Common Causes of Uneven Skin Tone

Uneven skin tone tends to develop slowly, with factors contributing to discolouration over time. The most common causes include:

Sun Exposure

Ultraviolet (UV) radiation can damage multiple layers of your skin. To protect itself, the skin produces extra melanin. This overproduction of melanin can result in dark spots.

Breakouts

The stress from a breakout can trigger excess melanin production or damage blood vessels, leading to post-blemish marks. These red, brown or purple marks stay behind on the skin after a blemish has healed. There are two types of post-blemish marks.

Post-Inflammatory Erythema (PIE): Blemish-related inflammation can damage the tiny blood vessels in your skin. PIE results when those damaged blood vessels remain visible, even after a blemish is gone. PIE is more common in lighter skin tones.

Post-Inflammatory Hyperpigmentation (PIH): Sometimes the skin reacts to stress (like blemishes) by making too much melanin. PIH results when extra melanin concentrates in one place and creates a dark brown or purplish spot. PIH is more common in melanated skin.

Environmental Stressors

Pollution, harsh weather, and UV exposure can damage the skin and trigger excess melanin production. This may contribute to dark spots, dullness, and uneven skin tone.

Aging

The skin’s renewal processes naturally slow with age, making our skin more susceptible to sun damage and discolouration.


Ingredients That Target Skin Discolouration

The look of hyperpigmentation, such as dark spots, uneven skin tone, and post-blemish marks can be addressed with several different ingredients.

Alpha Arbutin: A naturally derived brightening agent known for targeting uneven skin tone at its source. With regular use, alpha-arbutin can help fade dark spots and support more even, radiant-looking skin.

Niacinamide: A form of vitamin B3 that helps intercept discolouration before it becomes fully visible. Consistent use of niacinamide supports a brighter, more even-looking complexion.

Glycolic acid: An alpha-hydroxy acid (AHA) that gently exfoliates the surface of the skin to visibly brighten and even tone. Its small molecule size allows it to penetrate skin quickly and effectively.

Broad-spectrum SPF: A daily sunscreen helps protect your skin from damaging UV exposure, which can worsen existing sun damage and lead to new discolouration.


An Effective Regimen For Uneven Skin Tone

A complementary approach can be the most effective way to improve the look of discolouration. Here’s how to layer multiple targeted formulations in your AM and PM routines.



Supporting a More Even-Looking Complexion

A consistent skincare regimen with targeted ingredients can help improve the appearance of dark spots and uneven skin tone. When it comes to discolouration, visible changes take time. The more diligent you are with your routine, the more likely you are to see results.

Remember that using a daily broad-spectrum SPF does just as much to support even-looking skin as targeted formulations. By shielding your skin from UV radiation, you help prevent existing discolouration from becoming more apparent and guard against further damage.

Maintaining your skin barrier with hydrating, supportive products can also contribute to overall skin clarity. The skin barrier helps protect the skin from environmental stressors that can lead to the look of hyperpigmentation and irritation-induced redness.
