Did anyone ever tell you that glowing skin can’t just be achieved with external skincare products? Your diet plays a major role in determining your skin’s health. And while there are many superfoods you should be consuming, Vitamin A is a multi-functional vitamin that can benefit your skin at many levels.
From reducing scarring due to acne to the appearance of wrinkles, we tell you all about this wonderful nutrient. Read on.
Benefits Of Vitamin A For The Skin
Whether consumed through foods and supplements, or applied through topical lotions and creams, vitamin A has multiple uses and can even address certain skin problems. Some of them are listed below:
1. Prevents Premature Aging
When you eat foods that contain beta carotene  and provitamin A carotenoids , their antioxidant properties destroy the free radicals responsible for breaking down collagen (leading to fine lines and wrinkles). Thus, it prevents premature ageing.
2. Protection Against Damage From The Sun
Consuming adequate amounts of Vitamin A can help protect the skin against damage from the UV rays of the sun. It will make your skin less sensitive to the sun and protect it against sunburn and pigmentation.
3. Promotes Healthy Cell Regeneration
The carotenoids present in Vitamin A -- retinol and retinoic acid -- are vital for the production of healthy cells. Vitamin A is also a known stimulant for fibroblasts, cells that develop tissues responsible for firmness of the skin at the dermis level.
Vitamin A promotes healthy cell production, which strengthens the outer layer of the skin - the first barrier against infections, bacteria and pollution. A lack of carotenoids and Vitamin A can weaken your skin and lead to problems such as slow healing wounds and skin dryness or pruritus.
4. Reduces And Smoothens Wrinkles
Several anti-ageing OTC products and dermatologist-prescribed creams contain retinol (Vitamin A) in topical form. Retinol and retinoic acid are proven ingredients that help fight early signs of ageing. They help generate new cells that produce new collagen . These ingredients stimulate the production of collagen, which can break down due to external factors such as UV rays and pollution.
5. Gives Your Skin A Glow And Even Skin Tone
Using creams that contain Vitamin A can help reduce pigmentation and give your skin a glow. These creams increase cell regeneration that discards damaged and dead cells. Healthier, younger and newer cells rise to the surface, giving the skin an even tone.
Retinoids present in Vitamin A creams work as blockers of the enzyme that produces melanin, the pigment that gives our skin its colour. Reduced melanin production implies an even toned and glowing skin.
6. Controls And Removes Acne
Acne is generated due to clogged pores, bacteria, excess sebum and dead skin cells. These blocked pores are where the acne causing bacteria, Propionibacterium Acnes can breed, leading to acne and blemishes. Vitamin A creams help stimulate cell production and slow down oil production that prevents acne formation.
Whether OTC or prescribed by a dermatologist, retinoid creams and ointments can reduce acne and prevent their reappearance, since they are anti-inflammatory  in nature. Retinoids can also help remove dead skin cells, which prevents the recurrence of clogged pores. Topical retinoids are effective in treating acne for teenagers and adults according to research .
If you need a strong topical Vitamin A cream, ask your dermatologist to prescribe one. It is likely to be more effective and stronger in dosage than OTC ones. It would usually have Retin-A included in the name.
Available Forms Of Vitamin A
Vitamin A is available through various sources, primarily through foods. Retinoids and carotenoids are the main forms of Vitamin A that need to be consumed. Here are some of the main sources:
1. Vitamin A In Foods

Carotenoids are found in plant-based foods such as carrots, leafy green vegetables, sweet potatoes, tomatoes; and fruits including plums, apricots, papayas and mangoes.
2. Vitamin A Supplements And Tablets
Vitamin A can also be consumed as a supplement or tablet. They are available in various versions such as retinoids like retinyl acetate  or retinyl palmitate ; or only beta carotene which is a carotenoid. Others are a combination of both retinoids and carotenoids.
Vitamin A is often found as an ingredient in multivitamin and mineral supplement combinations. It is also added to several products that are fortified with additional nutrients like milk and breakfast cereals.
3. Vitamin A In Topical Creams
There is a range of skincare products that have Vitamin A as an ingredient. These range from anti-ageing creams to sunscreens, anti-acne ointments and even sunscreens and oils reinforced with vitamin A.
4. Vitamin A Oil For The Skin
Vitamin A oil is available in the forms of oils, serums and capsules that can be broken and applied on the skin. However, it is safer to apply a little bit on a smaller area over a few days and check your skin’s reaction. If it works, you can use it all over your face and neck.
