The investigation of the change in Sprague-Dawley Rat skin in process of time, being irradiated by UVA(2 joul/㎠) and UVB(50 joul/㎠), some areas were applied with sunscreen (SPF 4. 15. 34) and one was applied nothing, gave me the results as follows ;
1. UVBs were more remarkable than UVAs in the change symptoms of skin structure such as hyperkeratosis, parakeratosis, hypergranubsis and hypertrophy.
2. SPF 4 areas were more similar to the unapplied one in the change of skin structure than UVAs.
3. SPF 15 areas were noticed slight hyperkeratosis at 28th in UVAs, while UVBs showed the same symptom at 7th.
4. SPF 34 areas were noticed nothing in UVAs and UVBs.
From the above results I conclude that the change of rat skin according to irradiation UVB was more remarkable than UVA in the areas of applied nothing
The effective usage of sunscreen is resulted by applying sunscreens of higher-grade than SPF 15.
