The Newest Sun Safe Dark Spot Corrector? Meet Malassezin

Discover Malassezin – an effective, sun safe dark spot solution.

It can be frustrating when you’re struggling with dark spots from acne scars, sun damage or hormone fluctuations. Especially when many dark spot correctors can make your skin more vulnerable to sun damage, including ones with retinoids, vitamin C, and alpha hydroxy acids (AHAs). So, whether your go-to treatment is a serum or a spot treatment, you want to make sure you are using a sun safe dark spot corrector.

There isn't a single "number one" dark spot remover, since the best product for you depends on your unique skin type, the severity of your dark spots, and your personal skincare preferences. Many dark spot correctors work by increasing skin cell turnover and exfoliation. That can dry out your natural skin barrier, leading to redness and irritation. Malassezin works in a unique sun safe way to correct existing dark spots and prevent new spots from appearing.


Malassezin – The New Clinically-Validated Skincare Active for Dark Spots

Dark spot correctors are a specialized type of skincare that come in many forms. Some dark spot solutions need to be applied all over your face, others are spot treatments you only apply to affected areas. Some can only be applied at night while others are not recommended for sensitive skin. Finding the best dark spot corrector for your needs can be confusing and overwhelming. At Mother Science we like to keep things simple and effective, which is why Mother Science spent 6 years developing Malassezin, the newest sun safe dark spot corrector.

Unlike other dark spot correctors, Malassezin does not make your skin more sensitive to the sun. This gentle ingredient comes from the skin’s own microbiome (your skin’s natural protective layer of good bacteria) and so your body recognizes it. If you have sensitive skin, Malassezin is unlikely to cause any irritation, because it works with your skin’s natural protective layer. 

 

Here’s how Molecular Hero Serum works to reduce the appearance of dark spots:

1 - Malassezin prevents new dark spots by reducing excess melanin (pigment) at a cellular level.

2 - Malassezin is a powerful antioxidant (10x more powerful than vitamin C) that works to reduce the appearance of dark spots.

3 - Niacinamide moisturizes and soothes your skin, working with Malassezin to visibly reduce dark spots and even skin tone.


Regular use of antioxidants like Malassezin are known to reduce the appearance of wrinkles and dark spots. Related: how Malassezin beats vitamin C as a skin-brightening ingredient.

What Causes Dark Spots and Hyperpigmentation?

Those pesky dark spots and hyperpigmentation appear when your skin experiences some kind of irritation that causes it to overproduce melanin – the pigment responsible for your skin color. This excess melanin results in dark spots or patches that stand out against the surrounding skin.


Here are the main causes of dark spots and hyperpigmentation:

▪️ Prolonged exposure to ultraviolet (UV) radiation from the sun stimulates your melanin-producing cells (melanocytes) to become more active. 

▪️Hormonal changes from pregnancy or birth control can boost melanin production, leading to conditions like melasma. 

▪️Damage to your skin can trigger post-inflammatory hyperpigmentation when your skin overproduces melanin as part of the healing process.

▪️Genetic factors and aging can contribute to uneven melanin distribution and pigmentation issues. 


Overall, hyperpigmentation occurs as a side effect of your skin trying to protect itself.  By addressing the root causes of hyperpigmentation and supporting your skin’s natural protective barrier, Molecular Hero Serum offers a clinically-proven non-irritating approach to achieving a more even and radiant complexion.

Molecular Hero Serum – Dark Spot Corrector Powered by Malassezin

Many dark spot correctors are a class of actives known as tyrosinase inhibitors. These work by inhibiting your skin’s production of the tyrosinase enzyme – tyrosinase is the main enzyme recognized as responsible for melanin overproduction. Molecular Hero Serum contains sun safe Malassezin as its main dark spot correcting active, so it works in a completely different way.


Molecular Hero Serum offers unique benefits as a dark spot corrector:

✔️ Molecular Hero Serum works faster than many other dark spot correctors. In clinical testing, 100% of participants had a reduction in dark spots starting in 4 weeks. 

✔️ Molecular Hero Serum is sun safe and so can be used twice a day, and doesn’t cause photosensitivity or skin irritation.

✔️ Molecular Hero Serum supports your skin’s moisture barrier to improve the plumpness of your skin and helping it hold onto more moisture.


Molecular Hero Serum works well with other skincare actives so it’s easy to introduce into your skincare routine, even if you have sensitive skin. 

 


How to Incorporate Malassezin Into Your Skincare Routine

When you have so many great skincare actives available, it can be difficult to figure out how to add a new product into your skincare routine. The good news is that Malassezin plays so well with others that it’s easy to add Molecular Hero Serum to your skincare routine as the first layer. 

 

When you introduce Malasezin into your skincare routine, you may find you can actually reduce some of the products on your bathroom shelf, such as vitamin C. Malassezin is more shelf stable than vitamin C and 10x more powerful an antioxidant.
