Both P25TiO2NPs (with or without vitamin B2) were not found beyond the epidermis in 99% of the analyzed TEM images (Fig. 8). This is coherent with previous findings showing that nanoparticles greater than 50 nm can not penetrate the skin, even in vivo models with movement, stretching, and friction [54]. However, in one of the zones, a few nanoparticles were observed inside a hair follicle. This could be due to the follicle exposure after the localized rupture of this physical barrier when rats were shaved in order to clean the area for cream topical administration. This finding suggests that nanoparticle-based sunscreen should not be applied on recently shaved or harmed skin, in order to avoid nanoparticle skin penetration.

Firstly, calcium carbonate factories can be categorized into two primary types natural and synthetic. Natural calcium carbonate factories extract limestone, marble, or chalk, all of which are rich in calcium carbonate, from the earth's crust. These materials are then processed through grinding and purification techniques to produce calcium carbonate powder. On the other hand, synthetic calcium carbonate factories create the compound through a chemical reaction between calcium oxide (quicklime) and carbon dioxide. This method is often used when a purer form of calcium carbonate is required.
