In the face of so many skin care ingredients, it is difficult not to be careful, all want to "fish and bear paws at the same time", such as both anti-aging and whitening, just do not know when "ingredient A" meets "ingredient B", is it to meet the demands, or to go to the bad face?
Regarding the ingredient mixing, the Internet is full of all kinds of grotesque remarks: "Are many so-called "bad face CP" really dangerous operations?" 」 "Niacinamide and VC mixed together can produce niacin that irritates the skin?"
It's time for Ah Fu to come out and line up a wave of thunder for everyone
Part 1
Q: Can acid products be stacked together?
A: It is recommended to choose one acid product at a time according to the skin problem.
Acid can resist the inflammatory response, kill harmful bacteria, regulate pores and sebaceous glands, dissolve and excrete blackhead oil, and have a good effect on mouth closure and chicken skin. Like salicylic acid, fruit acid, and amygdala are the most selected acids.
Salicylic acid is mainly anti-inflammatory and sterile, and discharges blackhead oil. Fruit acid mainly attacks exfoliation and chicken skin. Amygdalacin mainly focuses on acne and mouth closure.
After all, the acid is still peeling off the epidermis, and the irritation is relatively large. Using multiple products to do stacking is likely to greatly increase the irritation to the skin, or make the skin become red and dry, and once superimposed, it may be more difficult to judge whether the irritation is large or small.
However, if there is a need for acids, it is recommended that one product be used for fruit acid and salicylic acid. Even if you have more than one, it is recommended to use one at a time. If you urgently need to use acid products to whiten and remove keratin, you can follow: salicylic acid in the morning, fruit acid in the evening, it is recommended not to mix with Oh ~

Q: Can niacinamide and VC\fruit acid be used together?
A: This is okay, as long as your skin can tolerate it.
Fruit acid/VC products generally have low PH values and are acidic. Niacinamide products are generally weakly acidic or neutral.
Intervals that are too short will cause the PH value of the fruit acid/VC product to be widened, and the permeability effect will be weakened or even invalidated.
It is recommended to use fruit acid/VC first, wait for about 5-10 minutes, wait until the PH value of the skin returns to weak acidity, and then use products containing niacinamide.
⚠️ Affaulture debunked the rumors
Many people say that niacinamide and VC mixed together produce niacin?
First of all, the production of niacin requires a strong acidic environment, and it also requires a high temperature of about 80 degrees, continuous heating for more than 75 hours, and our face does not have this condition. So worried about niacin irritating the skin? Duck doesn't have to~
When the content of the two ingredients is low or low, it is possible to try, but it is limited to the oil skin of the skin that is too thick, and the baby with the fragile dry skin and sensitive skin of the skin should try not to toss it!
Part 3
Q: Can retinol and VC be used together?
A: Do not use it consecutively, it is recommended to use VC with sunscreen in the morning and retinol in the evening.
Retinol (commonly known as A alcohol), as a classic and efficient anti-aging ingredient, is highly sought after by everyone. Retinol and VC are both very beneficial skin care ingredients and are highly recommended.
However, because retinol is irritating, not all whitening ingredients can be stacked, and it is necessary to avoid stimulating whitening components, such as high-concentration prototype VC and high-concentration 377.
The reason why the use of prototype VC is large is that it can only achieve good results at low PH (3.5 or less), and it is not quite the same as the best effect of retinol PH (around 5.5 - 6.5), so it is not too recommended to use both ingredients at the same time. However, VC derivatives perform well near PH=7 and can play a role under weak acidic conditions, so it is not contraindicated.
If you are still not at ease, you can be between VC products and retinol products for 10-30 minutes, but it is more recommended that you use VC with sunscreen in the morning and retinol at night.

Q: Can peptides and VC be used together?
A: It is recommended that peptides should not be used with high-concentration prototype VC products
Peptides and A alcohol, bosein and known as the three major titans of the anti-aging world, peptides are actually small molecules of protein, is composed of amino acids, because of the characteristics of small molecular weight, smeared on the skin is easily absorbed by the skin, through the skin to act on the dermis layer. It increases skin tissue and accelerates cell regeneration, making it the mainstay of high-end anti-aging products. Common peptides are acetyl hexapeptide-8 (hexapeptide, botulinoid), blue copper peptide and the like.
Peptides have the best solubility at PH 6-8, and many high-concentration prototype VC products have a PH value of less than 3.5, which will affect the dissolution and absorption of peptides. And peptide products are very expensive, if paired together to play a role of 1 + 1 less than 2, it is better to use separately.

Part 5
Q: What ingredients can blue copper peptides not be used with?
A: Do not use with chelating agents, fruit acids, antioxidants, and whitening ingredients.
Then peptides, and by the way, blue copper peptides
Blue copper peptide is a polypeptide (tripeptide-1) plus a copper ion combined with something that allows copper ions to follow the east wind of tripeptide-1 and promote the skin's absorption of copper ions. Therefore, the anti-inflammatory and anti-aging repair effect of this combination is relatively good, which is very suitable for sensitive skin.
The blue copper peptide can win in the polypeptide, thanks to this copper ion, which also causes it to become a very squeamish component.
Chelating Agent: Disodium EDTA is a chelating agent that can rob the copper ions inside the blue copper peptide, resulting in failure.
Acid components: fruit acid, salicylic acid, etc., copper particles can also be chelated partly.
Antioxidants and whitening ingredients: Most of them contain double bond structures, which may be accelerated by oxidation when encountering metal ions, resulting in failure.
Blue copper peptides can be anti-inflammatory, antioxidant, promote collagen synthesis, the effect is powerful, but the price is high, difficult to store, difficult to match, so in the wait and see the little sisters of blue copper peptide must do their homework, otherwise the delicate blue copper peptide is likely to be absorbed before it is inactivated.
Similarly: the sprays of Avène and Skin Springs contain a lot of metal ions (mainly natural spring water/glacier water), so like blue copper peptides, it is not suitable for use with the several ingredients mentioned above.
To be continued...
√ Sensitive skin babies face some more irritating ingredients, such as high-concentration prototype VC, retinol, acid ingredients, choose one of them as the main effect of skin care.
√ If several irritating ingredients appear in a product, there is no need to worry, because the product will ensure the rationality of formula concentration, activity, etc. before the product is listed, but if two irritating products, remember to use them separately.
√ a baby with serious skin problems, first solve a problem, and then solve the remaining problems, do not try to solve it at the same time, such as the recommended solution order of A skin is: first consider acne removal, then solve acne scars, and finally consider whitening.
√ Because everyone's skin state will have different degrees of differences, many CP for skin-tolerant babies, the two combination has a "1+1>2" skin care effect, if not tolerated, impulsive superposition, it is easy to be hurt by this CP, resulting in "1+1<2" negative effects, so be sure to try and gradually establish tolerance!
Having said all this, what Ah Fu wants to say most is that in skin care, in fact, "putting aside the dose to talk about the effect is to play hooligans", no matter whether we want the effect or the toxicity we are worried about, it is closely related to the concentration \ dose. You can't kill all the collocations in one fell swoop, in the final analysis, it still depends on your own tolerance.
The Internet has a lot of true and false claims, there are too many so-called "bad face CP" and "immortal CP", is there enough data and cases to support these claims? These require us to polish our eyes, stay awake, not credulous, not blindly follow, in order to find the real skin care products that are suitable for us, and take fewer detours in the process of skin care!
