Hello, I'm crispy~
Everyone knows that the first step to having good skin is to cleanse your face and wash your face carefully.
But when it comes to cleansing, it is inevitable to take out the soap-based cleanser and amino acid cleanser Pk!
Especially since the "amino acids" are on fire, the status of soap-based cleansing has plummeted, and even many people think that "soap-based = bad face"!
But in fact, facial cleansers should be selected according to their own skin type, and at the same time, they must also master the correct use. Today, crispy will give you a little knowledge about facial cleanser
Classification of facial cleansers
Amino acids and soap bases are both cleansing ingredients in facial cleansers, which are "surfactants" that dissolve oils on the skin while being washed away by water.
According to the different surface activities, facial cleansers are divided into four common categories, soap-based type, amino acid type, glucoside type, SLS/SLES type.
Soap-based cleanser
Common ingredients: fatty acids (myristic acid, lauric acid, stearic acid, etc.) + alkali (sodium hydroxide, potassium hydroxide, etc.)
Advantages: clean and cheap
Disadvantages: Irritating, not suitable for dry skin, sensitive skin
Suitable for skin types: oil skin, oil mixed skin occasionally used
The first thing to introduce is the soap-based cleansing that has been demonized by the whole network and has also been blacklisted by many people.
The strong alkaline soap base does have a strong irritation, and the skin is tight and dry after use, which is not suitable for sensitive skin.
But it's not as scary as the legend goes! It is still necessary to analyze it specifically for different skin types
Skin like oily skin and oily skin are very oily, and it is easy to clog pores, acne, blackheads and closed mouths.
The soap-based,000-strong cleansing ability takes away excess oil from pores and is suitable for deeply cleansing the skin at night.
But it cannot be used frequently for a long time, otherwise it will cause the stratum corneum to thin, resulting in damage to the skin barrier.
Crispy pastry is recommended to use it alternately with amino acid cleansing, 2-3 times a week, do not rub it vigorously for too long after applying to the face, and you can wash it off in more than ten seconds.
If it is a large oil field, the frequency of soap-based use can be appropriately increased, depending on the individual's skin condition
Amino acid cleansing
Common Ingredients: Sodium Xyl X acid/potassium (potassium cocoyl glycinate, sodium lauroyl glutamate)
Pros: Mild and not irritating
Disadvantages: weak foaming force, general cleaning power
Suitable for skin types: For all skin types, large oil skins may not have enough summer cleansing power
In recent years, amino acid cleansing can be said to be the popular fried chicken in skin care products, but it is not without reason.
Its pH is weakly acidic, close to the pH of human skin, mild and skin-friendly, the cleansing power is not bad, and it is favored by dry skin and sensitive skin.
However, there is also a difference between amino acid activities, usually in terms of mildness, generally glutamic acid> alanine> sarcosine> glycine.
In addition, when looking at the ingredient list, pay attention to whether the amino acid components are in the front, if it is too far behind, the content is extremely low, which is about the same as not adding fake amino acids to clean the face.
Glycoside type cleanser
Common Ingredients: XXX Glucoside (Decyl Glucoside, Lunar Decyl Glucoside, Cocoyl Glucoside)
Pros: Good cleaning and gentle
Disadvantages: the cost is relatively high, there is a slight sense of film formation
Suitable for: All skin types
Glycoside-type cleansing, also known as APG-type cleanser, as a non-ionic surface activator, takes into account the advantages of less irritation and good cleaning power.
It is even milder than amino acids, but the disadvantage is that the cost is relatively high, and most of these cleansings on the market are in the form of compounds.
After washing the face, there will be a slight membrane feeling, it feels like it has not been washed, and many sisters do not like this feeling.
SLS/SLES cleansing
Common ingredients: sodium lauryl sulfate, sodium laureth sulfate
Advantages: super cleaning power, degreasing power
Disadvantages: It is very irritating and not suitable for dry skin and sensitive skin
Suitable for skin types: Oily healthy skin occasionally used
This type of cleanser is anionic, has a strong cleansing and degreasing power, and will be more common in cleansing, shampoos and shower gels.
Its irritation is never lost to soap base, because the delipidization power is too strong, it is easy to take away the oil of the skin itself,
Long-term use of sensitive skin and dry skin is not recommended
