When thinking of skin care, most people’s first reaction is to wipe skin care products.
However, different from more than ten or twenty years ago, there are many kinds of skin care products on the market now, with different effects and very big price differences. It’s just that if you buy something that is completely unsuitable for you, you don’t have to feel distressed and use your face to hurt. It’s really hard to say.
Therefore, we specially invited cosmetics formulators to prepare such an article. After reading it and joining the collection, we can avoid many pits by choosing skin care products.
I. Facial Cleansing
The main function of facial cleansing is to focus on cleaning, and the washing time is generally not too long, so adding all kinds of gorgeous ingredients to facial cleanser will not have much chance for skin to absorb and will not have much effect.
Instead, take some time to do your homework and understand the main cleaning ingredients of facial cleansing products.
Generally speaking, there are the following kinds of cleansing products on the market:
1. Saponified products
In general, this kind of saponified products will use two main ingredients, that is, Sodium hydroxide; NaOH) and some animal and vegetable oils.
This kind of product has slightly stronger cleaning power and feels drier after washing. It is suitable for oily skin. General skin, dry skin, sensitive skin and problem skin are not suitable.
2. Surface active products
This refers to products made by directly adding some surfactants, such as cleansing soap (cream, foam, liquid, cream, milk and powder), etc. This type of products use a lot of main cleaning ingredients. Here are some common ingredients:
General Type:
Sodium lauryl ether sulfate (Sodium lauryl sulfate), sodium lauryl sulfate (Sodium lauryl sulfate; Sodium Lauryl Sulphate)
Amino acid type:
Sodium Cocoyl Alanine (Sodium Cocoyl Alaninate), Potassium Cocoyl Glycine (Potassium Cocoyl Glycine), Sodium Cocoyl Glycine (Sodium Cocoyl Glycine), Sodium Lauroyl Glutamate (Sodium Lauroyl Glutamate)
Natural plant source type:
Lauryl Glucoside (Lauryl Glucoside), Decyl Glucoside (Decyl Glucoside)
This type of surfactant has weak adsorption on skin cuticle, so it will not cause damage to cuticle. At the same time, the washed skin will feel moist, smooth and not tight, so it is more suitable for dry skin, sensitive skin and problem skin.
Although this kind of cleaning ingredient is mild, the formula should also be as mentioned earlier, and humectants and fat protectors should be appropriately added. The recommended ingredients are as in the previous example.
3. Synthetic & saponified products
This refers to the product of saponified soap with surfactant, so the common cleaning ingredients illustrated in the above two items will appear in the formula at the same time.
This formula design can have the refreshing feeling of saponified products after washing, and will not have the feeling of being greasy and unclean.
II. Creams
1. There is no need to specifically distinguish between day frost and night frost.
Cosmetic technology is actually not fine enough to distinguish day from night.
Of course, if it is sunscreen, it is precisely because it needs to protect the skin during the day to avoid being damaged by ultraviolet rays in the sun, so it is a commodity used during the day.
Other products contain organic acids, which will accelerate skin cutin metabolism. During the use of such products, the skin will be relatively fragile, vulnerable to stimulation or injury, and will also be damaged by ultraviolet rays. Therefore, such products are not suitable for daytime use to avoid serious adverse reactions.
As for general moisturizing or anti-aging products, they do not need to be divided so finely.
2. Cream can replace eye cream
Basically, it is possible, unless the manufacturer has a special statement, the reason is the same as the above problem, cosmetics are not so fine, for cosmetics, there is no difference between the face and the eye circumference.
III. Sunscreen
1. Buying sunscreen depends on these indicators.
Domestic, Japanese, Korean and Taiwan products: refer to SPF value and PA + or PA* mark
American Products:
Refer to the SPF value and whether there is a label Broad Spectrum (Guangpu) for UVA protection. At the same time, if water-resistant and sweat-resistant products are needed, it is necessary to pay attention to whether there is a label Broad Spectrum Water Resistance (40 minutes) or Broad Spectrum Very Water Resistance (80 minutes) (80 minutes)
EU Product Reference:
Only when SPF value is marked can UVA protect it. Similarly, if water-resistant and sweat-resistant products are needed, attention should be paid to whether there is a sign that Water resistance is water-resistant and Very water resistance is very water-resistant.
2. This is the right way to choose sunscreen.
If you are not allergic to chemical sunscreens, I suggest that you do not need to reject chemical sunscreens.
It is better to choose products that have been matched with chemical sunscreen agents and physical sunscreen agents, so that sunscreen products have the effects of blocking and absorbing ultraviolet rays at the same time, thus achieving all-round protection.
Sunscreen products are not selected. The higher SPF and PA values, the better.
According to the research, SPF 15 can isolate 93.3% UVB, SPF 30 can isolate 96.7% UVB, and SPF 50 can only increase the isolation rate of UVB to 98%, thus the sun protection effect will not increase in a considerable proportion with the doubling of sun protection factor.
In theory, the higher the SPF and PA values of commodities, the more chemical sunscreen agents to be added to them, and the higher the risks will naturally be.
Just like why you should take medicine when you are not ill, it is good to choose the right one, and don’t be too superstitious about the sunscreen effect of high-coefficient products.
4. Mask
Although a mask may contain 15-30ml of essence, it is not necessarily all active ingredients.
For example, alpha-arbutin, a famous whitening ingredient, costs about RMB per 1 gram of 10 yuan.
Based on the addition of 2% concentration, the cost of alpha-arbutin alone for a mask containing 30ml essence needs 6 yuan RMB, not including other various ingredients, packaging, manufacturing and other costs.
Therefore, the selling price of goods that are close to the people may be due to the cost, and very few effective ingredients have been added, so the effect is not obvious enough.
Most of the effects of facial mask are moisturizing. As for whitening, wrinkle removal, oil control and other functions, don’t expect too much.
Therefore, for affordable flaky facial mask, it is good to choose those with moisturizing ingredients and those produced by regular manufacturers.
Five, acne removal products
At present, the treatment of acne skin in skin care products is basically biased towards the role of prevention. The effective ingredients commonly used in cosmetic care products are as follows:
Components that promote keratinic metabolism:
Glycolic acid (Glycolic Acid), Salicylic acid (Salicylic Acid), Lactic acid (Malic Acid), Tartaric acid (DL-Mandelic acid), Peptide-Acid complex (Vitamin A Palmitate) and Retinol (Retinol) are common keratinic promoters.
Inhibitory ingredients of acne bacillus:
Sulfur, dl-Mandelic acid, Salicylic acid, Sodium Ascorbyl Phosphate; STAY-C 50), Oleanolic acid (Oleanolic acid), Sebacic acid (Sebacic acid) or Hexamidine Diisethionate (Hexamidine Diisethionate) etc.
Ingredients for controlling oil or reducing sebum secretion:
Sulfur (Sulfur), Niacinamide (Niacinamide) or zinc PCA (Zinc PCA), etc.
Ingredients to reduce inflammatory reaction:
Dipotassic glycyrrhizate, Stearyl Glycyrrhizinate or Alpha-Bisabolol can relieve inflammatory reaction.
Protect the wound:
Chitin (Chitosan) can form a film on the skin surface to protect wounds.
Skin care products are not necessarily the more expensive the better, the more the better, the key is to suit their own needs.
I hope everyone can choose the most suitable skin care product after reading this article!
