What does vitamin A do for the skin?

Vitamin A is essential and plays a big role when it comes to the health of your skin. It is engaged in the production of new and fresh cells, which helps your skin look and function its best.

There is an impressive list that proves vitamin A is a great skincare ingredient on the market today.

  • First and foremost, this vitamin effectively enhances the shedding of old skin cells and encourages the regrowth of newer, smoother, and healthier cells.

  • It acts as an exfoliant that can promote both the texture and complexion of the skin.

  • Aside from working on the top layer of the skin, vitamin A effectively works in the dermis to stimulate collagen production.

  • This vitamin helps decrease wrinkles and fine lines and also enhances and thickens the skin.

  • Vitamin A was first FDA-approved as an acne treatment because it helps slow down the production of oil and prevents clogged pores and inflammation by removing dead skin cells.

  • Taking sufficient amounts of vitamin A can protect your skin from damages from the UV rays of the sun. It helps your skin be less sensitive to the sun and prevents it from pigmentation and sunburn.

How to get more vitamin A?

Aside from eating a diet that includes a variety of foods high in vitamin A above, you take other sources to increase the amount of vitamin A as well. 

Supplements

Vitamin A is available in many versions like retinoids or retinyl palmitate or only beta carotene (carotenoid). Or sometimes, you can find supplements that combine both carotenoids and retinoids. Vitamin A is also a common ingredient in vitamin and mineral supplements. Plus, it is added to some products that are fortified with extra nutrients like breakfast cereals and milk.

Topical creams

It is easy to find some skincare products that include vitamin A as an ingredient. These range from sunblock to anti-aging creams or ointments.

Oil forms

Similar to vitamin E, vitamin A is available in the form of oil that can be applied to the skin directly.

However, if you take or apply too much vitamin, this might create unexpected side effects. Avoid taking over 3,000 mcg every day or you might face up to harmful effects like dizziness, nausea, recurrent headaches, blurred vision, etc.

Can I put vitamin A directly on my face?

Of course, Yes. Some vitamin A supplements come in oil forms that you can split and apply directly to the face. But when it comes to topical application, you need to consult your dermatologist before using it. Only try a small patch on a small area for a few days and check your skin reactions.

How to use it?

First, you need to wash your face with a gentle cleanser and dry it with a clean towel. Then wait about 15 minutes before applying a retinol supplement, and only use a pea-size amount on your whole face (do not get it too close to your eyes).

Cautions

If you let both UV and vitamin A into your skin, they will create opposite things. While one heals, the other damages, thereby leaving your skin red and irritated. So, if you are using a vitamin A product, remember to use sun protection and nourish your skin with antioxidants.

The best time to use a retinol cream is at night because it causes fewer skin sensitivities. But if you wake up in the morning and your skin is peeling, red, or dry, you should use it every other night. Note that these effects are common when starting this type of skin treatment.

How much vitamin A should I take for acne?

As mentioned above, vitamin A is likely safe if you take about 3,000 mcg (10,000 units) daily. Remember that vitamin A is available in two different forms, including preformed vitamin A and provitamin A. And the maximum daily dose of 3,000 mcg is related to only preformed vitamin A.

Meanwhile, some supplements often have both preformed and provitamin A forms. In this case, the amount of preformed vitamin A needs to be determined if the amount of vitamin A is safe. But, a vitamin A supplement with higher amounts of vitamin A (over 3,000 mcg) may be safe if a portion of the vitamin A is the provitamin A form.

 

All in all, vitamin A is an essential nutrient for both your skin health and overall wellness. Make sure to consume enough animal and plant foods or supplements containing this vitamin to improve your skin optimally.
