What is Melatonin?
Melatonin is a hormone naturally produced by your body. Its main job is to regulate your sleep-wake cycle, essentially telling you when it’s time to sleep.[1] Your brain releases melatonin in response to darkness, making you feel tired and ready for rest at night.[2]
Beyond sleep, melatonin has other important roles in the body, including some related to your skin.[3] Recent research suggests that melatonin might have beneficial effects on skin health, our body’s largest organ.
The amount of melatonin your body produces changes throughout your life. Babies produce very little, while children and young adults make the most.[4] After young adulthood, melatonin levels tend to decrease, which may contribute to sleep problems in older people.[5]
Melatonin and Skin Health
Antioxidant Properties
Melatonin is a powerful antioxidant. It helps protect your cells from damage caused by unstable molecules called free radicals.[6] These molecules can damage cells and DNA, leading to signs of aging.
Your skin is constantly exposed to free radicals from the sun, pollution, and stress. Melatonin helps to neutralize these harmful molecules, preventing them from damaging your skin cells.[7]
Melatonin is a very effective antioxidant, surpassing vitamins C and E in fighting certain types of free radicals.[8] This makes melatonin a helpful protector of skin health.
UV Protection
Ultraviolet (UV) radiation from the sun is a major threat to skin health. It can cause sunburn, premature aging, and increase the risk of skin cancer.[9] Melatonin can offer some protection against this damage.
When your skin is exposed to UV light, it produces melatonin as a natural defense. This hormone absorbs UV radiation, preventing it from harming your skin cells.[10] It also stimulates other antioxidants that help protect the skin further.
While melatonin offers some protection from UV rays, it should not replace sunscreen. Sunscreen provides stronger, more reliable protection against sun damage.[11] Think of melatonin as an additional layer of defense, not a primary one.
Anti-Aging Effects
As skin ages, it can develop wrinkles, sag, and have an uneven tone. Melatonin may help address these changes through its various beneficial actions.[12]
Sign of Aging | Melatonin’s Effect |
---|---|
Wrinkles | Supports collagen production |
Sagging | Enhances skin elasticity |
Uneven Tone | Regulates pigment-producing cells |
Dryness | Improves skin barrier function |
Melatonin can help your skin repair and rejuvenate. It activates antioxidants and promotes the creation of another antioxidant called glutathione.[13] This protects your skin cells and DNA from damage.
Melatonin also influences how skin cells grow and renew. It stimulates the production of fibroblasts, which create collagen.[14] More collagen means firmer, more youthful-looking skin.
Melatonin Production in the Skin
Your skin doesn’t only rely on melatonin made in the brain. It can also produce its own supply. Skin cells have the necessary tools to create melatonin locally.[15]
Several factors affect how much melatonin skin produces:
- Age: Older skin generally makes less melatonin
- Sun exposure: UV light stimulates melatonin production
- Time of day: Skin melatonin levels are higher at night
- Stress: Can reduce melatonin synthesis in the skin
Environmental and lifestyle factors also influence skin melatonin:
- Pollution
- Diet
- Sleep patterns
- Skincare routine
Understanding these factors can help us support our skin’s natural melatonin production.
Topical vs. Oral Melatonin for Skin Health
Melatonin can benefit skin when applied directly or taken as a supplement. Each approach has its own advantages and disadvantages.[16]
Topical melatonin is applied directly to the skin, allowing you to target specific areas. It’s easy to add to your regular skincare routine.[17]
Oral melatonin supplements affect your whole body. They can improve overall skin health, but may also have effects beyond just your skin.[18]
Method | Pros | Cons |
---|---|---|
Topical | Direct application to skin | Limited systemic effects |
Can target specific areas | May not penetrate deeply | |
Easy to add to skincare routine | Effects limited to applied area | |
Oral | Affects whole body | May cause drowsiness |
Can improve overall skin health | Dosage can be tricky | |
May have additional health benefits | Potential for side effects |
How well each method works depends on the specific skin issue. Sometimes, using both topical and oral melatonin may be the most beneficial approach.[19]
Melatonin and Specific Skin Conditions
Eczema and Psoriasis
Melatonin is showing promise in managing skin conditions that involve inflammation. Its anti-inflammatory and antioxidant properties may help soothe irritated skin.[20]
In cases of eczema, melatonin might help reduce itching and improve sleep. Eczema often leads to poor sleep, which can worsen the condition.[21]
For psoriasis, melatonin’s ability to regulate cell growth may be helpful. Psoriasis causes rapid skin cell turnover, which melatonin might help to normalize.[22]
Research on using melatonin for these skin conditions is still new. More studies are needed to fully understand how well it works and how to use it best.[23]
Acne
Melatonin may also benefit people with acne-prone skin. Its anti-inflammatory properties could help reduce the redness and swelling associated with acne.[24]
Melatonin might also help regulate sebum production. Excess sebum contributes to acne, so balancing its production could lead to clearer skin.[25]
Additionally, melatonin’s antioxidant properties could help heal acne scars. By protecting skin cells and promoting repair, it may improve skin texture over time.[26]
Skin Cancer Prevention
Melatonin’s potential role in preventing skin cancer is an exciting area of research. Its ability to protect against UV damage is particularly relevant to this area.[27]
Studies suggest melatonin might help prevent skin cancer in several ways:
- Neutralizing free radicals caused by UV exposure
- Repairing UV-induced DNA damage
- Boosting the immune system’s ability to fight abnormal cells
While research is promising, further studies are needed. Melatonin should not be used instead of proven skin cancer prevention methods such as sunscreen and protective clothing.[28]
How to Use Melatonin for Skin Health
Incorporating melatonin into your skincare routine needs some thought. Whether using topical products or supplements, it’s important to use them safely.[29]
General guidelines for using melatonin for skin health:
- Start with a low dose, especially for supplements
- Apply topical melatonin at night for best results
- Be consistent – regular use may yield better outcomes
- Combine with other skincare ingredients for synergistic effects
- Monitor your skin’s response and adjust as needed
It’s always a good idea to talk to a healthcare provider before starting any new supplement. They can help determine the best approach for your individual needs.[30]
Potential Side Effects and Precautions
While generally considered safe, melatonin can cause side effects in some people. Some common issues may include:
- Drowsiness
- Headaches
- Dizziness
- Nausea
When using melatonin topically, some individuals might experience skin irritation or allergic reactions. Always test new products on a small area of skin before applying them to your face.[31]
