Youthful, smooth skin is highly desired in modern society,however, many do not seek out dietary changes to improve skin health.Many  research has been conducted on the role of nutrition and select nutrients and phytonutrients on skin health. Antioxidant and anti-inflammatory compounds play a role in blocking harmful UV rays or ensuring that their damage is minimized. Although topical creams and other products may protect the skin from the outside, it is essential to protect it from the inside.

Optimizing human nutrition for skin health, and for overall health, requires whole foods with their complex milieu of phytonutrients, beyond the essential nutrients. Based on this, we provide the following dietary supplement recommendations to help maintain your skin health.

This dietary supplement contains 10mg of lutein (oil), 2mg of meso-zeaxanthin (oil), 252mg of bilberry extract (25% anthocyanins) (63mg per serving), 8mg of astaxanthin (oil), and 5mg of beta-carotene (oil) per serving, providing beneficial dietary ingredients for eye and skin health.

Perlonfo is scientifically formulated to provide a daily dose of 1200 mg Sea Buckthorn Fruit Oil, 600 mg Sea Buckthorn Seed Oil, 8 mg Lycopene Oil, and 2.9 mg Vitamin E.. It is characterized by containing a complete range of plant-based Omega-3, 6, 7, and 9 fatty acids as a substitute for fish oil, Especially rich in Omega-7, which is known as the "only fatty acid that can significantly alter lipid metabolism changes in adipose tissue",,And provide a 2:1 health requirement ratio of Omega-6 to Omega-3. and is rich in vitamin E, total carotenoids, trace elements, and more., And provide a 2:1 health requirement ratio of Omega-6 to Omega-3.

Plant-based carotenoid

 the plant-based carotenoid β-carotene has been shown to reduce erythema from UV[1]. β-carotene and other carotenoids (lycopene, lutein, zeaxanthin) from plants can be found on the skin and follow seasonal variation. Lycopene, found in red fruits and vegetables, has also been shown to decrease oxidative damage in the skin[1]. Lycopene is negatively correlated with skin roughness due to its role as the most effective carotenoid singlet neutralizer[2]. However, astaxanthin, found in marine life, also conveys UV protection [1]. Regular consumption of astaxanthin was also found to reduce the aging of residual skin surface components, as well as provide photoprotection [3]. The mechanism of action may work by inhibiting the formation of reactive oxygen species and increasing the expression of enzymes that respond to oxidative damage[4].

Vitamin C

Vitamin C is critical for skin health because of its role in stimulating collagen and elastin synthesis and inhibiting melanin production. Vitamin C also protects against UV-A and UV-B by inhibiting proinflammatory cytokines and apoptosis; it also has the potential to protect against several skin diseases such as atopic dermatitis, herpes, and malignant melanoma. Vitamin C also improves hydration in the epidermis[5].

Vitamin D

Both the synthesis of vitamin D (from UV absorption) and active vitamin D itself may have protective effects against UV radiation.

Vitamin E 

Vitamin E (α-tocopherol) protects against oxidative stress in lipids and therefore can be supplemented in patients who have psoriasis and atopic dermatitis . Vitamin E is protective against collagen breakdown in the skin and decreases skin inflammation, while deficiency has been linked to irregular collagen structure and the presence of skin ulcers [6].Vitamin E has been shown to be effective in delaying the growth of skin cancer, improving hyperpigmentation, and enhancing the integrity of epidermal and dermal structures for the delay of skin aging[6].

Fatty Acids

Fatty acids have a very important role in maintaining the skin barrier, pH, andmoisture level. The presence of these fatty acids has been shown to relieve skin inflammation and dryness,epidermal tissue requires an adequate supply of essential fatty acids for homeostasis,ω-3 fatty acid supplementation has been shown to be effective, particularly in patients with psoriasis and atopic dermatitis[7]. Additionally, 1.8 g/d of EPA and 1.2 g/d of DHA have been shown to reduce erythema,while 4 g/d of EPA has been shown to reduce UV-induced irradiation and may even reduce the risk of skin cancer. Linoleic deficiency has been linked to skin dryness due to its role in the skin barrier while deficiency of GLA is linked to excessive epidermal exfoliation [6]. There is also some evidence to suggest that a low ratio of ω-6 to ω-3 fatty acids is required for the treatment of atopic dermatitis, psoriasis, and acne. There are more and more promising studies in favor of combined GLA and ω-3 LC-PUFAs supplementation that shows the highest potential in diminishing inflammatory processes and ameliorating chronic inflammatory diseases, as well as the chronic inflammatory skin diseases like AD, psoriasis, acne, and to some extent hidradenitis suppurativa. [8]. Supplemental ω-3 fatty acids are relatively safe (few side effects) and have shown benefits for photoprotection, psoriasis, eczema, retinoidinduced cutaneous side effects, and during chemotherapy.As a final point,fats are required for the absorption of dietary fat-soluble nutrients and phytonutrients.
