Garlic, well-known for its many health benefits, has also gained fame for its potential to stimulate skin lightening.
This modest ingredient, packed with antiviral, anti-inflammatory, and antibacterial properties, holds promise in improving complexion. Also, the antioxidants found in garlic aid in fighting oxidative stress, safeguarding the skin from sun damage and rejuvenating its appearance.
Yes, garlic can be a good agent for skin lightening because of its antioxidant and antimicrobial activities, which contribute to removing acne, dark spots, and overall skin spots.
Furthermore, garlic has potential in managing conditions such as xeroderma pigmentosum, which is characterized by redness, scaliness, freckles, and irregular dark spots on sun-exposed areas such as the face. (1)(2)
This article will explore the science behind why and how garlic can be used for skin lightening.
The Science Behind Garlic for Skin Lightening
Garlic contains a compound called alliin, which is converted to allicin when crushed or chopped. Allicin acts as a strong antioxidant, and it can protect the skin from oxidative damage induced by dangerous molecules called free radicals or reactive oxidative species (ROS). (3)
These ROS can cause hyperpigmentation (skin darkening); thus, herbal remedies with antioxidant properties such as garlic are useful for achieving brighter skin.
By decreasing the levels of ROS in the melanocytes (melanin-producing cells), garlic may help prevent the process responsible for darkening the skin, revealing its potential in skin brightening. (4)
Furthermore, exposure to sunlight can darken the skin and can lead to long-term tanning by altering melanin distribution. Research suggests that garlic offers protection against sunlight-induced skin damage, which also contributes to premature aging. (1)(5)(6)
How to Use Garlic for Skin Lightening
Here are some simple steps on how to use garlic for skin lightening.
Note: Always do a patch test before applying garlic to the face. Do not use it if you experience a burning sensation or itching.
Using garlic topically for skin lightening
- Crush or mince a few cloves of fresh garlic and mix it with a carrier oil such as olive oil or coconut oil.
- Apply the garlic and oil mixture to the skin and massage it gently for a few minutes.
- Leave the mixture on the skin for 10–15 minutes.
- Rinse the skin thoroughly with lukewarm water.
- Repeat the process 2–3 times a week for best results.
Another way to use garlic for skin lightening is to mix garlic juice with lemon juice and apply it to the face. Lemon juice contains vitamin C, which is a potent antioxidant that can help to lighten the skin. (7)
Using garlic orally for skin lightening
- Extract the juice from garlic cloves by mashing them and straining the juice.
- Dilute the garlic juice with water or combine it with a beverage you like to make it taste more enjoyable.
- Drink this mix every day to experience its potential skin-lightening effects.
You can also consume raw garlic cloves regularly by simply swallowing them.
How Long Does It Take for Garlic to Lighten the Skin?
The time it takes for garlic to lighten the skin may vary depending on the individual and the method of use. It may take several weeks to see visible results.
Other Skin Benefits of Using Garlic
Garlic, known for its pungent aroma and culinary uses, has also been found to offer benefits for various skin conditions.
1. Psoriasis relief
Garlic can help with psoriasis relief. Research suggests that garlic can interfere with the activation of a specific factor called nuclear transcription factor kappa B, which is linked to psoriasis, a chronic skin condition characterized by red, scaly patches. (1)(8)
2. Treating keloid scars and promoting wound healing
For keloid scars, garlic extract is believed to inhibit certain substances, such as nuclear transcription factor kappa B, nitric oxide, and matrix metalloproteinase, potentially serving as an effective treatment option. (9)
Moreover, garlic’s properties have been investigated for wound healing, where it may contribute to re-epithelialization (regrowing of the skin’s outer layer) and neovascularization (formation of new blood vessels). (10)
3. Healing cutaneous warts and antifungal action
Garlic has demonstrated antiviral effects, with one study reporting complete resolution of cutaneous warts after applying garlic extract.
Furthermore, garlic extract has shown promising results in treating fungal infections, inhibiting the growth of Candida albicans and providing a potential alternative to conventional antifungal drugs. (1)
4. Antiaging effects
Garlic has been found to have potential antiaging effects by supporting the ability of skin cells called fibroblasts to grow and multiply. This can help in maintaining the youthful appearance of the skin and facilitate its rejuvenation. (1)
Adverse Effects of Garlic Use
Potential negative effects associated with garlic use include skin conditions such as contact dermatitis, allergic reactions, zosteriform dermatitis, contact urticaria (hives caused by contact with a specific substance), and pemphigus (blistering of the skin and mucous membranes). (1)
So, be careful when using garlic for skin lightening or other reasons. If you experience negative reactions, avoid using it any further and talk with a professional.
Final Word
Garlic has been used for centuries as a natural remedy for various health issues, including skin problems.
While there is limited scientific research on the use of garlic for skin lightening, some experts suggest that garlic may be effective in improving skin texture and reducing the appearance of dark spots.
