Introduction 

The best way to maintain healthy skin - youthful, clear, radiant, supple, soft, and wrinkle-free - is to protect yourself from the sun. The sun's ultraviolet (UV) rays give skin a healthy tan, but damage the skin with pigmentation, sunburn, and loss of elasticity. These causes can lead to premature aging in the form of wrinkles, fine lines, sagging, dark skin, uneven skin tone, loss of opacity, enlarged pores, and dryness. Even genetic best practices, topical skin lightening treatments, and oral transdermal supplements won't help if they're taken consistently and consistently. 

 Protecting yourself from the sun is helpful, but if you can't avoid it, you need to make sure you use sunscreen. This is especially important if exposed to the sun for long periods. 

 Assuming we are already sensitive to sun exposure, how can we further improve the condition of our skin? We know that some oral supplements are effective for good skin health, but what are these supplements, and how do they work? 

 Interior supplements 

 The first group will be vitamins and minerals, which are necessary for the normal functioning of each organ. 

 Vitamins and minerals that can affect skin health include the B-complex, especially B1, B2 (riboflavin), and B12 (cyanocobalamin). An excessive deficiency of vitamins B1 and B2 is known to cause particular forms of dermatitis (a type of inflammation of the skin). B12 deficiency is particularly detrimental to rapidly dividing cells and nerve cells, including skin cells. 

 Besides the B vitamins, deficiencies in vitamin C, iron, and copper also affect skin health. All three are important for the synthesis of collagen, an important structural protein in the skin that helps plump and gives skin firmness. 

 Vitamin A is required for the normal life cycle of skin cells.  A deficiency in vitamin A makes the skin dry, fragile, and prone to wrinkles. On the other hand, taking too much vitamin A can lead to serious poisoning and should be avoided. 

 Vitamins C, E, and beta-carotene are considered antioxidants that reduce free radicals. (Free radicals lead to skin degeneration and aging.) However, while free radicals and the role of antioxidants is beyond doubt, clinical results have yet to prove whether supplementing vitamins and other micronutrients improve skin quality and challenge the aging process.

Overdose can be as harmful as a deficiency, so it's best to stick to the recommended daily intake criteria (RDA). 

 Topical Supplements 

 Oral supplements should accompany the topical application –  at least SPF 30 sunscreen, cream (preferably with a whitening agent), and moisturizer (preferably with a whitening agent). Oral supplements are slower and more subtle than topical applications. Consumers need to be realistic with their expectations, as results are certainly not seen in 7 days or 2 weeks. 

•  A holistic approach to skin health is recommended. It consists of: 
• A healthy and balanced diet containing all food groups, vitamins, minerals, and micronutrients. 
• Keep you happy and positive. It is well known that some skin conditions, such as acne and eczema, are common in stressed people. 
•  If you smoke, please quit smoking. Smoke causes free radicals, damages the circulation of blood inside the skin, and also causes stains on the teeth and other discolorations. 
•  Minimize exposure to sunlight and use good sunscreen daily.
