[0026] Optionally, the specific preparation steps of the almond shell powder are: putting clean and dry almond shells into the grinding chamber of a ball mill, passing the powder after 12 hours of ball milling through a 200-mesh sieve, and then putting it into a bellows to dry to obtain the almond shell powder.

[0027] Compared with the prior art, the present invention has the following beneficial technical effects:

[0028] The benefits of the above formula and the resulting moisturizer are as follows:

[0029] The present invention has good permeability through hyaluronic acid and glycerin, which can quickly penetrate into the deep layer of the skin and provide a long-lasting moisturizing effect. The permeability of grape seed oil and walnut oil also helps the moisturizer to better penetrate into the deep layer of the skin and provide a comprehensive moisturizing effect. At the same time, grape seed oil and walnut oil have the function of regulating the oil balance of the skin in the formula. They can provide sufficient moisturizing while controlling excessive oil secretion of the skin, regulating the oil balance of the skin, controlling excessive oil secretion, and keeping the skin soft and refreshing.

[0030] By adding cornflower extract rich in anti-inflammatory ingredients, it can relieve skin inflammation and sensitive reactions, reduce skin discomfort, and make the moisturizer more comfortable, gentle and non-irritating during use. It is suitable for all skin types, including sensitive skin.

[0031] By adding propylene glycol and almond shell powder and stirring and mixing, the permeability and absorption of the moisturizer can be enhanced. Propylene glycol has good permeability and can promote the moisturizer to penetrate deeper into the skin better. Almond shell powder can remove the stratum corneum, improve the skin's absorbability, and further promote the penetration and absorption of the moisturizer. It has a synergistic effect, enhancing the permeability and absorption of the moisturizer, allowing it to better penetrate deeper into the skin and provide a long-lasting moisturizing effect.

[0032] The moisturizing aerosol prepared by the present invention can enhance the permeability and absorbency of the moisturizer, allowing it to better penetrate into the deep layer of the skin, providing a lasting moisturizing effect, while controlling excessive oil secretion of the skin, regulating the oil balance of the skin, controlling excessive oil secretion, and keeping the skin soft and refreshed.
