What are some useful a alcohol skin care products
1. Neutrogena A alcohol night cream
Reference price: ￥89 / 40ml
The first A-alcohol in my life is this - Neutrogena's A-alcohol night cream. I started using it when I was in college. (Anti-aging products are more about relieving aging rather than reversing aging, so you can start anti-aging in your early 20s.) At that time, this and the olay small green bottle were also regarded as the "condor heroes" in the skin care industry. . Later, the formula of the little green bottle was changed, and it became the light-sensitive white bottle that we know now. So why do people like to use these two together? The main reason is that they both have anti-aging effects, and alcohol A can also assist nicotinamide whitening by accelerating the metabolism of the stratum corneum. It can be said that they join forces, "double kill". However, before using this combination, you must pay attention to whether you can tolerate it. You can apply less at the beginning and use it for a longer period of time. Once you confirm that you tolerate it, you can gradually increase the dosage and frequency of use. Finally, let’s talk about the skin feel of this product. Although it is a facial cream, it has a matte texture after applying on the face. It is not greasy at all, and babies with oily skin can also hold it~
2. Roc Anti-Wrinkle Eye Cream
In addition to Neutrogena, Roc's A-alcohol products are also very suitable for beginners. I have used its anti-wrinkle eye cream. The effect is not particularly amazing, but it basically maintains the condition of the eye area and no fine lines appear anymore, which is pretty good.
3. Cerave A Alcohol Essence
Reference price: ￥105 / 30ml
This A Alcohol Essence from Cerave was my old favorite last year. Generally speaking, A-alcohol products tend to be more irritating and not suitable for sensitive skin. But if you only have mildly sensitive skin and really want to try alcohol A, you can try this one. It does not add A alcohol directly to it, but wraps it. The last thing added to the product is A alcohol and ceramide complex, with a concentration of 1. This can play a sustained-release role, allowing the effect of A-alcohol to be slowly released little by little, instead of being released all at once, thus avoiding severe irritation to the skin. I tried it on chicken legs with sensitive skin before, and she said there was really no tingling sensation on her face. In addition, I also like the pressing head of this model. Not only is it easy to take, but it is also sealed with a silica gel ball, which can reduce the entry of air and further protect the activity of alcohol A. Having said so many advantages, let’s talk about the disadvantages. When I first put it on my face, it always floated on my face and was difficult to apply evenly. It didn't feel "well absorbed". I don't know if it was because I used too much. However, when I woke up the next morning, my face felt dry and the oiliness was also reduced. After using this one, one of my feelings is that the pores look a little finer visually.
4. La Roche-Posay RedermicR A Alcohol Eye Cream
Reference price: ￥190/15ml
La Roche-Posay RedermicR A Alcohol Eye Cream, I have repurchased it many times before , and now the one in my hand is almost empty. The entire RedermicR series follows the "mild anti-aging" route, so the concentration of alcohol A in the formula must not be too high. This eye cream contains a total of 0.3 vitamin A ingredients: 0.1 is A alcohol, which ensures the basic anti-aging effect; the other 0.2 is A ester, which can take effect slowly and maintain the anti-aging effect. Other highlights include adenosine and caffeine, both ingredients that promote circulation and metabolism around the eyes. It is also fragrance-free and generally mild. Its texture is relatively light and thin, easy to spread, and has good ductility. It is more suitable for use in this season. In winter, you may need to cover it with a more moisturizing eye cream.
By the way, RedermicR also has a facial serum with packaging ingredients that are very similar to this eye cream. The difference is that the facial essence contains less caffeine and contains capryloyl salicylic acid to promote absorption. It comes in a 30ml bottle and is very cost-effective.
In addition, Redermic also has Redermic C, which focuses on 5 pure VC. I will talk to you about VC next time. In short, I like the entire Redermic product line. I have been using them for many years. I used to buy them through Odai. But according to friends from the brand, this series may enter China this year. I still feel a little hopeful.
Which skin care products contain alcohol A?
1. Neutrogena Vitamin A Night Cream
Speaking of alcohol A, the first thing that comes to mind is Neutrogena’s alcohol A. Night cream is an entry-level A-alcohol skin care product with a low concentration and is very suitable for building tolerance. The most recommended combination is the combination of Neutrogena A Alcohol Olay small white bottle, the legendary Internet celebrity combination of 1, 1, and 2. The whitening and anti-aging effect is very good. In addition, I personally tested that the pores will become smaller. I usually choose these two. Meiya starts. Let’s talk about Neutrogena A-Alcohol alone. It feels good on the skin. The soybean-sized paste can be used all over the face. It absorbs quickly, is refreshing and non-sticky, and is very cost-effective. It is worthy of endless repurchase. In addition, be careful not to use it if you have sensitive skin.
25. cerave A alcohol anti-wrinkle essence
This is a combination of ceramide retinol. It has better skin feel and mildness than Neutrogena, and the price is also very cheap. A very cute product. However, I personally find it a bit muddy when I use it. The toothpaste has a tube-like design, has a lotion texture, is not greasy, is easy to spread, and is a bit muddy, but the price/performance ratio is really high. Moreover, the skin changes can be seen after using it. The pores have really become thinner, and the skin condition is very bright and plump. The price is over 100, what can I say? Buy it now while it is not very popular!
3. Paula's Choice Youth Essence Base Serum
Aunt Paula's product, how should I put it, is quite targeted, but it has always been lukewarm. This was only given to me by someone else. I have never thought of buying this, but it works great. This essence is also based on retinol. The ingredients are very beautiful and the texture is oily. It needs to be massaged to help the skin absorb it. It absorbs quickly and is very oily. It is more suitable for use in winter. You can just add facial cream afterwards. After using it, my skin condition is very good and stable, and it can fade acne marks. The overall use experience can be given 4 stars. If you find the price is right, I recommend buying this!
A alcohol is recommended for 5-star anti-aging
A alcohol works by converting it into A acid in the body. Therefore, in theory, it has the same effect as A acid. A acid is a drug and requires a doctor's prescription, while A alcohol is not a drug, so it can be added directly to skin care products.
But we also see that in order for A acid to achieve a certain effect, there is a concentration requirement (0.025). Therefore, in order for A alcohol to achieve similar effects, the A acid converted from A alcohol must reach a certain concentration. concentration. A alcohol cannot be converted into A acid 100%. A reference conversion rate is A alcohol: A acid = 6:1, which means that to achieve 0.025 A acid, the concentration of A alcohol must reach 0.15. The process is that A alcohol is first converted into A aldehyde at a ratio of 6:1, and the conversion of A aldehyde into A acid is close to 1:1. Of course, this is only theoretical. In fact, individual conversion rates will be different. And even if the concentration of alcohol A in the product reaches 0.15, it cannot be completely absorbed and utilized when applied to the skin.
It seems that the effect is not obvious, but in fact, this is the advantage of alcohol A. Because the biggest problem with A acid is its irritation, A alcohol is not that irritating because it needs to be converted. On the one hand, the concentration of A acid after conversion is relatively low, and on the other hand, because A alcohol is absorbed and converted into A acid takes a certain amount of time, so it is less irritating than giving 0.025 A acid to the skin all at once.
Alcohol A was first patented by Johnson & Johnson. After the patent expired, it became a widely used ingredient in the cosmetics industry.
Its effectiveness has been proven. Although it is somewhat irritating, it is much better than acid A, and there are many mature experiences for reference. It is rated as a 5-star anti-aging recommendation.
In addition, A-alcohol is not very stable, so when choosing products, you should also pay attention to whether the packaging can retain the activity of A-alcohol. It also increases photosensitivity, so it is best to use it at night and increase sun protection during the day. For safety reasons, it is not advisable to use high-concentration VC, fruit acids, and other products that will exfoliate or irritate your skin at the same time.
Five suggestions for purchasing vitamin A products
Many people are considering choosing skin care products containing vitamin A. When purchasing A-alcohol products, you need to pay attention to the following five points:
1. Based on the irritation of A-alcohol to the skin. If you have intolerant skin, you generally choose to start with a low-concentration product. There is no doubt about it.
2. Products with added anti-irritant ingredients such as bisabolol can help relieve irritation symptoms. Therefore, if the product specifically emphasizes low-irritation products, you can consider purchasing them.
3. Product packaging is very important. If it is an open and unsealed package, the activity of alcohol A cannot be preserved. A-alcohol needs to be isolated from oxygen, high temperature, and light to preserve its maximum activity. Therefore, products need to be selected based on this principle.
4. The best packaging is a sealed aluminum tube, which neither oxygen nor light can penetrate. Therefore, it is very beneficial to the preservation of alcohol A.
5. Since the stability standard of A-alcohol does not require 100% activity within the shelf life, the longer the A-alcohol is produced, the lower the content. Therefore, we need to choose the freshest produced A-alcohol. Vitamin A alcohol products!
The above 5 points are the reference standards for choosing Vitamin A alcohol products under the same conditions. The same standard means that the price and the R&D strength of the brand are not taken into consideration. Because some companies with strong R&D capabilities use advanced technology and good formulas for their products, which can add points to the effect and stability of alcohol A.
