Effect experimental example 1 after-sun repair effect verification
60 volunteers who did not coat sun-screening cream and played outdoors for one day were used to verify the efficacy of the sunscreen cream of examples 1-3 of the present invention, and the sunscreen cream of the present invention was applied on the second day after sun-screening, and the effect was observed after two weeks.
The after-sun repair effect is divided into three grades:
the effect is obvious: the skin turns obviously from black to white, becomes tender and restores the skin state before the sun.
The effect is general: the skin has whitening effect, but the skin state before sunburn is not recovered
No effect is achieved: the skin did not whiten, there was no change in moisturization, but there was no sign of darkening.
The results of the effect experiments are shown in the following table:
