Ordinary Lactic Acid 10% 30 ml Lactic Acid Surface Exfoliating Formula Lactic acid, an alpha-hydroxy acid, serves as an exfoliant for the skin. This formula, with a 10% lactic acid concentration, provides gentle exfoliation and includes purified Tasmanian pepper, known to alleviate inflammation and allergy symptoms commonly associated with exfoliation. The formula integrates a Tasmanian pepper derivative to help minimize irritation linked with acid use. This plant-based derivative may display a variation in color depending on the season, which can sometimes be noticeable in the product. Contraindications: Avoid using lactic acid on sensitive, flaky, or compromised skin. Please consult the Additional Sun Protection Note and other cautions in the provided instructions. The solution has a pH of approximately 3.8. Lactic acid’s acid dissociation constant, also 3.8, is crucial in acid formulation. This constant indicates the acid’s availability. When this constant matches the pH, there’s an optimal balance between salt and acidity, enhancing the acid’s effectiveness while reducing irritation. A higher pH can lead to excessive salt, causing more irritation compared to a slightly more acidic composition. Note: Although lactic acid offers rapid visible improvements, we recommend opting for indirect skin exfoliation methods instead of direct forms like this combination due to possible inflammation and acid-related allergies. Consider using non-acidic alternatives for gentle skin treatment. Usage Apply once daily, preferably in the evening. It can be mixed with other treatments to lessen its strength until the skin adjusts. Avoid use on sensitive, flaky, or compromised skin and keep away from the eyes. Limit both the frequency and duration of contact with the skin. If irritation occurs, stop using the product and consult a doctor. Use only on intact skin as directed. A preliminary patch test is recommended before full use. Keep out of children’s reach. Sunburn Warning: This product contains alpha hydroxy acid (AHA), which may heighten sun sensitivity and increase the risk of sunburn. During product use and for a week afterwards, apply sunscreen, wear protective clothing, and limit sun exposure.
