Application techniques

pH level of the product

The primary factor that influences the effectiveness of skin care products is the pH level of the product. Skin care products are formulated to work best at certain pH levels that match the skin's natural acidity, which typically ranges from 4.5 to 5.5. When the pH level of a product is too far from this range, it can either irritate the skin or fail to perform as intended. For example, products that are too alkaline can strip the skin of its natural moisture, leading to dryness and irritation, while overly acidic products may cause stinging or sensitivity.

Understanding pH is crucial for both estheticians and clients, as it helps in selecting the right products for various skin types and conditions. This knowledge allows professionals to recommend products that maintain skin balance and enhance the overall effectiveness of treatments.
