Is it possible to decrease melanin production?
| 6 minutes
Achieving a brighter, more even skin tone often involves addressing the production of melanin, the pigment responsible for skin colour.
While melanin plays a crucial role in protecting your skin from sun damage, excess melanin production can lead to dark spots, uneven tone, and hyperpigmentation.
In this post, we will explore top skincare ingredients, simple dietary tips and natural vitamins and supplements that help minimise pigmentation and enhance your skin's natural glow.
What is melanin?
It is a pigment produced by our body that influences variations in skin tones, hair colours and eye shades. Melanin is produced by cells called melanocytes, located in the skin’s outer layer.
The amount and type of melanin you produce are largely determined by genetics, but factors like sun exposure, certain topical skincare ingredients and dietary preferences can highly influence melanin production.
How to reduce melanin in face: effective tips and treatments
To effectively reduce melanin in the skin, incorporating ingredient-based solutions along with a targeted skincare routine can help block the enzyme responsible and gradually lighten pigmentation.
To begin with, it is essential to target the process of melanin production at the cellular level.
This process, known as melanogenesis, involves the enzyme ‘tyrosinase’, which plays a crucial role in converting the amino acid tyrosine into melanin.
By inhibiting tyrosinase activity, you can effectively reduce melanin production, leading to a lighter skin tone over time.
1. Topical skin care ingredients that help reduce melanin in skin
When exploring how to reduce melanin in face, consider integrating both topical treatments featuring these key ingredients with the following tips -
Glycolic acid
It works by breaking down the bonds between dead skin cells on the surface, facilitating their removal.
This process, known as desquamation, is crucial in reducing hyperpigmentation as the outermost layer of skin often contains excess melanin.
By accelerating the shedding of pigmented cells, Glycolic Acid gradually reveals newer, less pigmented skin beneath, promoting a more even skin tone over time.
Niacinamide
This versatile ingredient is effective in reducing the transfer of melanin to the skin's surface.
By interfering with the process of melanin distribution, Niacinamide helps to even out skin tone and diminish hyperpigmentation, contributing to a more uniform complexion.
Vitamin C
As a potent antioxidant, Vitamin C not only helps to inhibit tyrosinase but also promotes collagen production.
This dual action reduces pigmentation and brightens the skin, and improves skin firmness.
Retinol
Known for its ability to enhance cell turnover, Retinol accelerates the shedding of pigmented skin cells and promotes the growth of fresh, lighter skin underneath.
This helps to reduce the appearance of dark spots and uneven pigmentation.
Kojic Acid
Derived from fungi, Kojic Acid is known for its skin-brightening properties. It inhibits tyrosinase, the enzyme responsible for melanin production, thereby reducing pigmentation and fading dark spots.
Kojic Acid is widely used in skin care products to treat conditions like hyperpigmentation and melasma.
Azelaic Acid
Found naturally in grains like barley and wheat, Azelaic Acid works to inhibit tyrosinase, reducing abnormal melanin production.
It is especially effective for treating hyperpigmentation and post-inflammatory pigmentation caused by acne or other skin conditions.
Alpha Arbutin
A naturally occurring derivative of hydroquinone, Alpha Arbutin works by inhibiting tyrosinase activity, which leads to a reduction in melanin synthesis.
It is considered a safer alternative to hydroquinone and is commonly used to treat dark spots, age spots, and overall uneven skin tone.
Licorice Extract
Known for its anti-inflammatory and brightening properties, Licorice contains glabridin, a compound that inhibits tyrosinase activity.
This helps reduce melanin production and soothes the skin, making it suitable for sensitive skin types.
2. Protect your skin from UV exposure
Excessive or repeated sun exposure can lead to uneven melanin distribution, resulting in hyperpigmentation issues such as dark spots, freckles or melasma.
This occurs because UV rays can trigger overproduction of melanin in certain areas.
Regular use of broad-spectrum sunscreen with SPF 50 helps prevent UV-induced melanin production, reducing the risk of blemishes and hyperpigmentation.
3. Exfoliation
In areas of hyperpigmentation, exfoliation helps with the removal of dead skin cells, which contain excess melanin concentration.
Exfoliants such as AHAs (alpha hydroxy acids) penetrate deep into the skin, interfering with melanin production and gradually reducing the appearance of dark spots.
4. Use hydrating and barrier-strengthening products
Incorporate moisturisers that contain Ceramides and humectants like glycerine or Hyaluronic Acid.
These ingredients help maintain a strong skin barrier and keep your skin hydrated, which can
reduce the appearance of pigmentation and support overall skin health.
Natural ways to reduce melanin: dietary and vitamin-rich solutions
When addressing how to reduce melanin naturally, consider integrating the following dietary and vitamin-rich elements that can naturally work towards reducing melanin levels and achieving a balanced skin tone.
1. Foods rich in antioxidants
Antioxidants play a crucial role in neutralising free radicals, which are unstable molecules that can damage skin cells and stimulate melanin production.
Key foods to consider:
- Citrus Fruits: Oranges, lemons, and grapefruits are rich in vitamin C, an antioxidant that helps reduce melanin and brighten the skin.
- Berries: Blueberries, strawberries, and raspberries are loaded with antioxidants that protect the skin from oxidative stress and reduce pigmentation.
- Nuts: Almonds and walnuts provide vitamin E, which supports skin health and inhibits melanin production.
- Green Leafy Vegetables: Spinach, kale, and broccoli are packed with vitamins and antioxidants that limit melanin stimulation and improve skin health.
- Lycopene-Rich Foods: Lycopene is a natural antioxidant found in certain fruits and vegetables that can help reduce melanin naturally and protect the skin from UV damage.
Foods high in lycopene include:
-
Tomatoes: Tomatoes and tomato-based products are excellent sources of lycopene.
- Watermelon: This refreshing fruit is another great source of lycopene, which helps minimise melanin concentration and protects the skin from environmental stressors.
-
Soy Products: Soy contains isoflavones, plant compounds that can help reduce melanin production and improve skin tone. Adding soy products to your diet, such as tofu, soy milk and edamame, minimise melanin pigment transfer promoting skin lightening and a more even complexion.
2. Reduce melanin naturally with vitamins and supplements
Vitamins and supplements offer a range of benefits from neutralising free radicals to inhibiting enzymes involved in melanin synthesis.
For a natural approach to how to reduce melanin in skin, focus on incorporating specific vitamins and supplements into your routine that help lighten pigmentation and enhance skin tone.
Listed below are essential nutrients and how they help to reduce melanin naturally -
Glutathione
It is a powerful antioxidant that plays a role in inhibiting melanin synthesis. Glutathione shifts the production of melanin from darker eumelanin to lighter pheomelanin, resulting in a lighter skin tone.
Glutathione also reduces oxidative stress by neutralising free radicals, which can otherwise stimulate increased melanin production as a protective response. It helps impart a lighter skin tone and improved complexion.
Zinc PCA
It helps in balancing melanin levels by acting as a cofactor for enzymes involved in DNA repair and skin regeneration, which is vital for maintaining healthy skin.
It also supports wound healing and promotes cell turnover, aiding the skin in shedding damaged, pigmented cells.
Vitamin E
Vitamin E protects the skin from oxidative stress caused by free radicals. This protection helps to prevent an increase in melanin production.
Vitamin E supplements and topical products can help maintain healthy, evenly-toned skin by reducing the impact of environmental stressors.

Mineral vs Chemical Sunscreen - The Right One For Your Skin
Applying sunscreen regularly is one of the simplest—and the most effective—ways to maintain your skin’s health and appearance. No matter what age you are—you can always benefit from sunscreen. It prevents sunburn, reduces the risk of skin cancer, prevents premature ageing, reduces hyperpigmentation, etc. You can say even sunscreen is the main character of your skincare routine. But, have you ever wondered what type of sunscreen is right for your skin? There are two types of sunscreens available—chemical and mineral sunscreen. When discussing these two types of sunscreens, questions such as "Which one is more effective?" or "Which one stays longer on skin and offers better UV protection?" are bound to come up. Well, this blog answers all the questions. Let’s get the low down on everything you need to know about mineral vs chemical sunscreen. View this post on Instagram A post shared by Re'equil (@reequil) What is mineral sunscreen? Mineral sunscreen, commonly referred to as inorganic or physical sunscreen, works by reflecting or scattering UV rays—they contain active ingredients that are metal oxides—such as zinc oxide or titanium dioxide. When you apply mineral sunscreen on your body or face, they basically work as sheets of metal and oxygen—or you can say they are opaque in nature (not see-through). Thus, it makes sense that mineral sunscreen doesn’t absorb into your skin—it rather sits on top of your skin. Moreover, mineral sunscreens are better for individuals with sensitive skin, acne, or skin conditions like eczema. Such sunscreens are usually non-irritating and do not cause any adverse effects. The 2019 FDA report says that zinc oxide and titanium dioxide are GRASE (generally recognized as safe and effective) for use in sunscreens. A 2019 study says that due to the reflective properties, mineral sunscreens are also called sunblocks, a term less used nowadays for sunscreen. However, there is one challenge that many face with any mineral sunscreen—that it may leave behind an excessive shine or a white cast—which usually limits the cosmetic acceptance of mineral sunscreens. What is chemical sunscreen? Chemical sunscreen forms a protective shield on your skin to absorb UV rays. When applied, its ingredients penetrate the epidermal layer. Upon contact with UV rays, chemical sunscreen converts the rays into harmless heat via a chemical reaction, preventing them from reaching the epidermal layer. The heat is then released from your skin. This conversion is crucial because you don't want UV rays to reach the epidermal layer of your skin, where your melanin is. If melanin absorbs UV rays, it can cause serious damage like hyperpigmentation and accelerate the skin ageing process. Chemical sunscreens generally have the following ingredients - Oxybenzone Octinoxate Octisalate Avobenzone Chemical sunscreens are also cosmetically accepted as they blend easily with makeup and don’t usually leave a white cast. They absorb instantly and don’t make your face look greasy or shiny. However, some people are hesitant to use chemical sunscreen because the ingredients in it can cause an adverse reaction—especially if the sunscreen comes in contact with the eyes. Moreover, the FDA report does not classify the chemical sunscreen ingredients as GRASE (generally recognized as safe and effective). What are the key differences between a chemical and mineral sunscreen? Here’s a breakdown of the differences between a chemical and mineral sunscreen—knowing them can help you figure out which one is better for your skin type and concerns. Chemical sunscreens Mineral sunscreens Absorbs UV rays Reflects UV rays Contains carbon-based ingredients like oxybenzone, avobenzone, etc. Contains inorganic compounds like zinc oxide and titanium dioxide Thinner texture, spreads evenly and gets absorbed instantly Has a thicker texture, difficult to spread evenly on the face Takes about 20 minutes after application to provide protection from UV rays Provides immediate protection More transparent finish, leaves no white cast Opaque in nature, can leave an extra shine and white cast Can cause an allergic reaction to some individuals and clog the pores Considered safe for all skin types and recommended by dermatologist to individuals with sensitive, acne-prone skin Chemical vs mineral sunscreen: which one protects the skin from UV rays for longer? Both mineral and chemical sunscreens offer the same duration of sun protection. While it may seem that chemical sunscreens, because they penetrate the skin, offer longer-lasting UV protection than mineral sunscreens. But that is not the case—how long sunscreen stays on your skin depends on your activity throughout the day, such as if you are swimming or sweating—along with how much sunscreen you apply. Which one is more suitable for individuals with acne? Mineral sunscreen ingredients are typically more suitable for acne-prone and sensitive skin. Zinc oxide and titanium dioxide are among the safest sunscreen ingredients. They are gentle on the skin and do not cause adverse reactions. Additionally, mineral sunscreen ingredients are non-comedogenic, meaning they won't clog your pores. Zinc oxide, in particular, can help improve acne by fighting germs, and healing wounds, and acne lesions. It also contributes to sebum regulation, making mineral sunscreens an ideal choice for individuals with oily skin. Which one is better, chemical or mineral sunscreen? Many of the points discussed in this blog suggest that mineral sunscreen is superior to chemical sunscreen. However, it is all about your preference and skin type. If appearance is not your biggest concern and you are okay with a little white cast or extra shine on your face—you can go with the mineral sunscreen. It provides broad-spectrum protection and contains inorganic ingredients. On the other hand, if you are an individual who usually wears makeup, chemical sunscreen is a better option for you since it blends easily and does not leave behind any greasiness or white cast. In terms of sun protection, there really isn’t much difference between mineral and chemical sunscreen—both effectively protect your skin from UV rays. And if you can’t seem to choose between a mineral or chemical sunscreen—you can go ahead with a hybrid sunscreen—it contains both inorganic and organic ingredients.
