Dietary Intake Recommendations The recommended daily intake of vitamin A for women is 700 micrograms, and for men, it's 900 micrograms. Most people can get this amount from the foods they eat. As noted, MINDBODYSKIN offers a daily dose of 6,110 micrograms of vitamin A—the sweet spot for treating acne.
Oral vitamin A and acne
The dosage of vitamin A ranged from 36,000 IU to 500,000 IU per day although nearly half of the studies (44%) reported success with a dose of 100,000 IU/day.
The recommended daily allowance (RDA) for men is 900 MCG REA, or 3,000 international units (IU). For women the RDA is 700 mcg RAE, or 2,330 (IU). For all adults, the Tolerable Upper Intake Level (UL) — the most vitamin A one can take without experiencing negative health effects — is 3,000 mcg RAE, or 10,000 IU.
At doses of 50,000-300,000 IU daily, vitamin A may provide a substitute for acne management when isotretinoin is unavailable.
Vitamin A-Forte 200000 IU plays an essential role in the function of retina and is essential for growh and differentiation of epithelial tissue.
The maximum daily dose relates to only pre-formed vitamin A. Pre-formed vitamin A is possibly unsafe when taken in doses greater than 10,000 units (3,000 mcg) daily. Higher doses might increase the risk of side effects. Long-term use of large amounts might cause serious side effects including mental changes.
Oral vitamin A derivatives
It is an isomer of retinoic acid approved by the Food and Drug Administration (FDA) for treating severe acne vulgaris. It can decrease sebum production, acne lesions, and acne scarring, and it has effectively been used to reduce treatment-resistant acne.
Large doses of oral vitamin A supplements don't appear to affect acne.
Isotretinoin. Isotretinoin is a treatment for severe acne that comes in capsules. It has a number of beneficial effects: it helps normalise sebum and reduce how much is produced.
What supplements should I take daily for acne? A multivitamin containing zinc, vitamin A, vitamin D, selenium and B-vitamins provides essential skin-boosting nutrients to help regulate oil production, inflammation, hormone balance and antioxidant status for preventing acne.
The total vitamin A content of a food is usually expressed as micrograms (µg) of retinol equivalents (RE). The amount of vitamin A adults aged 19 to 64 need is: 700 µg a day for men. 600 µg a day for women.
It was concluded that at least in some western countries chronic vitamin A consumption might represent an appreciable cause of chronic liver disease, the recognition of which mainly relies on expert liver biopsy interpretation.
Apply retinol in a thin layer to your entire face (be careful not to get it in your mouth, nose and eyes). You should use a dose that's about the size of a pea. For the first couple weeks of treatment, apply retinol only every other day. Finish with a facial moisturizer that won't clog your pores (noncomedogenic).
As with most acne treatments, vitamin A takes time to work and you should allow for twelve weeks of use before determining whether or not the product has worked for you. It is also advised that you continue to use vitamin A (if it has proven effective) even after your acne symptoms have improved.
After four weeks, there was a significant decrease in the number of papules, pustules, and infiltrates in the zinc-treated groups. The effect of zinc plus vitamin A was not better than zinc alone. After 12 weeks of treatment, the mean acne score had decreased from 100% to 15%.
Retinol is actually just another word for vitamin A. It is an extremely effective cell-communicating ingredient, meaning the substance can literally attach itself to almost every skin cell and it 'tells' the cells that they should behave like healthy, younger skin cells. Retinol is an antioxidant.
Benzoyl peroxide.
This ingredient kills bacteria that cause acne, helps remove excess oil from the skin and removes dead skin cells, which can clog pores. Benzoyl peroxide products that you can buy without a prescription are available in strengths from 2.5% to 10%.
For moderate to severe acne, you may need oral antibiotics to reduce bacteria. Usually the first choice for treating acne is a tetracycline (minocycline, doxycycline) or a macrolide (erythromycin, azithromycin).
Acne is a common issue for many people, especially for teenagers and young adults in their 20s. Some have mild symptoms, while others can have very severe issues. Acne effects around 90% of adolescents with the prime age across all genders being the teenage years of 14-19 years old.
Dietary Intake Recommendations
As noted, MINDBODYSKIN offers a daily dose of 6,110 micrograms of vitamin A—the sweet spot for treating acne. This is technically 679% of the recommended daily value (DV), but it's far less than doses that have resulted in toxicity. Vitamin A toxicity is actually very, very rare.
The daily biological need for vitamin A is estimated to be 800 retinol equivalents (RE)/d (2667 IU/d) for adult women and 1000 RE/d (3300 IU/d) for adult men; doses ≥7500 RE (≥25000 IU)/d are considered potentially toxic over the long term.
High-dose vitamins B6 and B12 have also been linked to rosacea fulminans, a condition that looks like acne. Rosacea is marked by large red bumps and pustules that typically appear on the nose, chin, and/or cheeks.
Yes, vitamins can help hormonal acne by acting as antioxidants, reducing inflammation, and supporting healthy hormone balance. The best vitamins for acne are vitamin A, vitamin C, vitamin E, and a B complex. You can find many of these nutrients in food, but taking supplements can ensure you're getting enough.
Retinol and Retin-A (tretinoin) are both retinoids — topical forms of vitamin A. Retinol is a common over-the-counter (OTC) ingredient in acne and anti-aging products. Retin-A is a prescription-only acne treatment, but it's used off-label for anti-aging effects, too. Retinol and Retin-A work the same way to treat acne.
