When it comes to acne, it is simply a nasty ghost that sisters are rushing to escape, lest they can't avoid it! However, in addition to making us ugly, acne can also reflect the problem of excessive oil secretion (water and oil imbalance) or inadequate cleaning on our face!
Not only that, the acne-causing ingredients often mentioned by the editor are also likely to be the "behind the scenes" that cause acne on the face, so if you want to reduce the probability of acne-prone skin care products, you can do your homework and choose some acne-causing ingredients. Low-risk skin care products.
The method is also simple, open the beautiful practice APP/transparent label APP/true self APP. . . Find the corresponding logo in the ingredient list, and you can judge the risk of acne caused by skin care products~

However, it is precisely because there is such a simple method to find out the ingredients that may cause acne that everyone has formed an inaccurate concept:
Any product that contains acne-causing ingredients will definitely give me breakouts! ! !
NO! Every time I hear someone say this, I feel ten thousand rejections in my heart! The popular science of acne-causing ingredients is urgent. Today, the small class starts again. Let's see how much the sisters know about acne-causing ingredients?
What causes acne-causing ingredients to cause pimples on the face?
The formation of acne may be caused by a variety of reasons, one of which is acne formed after the use of cosmetics, which is named "cosmetic acne" by Dr. Kligman in the United States.
(1) The sebaceous glands are stimulated by acne-causing ingredients, the keratinization rate is too fast, and the waste keratin that is eliminated by the skin is produced in large quantities.
(2) The acne-causing ingredient itself has a sealing property, which delays the normal shedding of keratin.

In both cases, waste keratin accumulates in the ducts of the pilosebaceous glands and eventually blocks the ducts. The excess oil cannot be cleaned, oxidized and attached by microorganisms, forming acne. (Fundamentally, the abnormal accumulation of keratin leads to excess oil secretion)
In addition, long-term and too frequent use of facial scrubs, or too rough action when applying makeup, may cause acne breakouts. (Be gentle!)
What are the common ingredients that may cause acne?
Acne-causing ingredients can also play a positive role in skin care products, but you can't kill them with one stick!
At present, the most reliable and commonly used acne-causing detection method is the rabbit ear test proposed by Dr. Kligman in 1972 (rabbit ears simulate human skin). This method has now been refined many times, and it is used to detect most of the "acne risk" coefficients in cosmetic ingredients.

Key words: emulsification; occlusion
Stearic acid is a relatively advanced fatty acid that can emulsify in skin care products, and is generally found in creams and lotions. It will form an oil film on the surface of the skin, which has a certain moisturizing effect and is also relatively strong in sealing.
It can also react with alkalis to form soap bases in facial cleansers, but since it stays on the skin for a short time, there is no need to worry about its acne-causing properties in cleansers.
Keywords: creamy texture; very low risk of breakouts
Skin care products can create a creamy texture, mostly thanks to cetearyl alcohol. It often appears as an emulsifier and thickener, responsible for improving the spreadability of products. Oil-in-water emulsions are occlusive, but the risk of acne is very, very small, so you don't have to worry too much.
Key words: refreshing; irritating
This low-molecular-weight monolipid component can increase the ductility of the product, and it will not produce greasy feeling, and the skin feels very fresh.
But at the same time, its irritation will also break the balance rate of the normal replacement of keratin, so there is the possibility of causing acne. If it is more serious, the skin will become rough and sallow due to keratinization.
Key words: function-rich; irritating
Octyldodecanol is very versatile and can be used in skin care products as a lubricant, emulsifier, solvent and thickener.
However, even if it can be called a "magic oil" in terms of optimizing the feeling of use, it may irritate the skin, accelerate the exfoliation and accumulation of keratin, and cause acne.
Key words: cleaning power; irritation
It is a synthetic ester with very stable performance and can easily penetrate into pores to clean oil and dirt. It is deeply loved by cleansing oils~
However, if it is used excessively, it can easily lead to the accumulation of sebum secretions and hair follicle epithelial cells, which may eventually form keratinization of the hair follicle, and there is also a risk of acne. When using products containing these ingredients, remember to control the amount and frequency~
Key words: anti-aging moisturizing; occlusive
I finally have a name that looks very friendly! The role of coconut oil in skin care products is not limited to skin feel, it can also limit the action of metalloproteinases, slow down the pace of its decomposition of collagen, and play an anti-aging effect.
In addition, it also has a good moisturizing effect, so it has a strong sealing property and also delays the normal replacement speed of keratin.
Are natural oils and fats less likely to cause acne?
The higher the saturated fatty acid content in the oil, the higher the possibility of causing acne. The coconut oil mentioned by KK is a representative ingredient. However, the more common sunflower seed oil and safflower seed oil have less saturated fatty acid content, so they are not easy to cause acne.
I would also like to remind everyone here that a considerable number of ingredients, although they have "oil" in their names, are not actually oils, such as jojoba oil (wax) and tea tree oil (essential oils are not oils). . .
Does using skin care products that contain acne-causing ingredients always cause acne?
Not necessarily, it has to do with personal skin.
KK has also seen that no matter what kind of skin care products (including many containing acne-causing ingredients) are used, there will be no acne, at most a few small closed mouths.
Whether a certain acne-causing ingredient will definitely make acne come to you, KK can't make a conclusion. After all, everyone's skin is different, and their sensitivity to a certain acne-causing ingredient is also different~ But there are no skin care products with acne-causing ingredients. Using it will reduce the probability of acne, and it will definitely give you an extra layer of peace of mind!
