Table 2 provides information on different sunscreen ingredients (non-exhaustive) and the protection they offer against UVA and UVB radiation. In primary sunscreens, sun protection is the main function while in secondary sunscreens (eg, makeup) it is not. Sunscreens can also be considered either primary or secondary. The established benefits of sun protection are considered to outweigh these theoretical risks. Potential toxic or carcinogenic effects of nanoparticles have been raised, however, no adverse effects have been demonstrated. Microsized or ultrafine grades (‘nanoparticles’) of titanium dioxide and zinc oxide have improved ease of application and cosmesis, and reduced white residue on the skin. Are photostable and often combined with photo-unstable ‘chemical’ agents. ![]()
