If sunscreen absorbs UV light, does that mean that sunscreen makes you warmer?

I have read that what makes sunscreen work is partly that it absorbs UV light. As everyone knows, objects in colours that absorbs visible light gets warmer in the sun (like a black t-shirt). Does that mean that you get warmer in the sun with sunscreen than without?

No. The UV would have been absorbed by your skin. Instead it is absorbed by the sunscreen. The same amount of energy is absorbed either way, so your temperature is unaffected. Some sunscreens increase the amount of radiation reflected, so those would actually lower your temperature.
