By a comparison of FIGS. 7 and 8, it can be seen that the skin wrinkles were significantly reduced after using the skin care products that containing the camellia extract. From the analysis of the infrared shot instrument, the test area ratio of skin wrinkles is 3.362% before using the skin care products, after using the skin care products for a period of time, the test area ratio of skin wrinkles falls down to 1.430%. It says that the skin care product which containing the camellia extract have a good anti-aging, anti-wrinkle effect.
