
  • Do not allow skin to become dry.
  • Others may find it helpful to use ingredients like azelaic acid, niacinamide, vitamin C and retinoids.

Take your time, no hurry. Post acne marks fades over time, this process can take weeks or even months.

For deep acne scars, or if you have stubborn pigmentation, your dermatologist can suggest treatments for your skin and the type of scars you have.

Pigmentation and Dark Spots are caused by the ingredients listed below:

There are a few ingredients which are frequent in skin care products for dark spots and also uneven tone.

Ingredients for Pigmentation and Dark Spots

Several ingredients are commonly used in skin care products designed for uneven tone and dark spots.

IngredientCommon Skin Care Purpose
Vitamin CAntioxidant support and brighter-looking skin
NiacinamideHelps support the skin barrier and improve uneven tone
Azelaic acidCan help with acne and pigmentation
RetinoidsEncourage skin cell turnover and can help with several skin concerns
Glycolic acidExfoliation and improvement of uneven-looking skin
Salicylic acidHelps exfoliate and can be useful for acne-prone skin

Less is sometimes more. Combination of multiple effective ingredients may lead to dryness and irritation.

Use one product with a pigment and follow the directions if this is your first experience with pigmentation products.

Exfoliating acids and retinoids are particularly harmful for sensitive skin.

Sunscreen and Pigmentation

Sunscreen is one of the key modules in pigmentation management.

Suns exposure can activate melanin manufacture and emphasise existing dark spots. This is why you may not see as much results when you are not putting on a pigmentation serum while taking actions to protect your skin from the sun.

Use a broad-spectrum, high-SPF (30 or more) sunscreen and apply it liberally to exposed skin.

Re-apply as often as essential, particularly when outside, working hard, perspiring, swimming, and towel drying.

Many areas in Mexico are year-round sunbathers. Sun protection can be particularly crucial there.

Visible light can also cause some hyperpigmentation in individuals with a tendency to melasma or pigmentation. Tinted sun screen products with iron oxides can offer extra protection against visible light and can be a decent point to discuss with a dermatologist.

Keep in mind that sunscreen is most effective when used in conjunction with other sun protection measures such as shade, hats, clothes and other sun protection behaviours.

Some of the most frequent errors that people make with dark spots are listed below:

Common Mistakes When Treating Dark Spots

Common mistakes include:

  • Excessive scrubbing of dark spots
  • Be careful not to use more than one active ingredient.
  • Skipping sunscreen
  • Picking acne
  • Over-application of products with high levels
  • Expecting overnight results
  • The use of unproven skin lightening products.
  • Switching treatments every 2 to 3 days
  • Ignoring skin irritation

Stay away from products that claim to lighten the skin very quickly, or dramatically, but don’t give you a clear indication of what they contain.

There are some free skin-lightening products that contain harmful ingredients or secret ingredients.

If the treatment causes severe red-hot, swelling, redness, or discomfort, discontinue the use of the treatment and consult a health care provider.

The American Academy of Dermatology explains that sun protection is an important part of managing pigmentation such as melasma. Using sunscreen regularly and limiting sun exposure can help prevent discoloration from becoming darker.

When to See a Dermatologist for Pigmentation

While many dark spots are harmless, not all pigmented spots are appropriate for at-home treatment.

If any of the following apply, see a doctor for skin or hair care:

  • One spot all a sudden shifts.
  • A mole alters in shape, size or color.
  • A mark bleeds or repeatedly forms a crust.
  • Pigmentation occurs for no apparent reason.
  • There is ongoing spread of dark patches.
  • Products from drug stores, pharmacies, or health food stores do not help.
  • You have been losing your self-confidence due to pigmentation.
  • Not sure if the mark is acne related pigmentation, melasma or otherwise.

A dermatologist will be able to determine what type of pigmentation it is and then provide treatment. Treatment options for professionals may be prescription creams, chemical peels, laser treatments, or more, depending on the cause and skin type.

The best way to treat Skin Pigmentation & Dark Spot is to avoid any extreme DIY remedies and instead opt for slow and steady improvement techniques, consistent sun protection and gentle skin care. While many dark spots can’t be completely resolved, with a proper regimen and sensible expectations, they can grow less prominent the more time that passes.
