Skin pH balance is a crucial factor in maintaining healthy skin. The skin's pH is generally considered ideal within the slightly acidic range of 4.5 to 5.5. This pH range helps form an 'acid mantle,' which is the skin's natural defense mechanism against external irritants and harmful microorganisms. This acid mantle protects the skin from external stimuli, inhibits the growth of harmful microorganisms, and ultimately protects the skin. Therefore, many dermatologists and skincare products emphasize a slightly acidic pH, which can be beneficial for all skin types, but it is particularly important for those with sensitive or problematic skin.

Why is slightly acidic good for skin?

1. Strengthening the skin's protective barrier
A slightly acidic environment optimizes the protective barrier function of the skin and promotes the growth of healthy skin cells. The acid mantle, the skin's natural defense system, plays a crucial role in protecting the skin from contaminants and harmful bacteria from the outside. Using highly alkaline products can damage this protective barrier, making the skin dry, prone to inflammation, and increasing the risk of infection.

2. Reducing irritation
Using products that are close to the skin's natural pH, which is slightly acidic, can reduce skin irritation. For example, products like cleansers are less likely to irritate the skin when they are slightly acidic. They help keep the skin soft and moisturized. This is especially recommended for those with skin conditions like atopic dermatitis or rosacea.

3. Moisturizing effect
When the skin's pH is properly maintained, the performance of the skin's natural moisturizing factor (NMF) is optimized. NMF helps the skin moisturize itself, and these components can work effectively when the pH is slightly acidic. Therefore, using slightly acidic products reduces moisture loss from the skin and improves overall skin health.

Is it good for acne skin?

Acne-prone skin requires particularly careful management, and it's important to consider pH balance when choosing products. The skin's natural pH is slightly acidic, and maintaining this environment strengthens the skin's defenses and inhibits the growth of harmful bacteria. Therefore, using slightly acidic products can be beneficial for acne skin care.

Acne is caused by a complex interplay of excessive skin oil, dead skin cells, and bacteria that cause infection. Slightly acidic products can help inhibit the activity of these bacteria. In addition, slightly acidic products minimize factors that irritate the skin and contribute to maintaining healthy skin. If the skin becomes too alkaline, the skin barrier weakens, making it more susceptible to inflammation and exacerbating acne.

However, not all acne-prone skin reacts the same way. While slightly acidic products can be beneficial for most acne-prone skin, it can react differently depending on individual skin conditions or skin types. Especially if you have severe acne or sensitive skin, it is best to consult with a dermatologist before using any product. A professional can accurately diagnose your skin condition and recommend appropriate products.

When using slightly acidic products, check if the pH level is indicated on the product label and, if possible, choose products containing natural ingredients. This can help prevent additional skin irritation. By choosing and using appropriate slightly acidic products for acne-prone skin in this way, you can maintain skin health and have a positive impact on acne improvement.

Cautions for slightly acidic products

Although slightly acidic products have many advantages, there are a few things to consider before using them. First, not all skin has the same pH, so there may be some variation depending on individual skin conditions. For example, excessively dry or oily skin may require slightly different pH levels. Also, some people may need products with higher or lower pH levels due to specific skin conditions or diseases. In these cases, it is important to consult a dermatologist to choose the most appropriate product for your individual skin condition.

When choosing slightly acidic products, check the product label to see if the pH level is indicated and, if possible, choose based on the recommendations of a dermatologist. In this way, you can achieve optimal skin care that suits your individual skin condition.
