Editor’s note: As always, Skin Inc. magazine recommends that skin care professionals obtain the proper training before offering any new treatments in their skin care facilities.
Author’s note: Studies indicate that a daily dose of 50,000 IU provides safe protection against sun exposure and skin cancer, though it should be noted that excess doses of vitamin A can result in negative side effects, including hair loss, dry skin, nausea and liver damage, and pregnant women should not exceed more than 10,000 IU daily without a doctor’s supervision. Recommend that clients consult with their physicians before starting any supplement program.
Since Albert Kligman, MD, PhD, the late renowned dermatologist, patented the retinoic acid drug tretinoin in 1973, vitamin A is still recognized as the single most proven go-to ingredient for improving everything from acne, wrinkles and collagen synthesis to hyperpigmentation. Even today, following the advent of peptides, peels and stem cells, vitamin A and its retinoid-derivative family continue to reign as the unequivocal gold standard of skin care, particularly in treating photodamage. This tried-and-true ingredient continues to evolve with new applications and outcomes coming to light, helping it continue its reign as one of the most potent ingredients in the skin care professional’s arsenal.
