Whether the pH value of the product is neutral or acidic depends on the situation and cannot be generalized. When choosing skincare products, we usually choose products that are neutral or slightly acidic, as our buffering effect against alkaline substances is limited.
1.Facial cleanser: In general, a weakly acidic facial cleanser is better. Because our ** is acidic, the pH value is between to, and the lowest can be reached. Weakly acidic cleansers fit better** and cleanse better.
2.Other supplies: Different ** supplies have different pH requirements.
For example, skincare products containing AHAs can regulate the pH level, remove dead skin cells, and make ** more delicate, but there is no need to worry about using a sunscreen with AHAs, as long as you choose a sunscreen with SPF 15 or higher.
In general, the key to choosing a neutral or acidic product depends on the efficacy and action site of the product.

To determine whether a facial cleanser is acidic or alkaline, you need to do a pH test for the facial cleanser. A good facial cleanser is weakly acidic, so its pH value is generally around the limit, and this value is basically close to the human body**, so it is safer and gentler. Some soap-based cleansers are more alkaline, so they are prone to dryness and allergies after use.
Acidic facial cleanser is relatively milder, and long-term use of alkaline washing shed which milk will accelerate the aging of the **, and will cause damage, but it does not mean that the alkaline facial cleanser has no advantages at all, and the alkaline and posture environment can inhibit the generation of bacteria on the **. However, long-term use may cause skin acne, especially for rough people, using alkaline facial cleanser is even worse.
Acidic facial cleanser is closer to the pH value of the human body, and its foaming is very strong and foamy, generally dry **, oily ** and oily skin can be used, and alkaline facial cleanser is also rich in external foam, compared with acid facial cleanser, its cleaning power is stronger, but some acid facial cleansers with better ingredients will also rub out dense foam, and there will be no tightness after washing, and it can also be cleaned very clean.
Therefore, if it is a large oil field, you can choose a neutral facial cleanser, so that the pH value of ** is closer to the middle value, which will not cause the destruction of the inertia of the skin state, so the use of acidic or alkaline ingredients facial cleanser should be adjusted at any time according to the skin condition.

Facial cleansers of both natures are available. The acidity and alkalinity of facial cleanser is not fixed, there are both acidic and alkaline. Because everyone's skin condition is different, it is important to choose the right facial cleanser according to your skin type when choosing a facial cleanser.

There are several ways to tell if a cleanser is acidic or alkaline:
1. Look at the instructions for use, generally indicating the pH value of the facial cleanser or what skin type it is suitable for.
2. Looking at the shape of the foam, the rubber foam of the general alkaline facial cleanser is relatively large and loose, while the foam of the acidic facial cleanser is relatively small and tight.
3. Look at the feeling after washing, generally alkaline facial cleanser will make you feel clean but tight after washing, while acidic facial cleanser will make you feel soft but not clean after washing.
The first thing to say is that there is no obvious definition of the strength of the acid and base, and it is impossible to measure it by pH, and you have a wrong understanding of this concept. >>>More

Due to the pollution of the atmosphere, acid rain zones began to form in some areas. The acid rain areas in China are mainly distributed in the south of the Yangtze River, the east of the Qinghai-Tibet Plateau and the Sichuan Basin. Acid rain pollution is the most severe in central China, and the average annual pH value of acid rain in the central region is lower than 80, and the frequency of acid rain is above 80. >>>More
