Skincare products, such as serums, moisturizers, and eye creams, are staples in nearly all skincare routines. However, your diet and lifestyle choices play a significant role in the health and appearance of your skin.

When selecting and purchasing supplements, from vitamin C and probiotics to fish oil and marine collagen supplements, it is crucial to thoroughly assess the company and product to ensure they are safe for consumption. Supplements are not approved by the FDA before hitting the market, so selecting a trusted and accredited brand will ensure you consume safe and high-quality products.

Collagen

Collagen supplements are arguably one of the most popular supplements marketed to individuals seeking healthier and more radiant skin. Researchers are still studying the impact of collagen supplements on the skin, but evidence suggests that they can aid in improving specific aspects of skin health, such as elasticity, hydration, and wrinkle depth. 

However, scientists do warn that although collagen supplements have been shown to offer numerous health benefits affecting the skin, hair, and nails, media and retail marketing have exaggerated their actual impact. Therefore, it is essential to manage your expectations when incorporating collagen supplements into your daily routine. 

Probiotics

Probiotics are booming in the health and lifestyle industries, and their benefits don’t just affect the gut. When dysbiosis, a hormonal imbalance, occurs in the gut, the body is more likely to develop inflammation, increasing the risk of triggering additional skin conditions. Additionally, bacterial imbalances in the gut can impact other bodily collections of bacteria, such as the skin microbiome. 

However, achieving gut hormone balance is more than just taking a probiotic every day. Your diet, general lifestyle, sleep schedule, and stress levels are just a handful of the many different factors that impact gut health, and in turn, your skin health. Furthermore, it is essential to note that probiotic supplements are not necessary or appropriate for everyone, so it is crucial to consult with your doctor before starting any new supplemental regimen. 

Vitamin C

Vitamin C is a vital component for collagen production and helps to protect the skin against harmful UV rays. This is primarily why a vitamin C deficiency often leads to issues with collagen formation, impaired wound healing, and other negative impacts on the skin. Most people opt to use topical vitamin C treatments to improve the appearance of their skin, but some evidence suggests that supplementing with the vitamin can lead to increased collagen production and enhanced skin appearance when taken in conjunction with other nutrients, such as zinc and collagen. 

Furthermore, vitamin C supplements are generally safe to use and may offer additional benefits related to cognitive function, cardiovascular health, and the immune system. They are also a good supplement for anyone who gets less-than-adequate amounts of vitamin C through their diet.

Fish Oil ( Omega-3 Fatty Acids)

Multiple studies have shown the numerous health benefits of omega-3 fatty acids, including improved heart health and reduced joint pain. However, they also play a vital role in skin function, and failing to meet sufficient levels can negatively affect your skin and potentially lead to skin diseases. 

Research suggests that omega-3 supplements can benefit anyone with skin conditions like acne, psoriasis, skin ulcers, and atopic dermatitis, and may also help protect against skin cancers. However, there is little evidence to suggest that it improves the actual appearance of the skin outside of helping to clear acne. 

Vitamin E

Vitamin E has been found to offer noticeable improvements to the appearance of skin, particularly when it comes to fighting external aggressors. Similar to vitamin C, vitamin E is an antioxidant that could help mitigate damage caused by free radicals from sun exposure and pollution. 

This damage can impact DNA, the skin, cells, and connective tissue, potentially leading to more serious health concerns and complications. Vitamin E can play a protective role for the skin, but it is crucial not to take too much, as it can cause problems with blood clotting. 

Multinutrients

Some studies suggest that incorporating supplements containing a balanced blend of minerals, vitamins, and other ingredients may aid in improving common skin conditions, such as dullness and dry skin. A 2019 study that followed 50 women taking multinutrient supplements over the span of 12 weeks experienced significant improvements in skin pigment, dryness, dullness, and overall appearance when compared to a placebo group. 

Multivitamins can improve the health and appearance of individuals who suffer from deficiencies in specific nutrients, such as Vitamin C, Vitamin A, certain B vitamins, and zinc. If you suspect you may benefit from taking a multivitamin for your skin, it is best to consult with your doctor to establish what is best for you.

Biotin

Biotin is a B vitamin and a key ingredient in many skin, hair, and nail supplements. Although many people swear by using biotin for healthy and glowing skin and strong hair, there is no concrete evidence to support claims that it benefits hair, nails, or skin – unless you suffer from a biotin deficiency, which is rare. 

For most people who maintain a balanced diet, many foods, such as eggs and oats, naturally contain biotin, and common gut bacteria also produce it. Additionally, biotin supplements may interfere with certain laboratory tests, such as thyroid function tests, which could be hazardous in emergency situations. Unless recommended by your healthcare provider, it is best to skip biotin supplements entirely.
