Natural Home Remedies for Hyperpigmentation

Introduction

A variety of human skin colours are evident across the globe, ranging from the very pale to very dark skin complexion. There are several conditions related to skin pigmentation over this spectrum of skin tones, resulting in problems ranging from hypopigmentation (patches of skin that are lighter than your actual skin tone) to hyperpigmentation (patches of skin that are darker in colour than the surrounding skin)¹.

Skin hyperpigmentation occurs when melanin, a pigment that is responsible for imparting colour to the skin, is overproduced in certain areas of the skin. It is important to have a complete understanding of the causes of this condition and the management strategies³.

What Causes Hyperpigmentation

Hyperpigmentation can be caused by several factors like:

1. Exogenous Factors

These have an external cause or origin and include:

• Sun damage (these spots are also known as solar lentigines)
• Post-inflammatory hyperpigmentation (due to injury to the skin like acne, cuts, or burns)³

2. Endogenous Factors

These have an internal source or origin and include: 

• Adrenal disorders like Addison’s disease: A condition where the body produces insufficient cortisol
• Genetics (like freckles)
• Hormonal changes during pregnancy or puberty
• Medications like oral contraceptives and photosensitising drugs
• Thyroid disorders
• Diabetes
• Acanthosis nigricans: A skin condition that results in dark pigmentation in body folds and creases
• Acromegaly: A hormonal disorder due to the excess secretion of pituitary hormone
• Carcinoid: A slow-growing cancer that arises in many places in the body
• Nelson syndrome: A disorder marked by abnormal hormonal production, pituitary gland enlargement, and development of massive and invasive growths called adenomas
• Cushing’s syndrome: A condition where the production of cortisol increases too much over time
• Pheochromocytoma: A non-cancerous tumour that grows in the adrenal gland

3. Nutritional Factors

Deficiencies of certain vitamins like folic acid, vitamin B12, niacin, vitamin A, tryptophan deficiency, and kwashiorkor (a type of malnutrition due to protein deficiency in the diet) may contribute to hyperpigmentation³.

Studies⁴ conducted on animals have shown that the use of aloe vera leaf extract, specifically its active compound ‘aloin’, can lead to skin lightening by restricting melanin formation. As a result, aloe vera gel may be employed to alleviate skin hyperpigmentation.

Symptoms of Hyperpigmentation

Different types of hyperpigmentation and their symptoms include:

• Hyperpigmentation due to Sun Damage: These are small, darkened patches that are commonly observed on the hands, face, and other sun-exposed areas.
• Melasma: These appear similar to age spots but are larger areas of darkened skin that occur due to hormonal changes.
• Freckles: Freckles are small, brown spots that can develop anywhere in the body. These spots are, however, common on the face and arms. Freckles, age spots, and other dark skin patches can get darker when exposed to the sun⁵.

Suggested Home Remedies for Hyperpigmentation

Home remedies for hyperpigmentation may help improve the appearance of dark skin patches. Some remedies include:

1. Aloe Vera Gel

The gel of this plant is used to manage many skin conditions. It may be useful to reduce hyperpigmentation of the skin. Aloesin is the active ingredient of aloe vera and can potentially control an excess of melanin production and skin hyperpigmentation⁶. To obtain beneficial effects, you can apply aloe vera gel directly to the affected area. You can also put aloe vera gel in your homemade face masks.

2. Green Tea

It is known for its antioxidant and anti-inflammatory activities. Green tea has potential skin-lightening effects and may help lighten hyperpigmentation. In one study⁶, green tea was also found to be effective in preventing skin redness caused by ultraviolet (UV) radiation. To use green tea for skin, you can make a green tea face mask or put green tea in your homemade mask recipes.  

3. Soy

This remedy is an effective skin-lightening agent. Soybean is helpful in post-inflammatory hyperpigmentation due to acne. It is also effective in photodamage (changes in the appearance of skin due to UV radiation), facial hypermelanosis (altered facial skin pigmentation), and melasma⁶. You can add soy to your diet to get the much-needed benefits. Sipping on soy milk is a good option.

4. Rice Water

This is one of the essential ingredients in several Asian skin and hair treatments. The gel and cream formulations of rice water exhibit skin lightening effect. Rice water may be a helpful remedy for dealing with hyperpigmentation⁶. There are several ways through which you can make use of rice water.

• You can massage rice water onto your skin and rinse it with water.
• You can also make a face mask by soaking a thick sheet of tissue paper in rice water and using it as a sheet mask.
• You can put a small amount of rice water on a cotton pad and apply it gently on the face and neck like a toner.

5. Turmeric

This home remedy may also be beneficial in managing hyperpigmentation⁷. To use turmeric for skin, you can make a turmeric face mask. To make the facemask, you can mix small amounts of turmeric, honey, and Greek yoghurt and apply it to your face. You can keep the mask for 15 minutes and then wash it off with water.

6. Pomegranate

Rich in antioxidants, pomegranate may help reduce pigmentation². To use pomegranate, you can crush a few seeds and use it as an exfoliating mask. Make sure to massage gently as it might irritate the skin. You can also use pomegranate skin oil. You should apply the oil only after cleansing and toning but before moisturising.

7. Grape Seed Oil

The oil obtained from grape seeds is rich in vitamin E and C, potent antioxidants. The antioxidant benefits are useful for dealing with hyperpigmentation⁸. To use grape seed oil, you can:

• Apply pure grape seed oil as a serum on your face before going to bed.
• Mix a few drops of seed oil in your moisturiser or cream to get the benefits.
• Mix grape seed oil with some other essential oil, like lavender. You should use not more than a few drops of essential oil with grape seed oil.

Research⁴ has demonstrated that soy contains fatty acids and isoflavones that hinder melanin production (a pigment responsible for skin colour). Soy-based skincare products are proven safe and effective in reducing hyperpigmentation, with noticeable skin lightening results typically seen after 12 weeks of twice-daily use. Prolonged daily use over 7 months does not lead to adverse effects and the depigmentation effects are reversible. You may therefore use soy-based products to reduce hyperpigmentation.

When to Seek Medical Help

You should consult your dermatologist (skin and hair specialist doctor) when you notice symptoms like:

• Red skin
• Itchy skin
• Painful skin
• Skin that is hot when touched
• Bleeding or pus discharge from the area of hyperpigmentation.

Conclusion

At times, extra melanin is produced by the skin, resulting in dark spots or patches that contrast with the surrounding skin. Hyperpigmentation is a common skin condition that can, however, make one self-conscious. The causes of hyperpigmentation can be external and internal. Some of the home remedies that can be used to manage hyperpigmentation include aloe vera gel, green tea, soy, rice water, turmeric and pomegranate. However, you must visit a doctor if you notice red, itchy, or painful skin, skin that feels hot on touching, or bleeding or pus discharge from the hyperpigmented skin.
