Deep immersion in world pH: what this and its impact on health your skin
pH — this indicator reflects acid-alkaline balance solution. Scale pH varies from 0 to 14, where indicator 7 designates a neutral level. Values below 7 indicate an acidic environment, and above 7 — an alkaline. Level pH is necessary for the maintenance of a natural protective barrier skin called acid mantle, which protects from harmful microorganisms and retains moisture. Skin humans have a natural pH, which ranges from 4.5 to 5.5, which makes it slightly acidic. This perfectly helps prevent the multiplication of bacteria and maintains healthy skin.

Anatomy pH and cosmeceuticals: how ingredients perform their work
Active ingredients in cosmetic forms, such as vitamin C, retinol, and salicylic acid, have their unique optimal levels of pH for ensuring effectiveness. For example, vitamin C, when presented in the form of ascorbic acid, shows maximum stability and effectiveness at a pH below 3.5. In contrast, retinol better reveals itself in a more neutral environment with a pH of around 5.5 in order not to lose its beneficial properties. Incorrect level pH can neutralize active components, making them less effective or even useless. Studies show that more than 60% of users do not achieve the desired results due to the incorrect pH of their cosmetic products.
Preservation quality: how pH affects stability cosmetic formulas
Cosmetic formulas require careful adjustment of pH levels to ensure stability and long-term effect. Incorrect levels can lead to a breakdown of the formula, a change in color and odor product, and a reduction in the effectiveness of active ingredients. For example, acids, such as AHA (alpha-hydroxy acids), are effective only in a strictly defined range of pH. If pH exceeds the norm, acid can completely lose its exfoliating properties. Studies show that 70% of anti-aging formulas do not correspond to declared effectiveness precisely due to incorrect levels of pH. More about alpha-hydroxy acids.
Types skin and pH: individual approach to each type
Different types of skin can react differently to cosmetics with different levels of pH. Oily skin, as a rule, has a higher pH than dry, which significantly affects the selection of suitable means. Acidic products are often more beneficial for oily skin, helping control the secretion of sebum and cleaning pores. Dry and sensitive skin requires more gentle formulas with pH that are maximally close to natural level skin in order to avoid irritations and support level moisture. Recommended studies demonstrate that more than 50% of users make mistakes in selection means for their skin due to insufficient understanding of level pH.
How to choose cosmetics with necessary pH for your type of skin: main recommendations
When choosing cosmetics, it is extremely important to consider their pH and compliance with your type of skin. For oily and combination skin, products with a more acidic pH level are recommended to help control the production of sebum. In the case of dry and sensitive skin, it is better to stop on means with neutral or slightly acidic pH in order to avoid possible irritation. Regular use of pH-neutral cleansing promotes support of acid mantle skin and prevents the loss of moisture. According to statistics, more than 80% of dermatologists advise their patients to consider level pH when choosing means of care. Find out more about human skin.
Cosmetic products and their pH: popular examples for maximum effectiveness
- Serum with vitamin C: Usually has a pH of around 3, which allows vitamin C to effectively penetrate into the skin and quickly exert powerful antioxidant action on a cellular level.
- Tonic with glycolic acid: Has pH in the range of 3.5-4, which promotes effective exfoliation and active renewal of cells of the skin, providing a fresh look and natural glow.
- Cleansing means with salicylic acid: Has pH around 4.5, which allows the product to thoroughly clean pores and significantly reduce inflammatory processes, improving the overall structure of the skin.
What happens when pH composition does not suit your skin: potential problems and risks
Inappropriate pH levels can lead to various problems, including irritation, redness, and allergic reactions. For example, the use of too much acidity on sensitive skin can cause burning and inflammation. Alkaline products, such as soap with high pH, can destroy acid mantle skin, making it more vulnerable to infections and dehydration. According to surveys, more than 40% of users, one way or another, face skin problems due to incorrect pH cosmetics. More detailed about health skin.
