Yes, but I'm not sure of the actual amount, and it would have to be quite a way above the RDA as well.
Also eating a lot of Carrots can be a slight issue, as the Beta-carotene Carotenoid, is known to cause gingering of the skin complexion, so I believe. Though you'd need to eat a lot of them, to have that problem. I doubt you eat a load of them anyway.

Preformed vitamin A is rapidly absorbed and slowly cleared from the body. Therefore, toxicity from preformed vitamin A may result acutely from high-dose exposure over a short period of time or chronically from a much lower intake.
Acute vitamin A toxicity is relatively rare, and symptoms include nausea, headache, fatigue, loss of appetite, dizziness, dry skin, desquamation, and cerebral edema. Signs of chronic toxicity include dry itchy skin, desquamation, loss of appetite, headache, cerebral edema, and bone and joint pain. Also, symptoms of vitamin A toxicity in infants include bulging fontanels.
Severe cases of hypervitaminosis A may result in liver damage, hemorrhage, and coma. Generally, signs of toxicity are associated with long-term consumption of vitamin A in excess of ten times the RDA (8,000 to 10,000 mcg/day or 25,000 to 33,000 IU/day). However, more research is necessary to determine if subclinical vitamin A toxicity is a concern in certain populations.
There is evidence that some populations may be more susceptible to toxicity at lower doses, including the elderly, chronic alcohol users, and some people with a genetic predisposition to high cholesterol.
In January 2001, the Food and Nutrition Board (FNB) of the Institute of Medicine set the tolerable upper level (UL) of vitamin A intake for adults at 3,000 mcg (10,000 IU)/day of preformed vitamin A.
