Melanin protects skin from the sun's ultraviolet rays. These can burn the skin and reduce its elasticity, leading to premature aging. People tan because sunlight causes the skin to produce more melanin and darken. The tan fades when new cells move to the surface and the tanned cells are sloughed off.
When your skin is exposed to ultraviolet (UV) rays from the sun, it triggers melanocytes (the cells responsible for producing melanin) to produce more melanin as a protective response. This increased melanin gives the skin a darker appearance, often referred to as a tan.
To get a tan, you should sunbathe with sunscreen suitable for your skin type, eat a diet that is rich in beta-carotenes and moisturize your skin on a daily basis. This care should be started before sunbathing and maintained throughout the time you are exposed to the sun.
One cause of food-induced skin pigmentation is the chemical psoralen, which increases the risk of age spots and makes the skin more sensitive to UV rays. Psoralen is found in foods like the common fig, parsley, parsnips, limes, and celery.
Is My True Skin the Skin Tone I Get in the Sun? No. In fact, the color of your skin in the sun is a shade with much more melanin, caused by damage from ultraviolet rays.
Numerous variables, such as sun exposure, hormone changes, post-inflammatory hyperpigmentation, ageing, skin conditions, and lifestyle choices, can cause skin darkening. Understanding the underlying reasons will help us avoid or cure darker skin tones.
According to a study called “Shades of beauty,” light brown skin tones are often the most physically attractive skin color (Frisby et al., 2006). They used four models for that study. They did not change the skin tone, but they imaged each model to three different skin tones: light, medium, and dark.
The hyperpigmentation related to vitamin B12 deficiency is more common in darker-skinned patients. Few other cases of skin hyperpigmentation due to vitamin B12 deficiency have been reported in the literature. The mechanism of hyperpigmentation is due to increased melanin synthesis rather than a defect in melanin.
The incidence of this change varies, and depends on the type of medication involved. Some of the most common drugs involved are NSAIDs, antimalarials, psychotropic drugs, Amiodarone, cytotoxic drugs, tetracyclines, and heavy metals such as silver and gold (which must be ingested, not just worn).
Sun damage can lead to dark spots that can be lightened by topical skin-bleaching creams. Products with the ingredient hydroquinone are the most popular and effective. Hydroquinone 2% is available over the counter, but higher strengths of hydroquinone are available by prescription.
Genetic evidence also supports this notion, demonstrating that around 1.2 million years ago there was a strong evolutionary pressure which acted on the development of dark skin pigmentation in early members of the genus Homo. The effect of sunlight on folic acid levels has been crucial in the development of dark skin.
Eat foods rich in antioxidants
Diet is key to healthy skin and an ally for boosting your tan. There are a number of foods you can eat to complement your skincare and sun protection routine: Antioxidants: blueberries, aubergines and avocado are rich in vitamin C and zinc and can help you get the colour you want.
Conclusion: Darker skin pigmentation is associated with lower serum 25(OH)D concentrations. Serum vitamin D level also appears to be related to intake of vitamin D rich foods and multivitamins containing vitamin D, but not self-reported level of sun exposure or use of sun protection.
The deficiency of vitamin B12 can cause specific skin manifestations, such as hyperpigmentation, vitiligo, angular stomatitis, and hair and nail changes [1].
Addison's disease: It causes patches of dark skin around skin folds or joints. Diabetes rash: If you have diabetes, you may develop discolored skin patches or spots. Medications: Some medications can cause your skin to lighten or darken. Cancer: Certain cancers or paraneoplastic syndromes can cause pigmentary changes.
Natural Ways To Increase Melanin
Antioxidants may help protect melanocytes by fighting oxidative stress such as from UV rays, boosting pigmentation and bringing back your skin's color. Examples of extracts and antioxidants used to treat vitiligo include: Vitamins A, D, and E. Coenzyme Q10.
We found that green is the most popular lens colour, with brown coming in a close second, despite it being one of the most common eye colours. Although blue and hazel are seen as the most attractive eye colours for men and women they are surprisingly the least popular.
Natalie Portman is known for her perfectly clear and radiant complexion, her skin seems to glow so naturally. The star insists on the importance of drinking a lot of water every day to keep the skin moisturized and fresh.
Darker skinned people often look younger than their lighter skinned peers. Their skin appears smoother and tends to have less wrinkles even as they get older. Do we have the wrong impression or is there something really going on? It's true, darker skin ages slower than lighter skin.
