Yes. UIG+ has UV protection.
"Ultima Interior Guard Plus is the first and only sealant boosted by Polycharger

for automotive interiors. This Ultima sealant protection will last for months and requires only a damp cloth or Ultima Detail Spray Plus to clean and maintain. Ultima Interior Guard Plus seals and protects leather, vinyl, plastic and wood trim. Moreover, resists staining, water damage, and the effects of oils and salt from the skin. The formula is eco friendly and provides UV protection to prevent drying and cracking of interior surfaces. What’s more, is that unlike traditional interior dressings, Ultima Interior Guard Plus maintains an even, natural appearance, and will not fog your interior glass"
However, it's been suggested to take all "UV protection" in car care products with a grain of salt. Basically, nothing can stop the power of the sun. I'd recommend using the product and cleaning the surface more frequently if your concerned. Parking in a garage will help.
I don't like dressings or "conditioners" for interiors (especially for seats), since for the most part they retain dirt.
