Skin Pigmentation: Unmasking the difference between hyperpigmentation, melasma, hypopigmentation, and post-inflammatory hyperpigmentation.

Subtle changes in the appearance of our skin can have a significant impact on how we perceive ourselves. And, despite our best efforts at maintaining our self-confidence, it's disturbing when the first patches of blotchy pigment appear on our face, neck, or chest.

Prioritising broad-spectrum sun protection will be your first line of defence to reduce or delay the development of uneven skin pigmentation, along with understanding the different types of hyperpigmentation and the causes, will help determine the most effective skincare solutions to suit your needs.

The Genesis of Skin Pigmentation.

The origin of skin pigmentation concerns lies in the disruption of melanogenesis – the intricate cellular process that produces pigment within the skin and sets the stage for skin conditions like melasma, hyperpigmentation, hypopigmentation, and post-inflammatory hyperpigmentation, each with a unique impact on our skin's appearance and health.

When your skin is functioning normally and exposed to the sun, melanogenesis triggers the production of pigment that results in a tan. This tan helps to thicken and protect it from further sun damage. Unfortunately, excessive sun exposure, ageing, and hormonal imbalances can cause cellular activity to go awry, leading to unwanted patches of blotchy pigment and uneven skin tone.

In this article, we'll look at the different types of skin pigmentation, the causes and the best skin treatments to improve your skin's health and overall skin tone.

Skin Pigmentation

Hyperpigmentation: Blotchy Patches of Pigment

Hyperpigmentation is a broad term to describe the various forms of pigmentation that can appear on the skin. These variations in skin tone are frequently linked to sun and heat exposure and may take years to become noticeable on the skin's surface.

Over prolonged periods, excessive exposure to sunlight without proper UV broad-spectrum sun protection can trigger sun damage and lead to hyperpigmentation.

The extent of uneven pigmentation emerging on your skin's surface is influenced by factors such as your geo-location, genetics, exposure to the sun and the consistency of your sun protection practices.

An uneven skin tone can manifest as sunspots, age spots, freckles, and solar lentigines. These can take the form of flat, circular patches (age spots), small, slightly darker spots (freckles), or larger, irregular spots (solar lentigines) and are often associated with sun exposure.

Melasma: Unmasking the Mask.

Melasma is commonly the result of hormonal disruptions, ranging from pregnancy, hormonal imbalances, and the use of hormonal birth control.

Melasma is often characterised by its distinctive mask-like appearance, typically manifesting on the face, and is further exacerbated by heat, whether from the sun or heated environments.

If you're familiar with this form of hyperpigmentation, you're well aware of its challenges.

Although broad-spectrum sun protection is essential, it's only one piece of the puzzle. To effectively manage melasma, it's crucial to avoid solutions involving heat-related devices, such as laser technology, as heat acts as a trigger and can exacerbate melasma.

Instead, consider seeking advice from a trusted Aesthetic Rx skin care professional regarding the use of chemical peels and adopting an effective Aesthetic Rx skincare routine.

Post-Inflammatory Hyperpigmentation (PIH): The Aftermath of Skin Trauma.

Post-Inflammatory Hyperpigmentation (PIH) frequently arises following skin trauma, such as the aftermath of acne, where scarred skin becomes pigmented when inadvertently exposed to the sun.

It can also develop after treatments like chemical peels, microdermabrasion, or laser procedures when the skin is particularly vulnerable, and without proper sun protection, post-inflammatory hyperpigmentation can occur.

When the skin undergoes inflammation caused by trauma or injury, it produces more melanin, the pigment responsible for skin colour. This excess melanin can accumulate in certain areas, leading to dark patches or spots.

PIH is a temporary skin condition that usually responds well to skin care solutions and generally fades over time. Individuals with darker skin tones are more prone due to heightened melanin response to inflammation.

Hypopigmentation: The Lighter Side of Uneven Skintone.

Hypopigmentation is the opposite of hyperpigmentation. It refers to areas of the skin that are lighter or have less colour than the surrounding skin.

This condition arises from reduced melanin production, and several factors can contribute to hypopigmentation:

Vitiligo is perhaps the most recognisable cause, where the immune system attacks and destroys melanocytes (pigment-producing cells), resulting in white patches of depigmented skin.

Hypopigmentation can also result from skin injury or trauma, similar to the process seen in post-inflammatory hyperpigmentation. In this instance, instead of activating pigment, the skin develops white patches that can be permanent.

Skincare Solutions for hyperpigmentation. 

When dealing with various types of hyperpigmentation, several effective skincare ingredients can help improve skin tone and reduce the appearance of dark patches of pigment.

Here are some of the best skincare ingredients for treating hyperpigmentation:

1. Vitamin C (Ascorbic Acid):

  • Tyrosinase is the enzyme that stimulates pigment. When your melanin cells become dysfunctional, vitamin C becomes a vital ingredient to minimise the output of this enzyme.
  • Aesthetic Rx Vitamin C Serum 23% reduces inflammation, inhibits tyrosinase and minimises the effect of heat on your skin, making it an excellent skincare ingredient for treating all types of hyperpigmentation, including melasma.
2. Alpha Hydroxy Acids & Beta Hydroxy Acids (AHAs & BHAs):
  • Lactic and Citric Acids (AHAs) help to exfoliate the top layer of skin, improving tone and texture for brighter skin.
  • Salicylic Acid (BHA) accelerates surface exfoliation to lift away dead skin cells and brightens skin tone.
  • Aesthetic Rx Ultimate Serum combines the power of lactic, citric, and salicylic acids with other brightening skincare ingredients to reduce the appearance of hyperpigmentation. 
3. Retinoids (Vitamin A):
  • Retinoids, derived from vitamin A, promote cell turnover and inhibit melanin production to combat hyperpigmentation and sun damage.
  • Start with a nightly application of a low-strength retinol formula such as Aesthetic Rx Retinol Vitamin A serum. As your skin becomes accustomed to retinoids, you can advance to higher concentrations such as Aesthetic Rx Vitamin A Serum 1% Retinol and then Total DNA Repair, which contains retinal, the ultimate vitamin A super-power and ideal for the successful treatment for all types of hyperpigmentation.
  • For the best results, seek the advice of an Aesthetic Rx skincare professional before commencing your retinoid journey.
4. Niacinamide (Vitamin B3):
  • Niacinamide (vitamin B3) helps regulate melanin production while improving overall skin texture, protecting the skin from solar heat, reducing inflammation and decreasing the transfer of pigment to the outer cells of your skin, where it becomes visible.
  • Aesthetic Rx Ultimate Serum combines niacinamide (vitamin B3) with exfoliating ingredients and botanical extracts to power up your results and reduce unwanted hyperpigmentation.
5. Brightening Botanical extracts:
  • White Mulberry, Hibiscus, and Cucumber Extracts are botanical extracts that collectively enhance skin health while addressing concerns such as lightening pigment.
  • White mulberry extract: Parts of this plant, including the leaf and root, have been shown to brighten and improve the look of uneven skin tone when used in combination with other proven skin-brightening ingredients. The vast antioxidant properties in this extract help even out skin tone, lighten age spots and fight blemishes.
  • Hibiscus extracts: Hibiscus is rich in antioxidants that help reverse the pigment damage caused by UV rays, particularly in combination with the organic acids in this plant extract (Pyruvic & Citric acids), which help in the shedding of dead skin cells, just like an exfoliant.
  • Aesthetic Rx Ultimate Serum combines all three botanical extracts in a potent antioxidant formulation to reduce hyperpigmentation and protect the skin from future sun damage.
