Essence may be a very noble and sacred thing in most people's minds, but if you know a little about the industry, you will know that the difficulty of making this thing is very low - of course, I don't mean that it is easy to reproduce big-name products one-to-one, because big-name products are not only in pursuit of effect, but also in pursuit of experience, otherwise they may scare most people away when they get on their faces like glue.

Now that we're done, I can talk a little bit about the simple tutorial on making your own toner and serum.

First of all, water - I haven't bought this kind of thing for a long, long time, I don't feel necessary, I don't believe in rummaging through the so-called big-name explosive water (including some unicorn companies I know also start a business with water), most of the ingredients in it are water, then glycerin, butylene glycol, propylene glycol, plus a bunch of softener preservatives, pigments, and even reluctant to add hyaluronic acid, because the cost of hyaluronic acid is more expensive than these things.

Let's first choose a sub-bottle, disinfect with alcohol or potassium permanganate (the author is generally too lazy to sterilize), wash it with purified water after disinfection (if possible, you can put it in a disinfection cabinet), and then add 50 ml of purified water to the bottle, and then add 0.1 grams of polymer hyaluronic acid dry powder, and you're done.

The dissolution rate of polymers is quite slow (three hours to ten hours), and it will become flakes after a while, which is quite disgusting, and the idle boredom can be stirred and stirred with your hands, and the author generally covers it before going to bed at night, and then you can use it the next day.

In winter, the heating at home is too hot, and when the author is allergic, he will use a bottle as a body lotion, and if it is not enough, he can also add some glycerin or squalane and other things.

Well, water is that simple, it's a little harder than putting an elephant in the refrigerator, but it's cheaper, and when it comes to this, there will definitely be many people who say that the book doesn't say that you need a sterile workshop to make cosmetics? Of course, mass production must need a sterile workshop, otherwise the production process will enter the bacteria, storage and transportation links can not be done, and it should not be a big problem to use it together as a family at home, and the cosmetics will enter a large number of bacteria when they are bought back and opened.

If you are really worried, you can buy some preservatives yourself.

As for the essence, it is a little more difficult, I said in the article that the essence is a little thicker water, you need to use 30 ml of pure water, then add 0.2g of polymer and 0.2g of low molecular weight hyaluronic acid, stir together for a while, and then sleep. After waking up, add 3-6g of glycerin (oil skin can not be added), bifida yeast, ceramide 1-3g (lazy can not be added), or niacinamide 1g (white can not be added), stir and stir vigorously, and then go to sleep, a bottle of essence is good.

The above is the simplest configuration, and the other methods of flying away are a little complicated, but they are always changing, and I hope to provide a little reference for friends who like to do it themselves.
