Is the effect obvious after Xi Shimingyuan used it? Is it functional or maintenance? I bought the stock solution. Can it replace the essence?

The stock solution is different from the essence.

The so-called stock solution is higher and purer than the essence. Therefore, it is also called the essence of essence. One bottle of stock solution contains more nutrients than three bottles of essence.

Van Gogh's stock solution is pure water solution, which does not contain any emulsifier, mineral oil or artificial pigment. Natural color, almost tasteless or with the characteristics of raw materials; Water-soluble micromolecule system helps the effective ingredients penetrate into the deep layer of skin faster, with the strongest penetration, no oil components, good skin-friendliness and instant absorption. Substances existing in human body or natural plants are used as the stock solution, and the safety is guaranteed. The functional ingredients are single and clear, easy to use, free of burden on the skin, suitable for all skin types, free from allergic phenomena, convenient to match with other products to select the most effective active ingredients, high in active substance content, clear in function and obvious in effect.

Essence is similar to emulsion, and its composition is very complicated. Most of them contain emulsifier, mineral oil or animal and vegetable oil, essence and pigment. Because it contains animal and vegetable oils, it is slow to absorb, which is easy to lead to an increase in allergens and may cause allergies. There are usually supporting products, so you need to use the whole set of products. It is not recommended to mix with other products, and it will affect the effect if used alone.
