The scrub creams provided in examples 1-3 have significantly reduced water loss through skin and sebum content, and exhibit excellent exfoliating, moisturizing and oil control effects, while showing that the scrub creams provided in examples 1-3 are effective in preventing the loss of a cuticle film during the use of the product.

As can be seen by comparing example 1 with examples 4-9, the scrub creams provided by examples 4-9 have large water loss and small change in sebum content, indicating that the same excellent effects of exfoliating, moisturizing and oil control as example 1 cannot be achieved, indicating that the choice of scrub agent is important for the efficacy of the product, and when the scrub agent is a combination of solid sugar and solid alcohol, the scrub cream shows excellent efficacy, indicating that the combination of solid sugar and solid alcohol has synergistic effect.

As can be seen from the comparison of example 1 with examples 10-14, the base oil affects the degreasing effect of the scrub, and the degreasing effect of the scrub is deteriorated in the absence of any one of the components of synthetic oil, mineral oil and vegetable oil; the vegetable oil is the most main factor influencing the moisturizing effect of the scrub cream, and when the rose fruit oil and/or the sea buckthorn fruit oil are/is lacked, the moisturizing effect of the scrub cream is obviously reduced; the compound of the synthetic grease, the mineral oil and the vegetable oil has the synergistic effect, and the effects of moisture retention and oil control can be realized.

As can be seen from the comparison of example 1 with examples 15-20, the composition of the synthetic oil and fat, the composition of the mineral oil and fat and the composition of the makeup remover all affect the oil-controlling and moisturizing effects of the scrub cream.

As can be seen by comparing example 1 with comparative examples 1-3, the composition of the scrub significantly affects the efficacy of the scrub; the scrub cream adopts solid sugar and solid alcohol as scrub agents, and the scrub cream is massaged and kneaded through particles, so that deep cleaning is realized, and the exfoliating of aged keratinocytes can be effectively promoted; when aged keratinocytes are exfoliated, the scrub agent, the base oil, the thickener and the makeup remover are mutually matched to realize synergistic interaction, and when solid alcohol and/or solid sugar are lacked, the moisturizing and oil controlling capacity of the scrub cream is weakened.
