What are the side effects of retinol?

There are many side effects related to the use of retinol and vitamin A, and they range from mild to severe.

If you take too much vitamin A or are hypersensitive to it, you can develop a condition called vitamin A toxicity, or hypervitaminosis A. Vitamin A toxicity can produce symptoms such as dry skin and lips, hair loss, dizziness, nausea, headache, swelling, fatigue, blurry vision, discomfort, bone pain, and vomiting.

More severe symptoms include eye damage, intracranial pressure, bone problems, pruritus (itching), intrahepatic cholestasis, increased calcium levels, and liver damage.

You should not take vitamin A or retinol if you are allergic to or have a hypersensitivity to this supplement, as you can suffer from an allergic reaction.

Talk to your doctor about proper amounts of retinol and vitamin A during pregnancy, as too much during pregnancy can cause birth defects such as a bulge in the skull similar to a brain tumor.
