Outdoors, Haitang plans to build a basketball court. The surrounding area can also be used for running, basketball courts, courts, Cuju courts, fighting arenas, rock climbing arenas and various physical training.
Huicong and Datong have seen this, and they helped with drawings, planning of raw materials and site arrangements.
Almost all the nearby land has been used, except for some left by Fangrong, and Haitang acquired some more.
She wanted to step up her plan, but this time she did not refuse the young prince's kindness and used the young prince's funds. The young prince smiled and said that he wanted shares, not money.
Fitness activities such as fighting rock climbing deeply attracted the young prince. Not only was it a lot of fun, but it also enhanced the physical fitness of the soldiers. It was worth emulating. You should also follow suit and plan carefully when you go back.
Datong, Huicong and Zilu helped plan these fitness equipment, and Haitang only had to make the final decision.
Summer has arrived, and sometimes the sun is so hot that it can make people's skin very hot or even black. Haitang thinks it's time to develop some sunscreen, moisturizing and other skin care products.
Applying sunscreen first and then moisturizing will have better results.
I also thought about it, the sunscreen ingredients in sunscreen usually consist of three types, one is chemical ingredients, which are metabolized and absorbed by human skin, the other is physical ingredients, which stay on the surface of the skin, and the last is plant ingredients, which are naturally extracted.
All three are indispensable.
This chemical component is actually not harmful. It needs to enter the skin cuticle. After being absorbed by the skin, it interacts with ultraviolet rays and converts them into harmless energy, so it is called an ultraviolet absorber. Because it is on the skin
A chemical reaction occurs, so there is some irritation to the skin.
Specifically, there is cinnamon-methoxycinnamic acid, which is the most widely used chemical sunscreen ingredient. It can block e. The newer chemical sunscreen ingredient can block uvb
OCS (octyl-salicylic acid) itself is a very weak UVB blocker, so it is usually used together with other UVB sunscreen ingredients to enhance the sunscreen effect.
PABA (para-aminobenzoic acid) can block UVB. It was once widely used, but the rate of allergic reactions was too high, so it is rarely used now. Later, Padimate-O (octyl-dimethyl
-para-aminobenzoic acid), as its substitute, is less irritating and can only block UVB.
The above are commonly used in sunscreens and are not likely to cause allergic reactions. If you use benzophenone-3 and Paso 1789, you are not sure. They have a high chance of allergic reactions. There is no chlorpheniramine these days.
Calamine is difficult to treat if you are allergic to it, and it may even cause death. Begonia will not take such a risk.
Chemical sunscreen contains a large amount of ultraviolet absorbers, and the SPF index is directly proportional to the amount of ultraviolet absorbers contained. The higher the index, the greater the amount, and the greater the chance of causing skin sensitivity.
Physical sunscreen usually stays on the surface of the skin and will not be absorbed or metabolized by the body. Specifically, it refers to using particles in sunscreen to block, reflect or scatter away ultraviolet rays, thereby reducing the amount of ultraviolet rays reaching the skin. Because it does not occur
Chemical reaction, so it is gentler on the skin. But the disadvantage is that if it is applied thickly, the skin will easily look white and unnatural.
Titaniumdioxide (titanium dioxide): can completely block UVB, but can only block UVA with shorter wavelength, and cannot block long light waves.
