You asked about the presence and concentration of salicylic acid in Acnestal facewash.

Based on available product information, Acnestal facewash does not list salicylic acid as one of its ingredients. Instead, it contains other acne-fighting components such as:

• Alpha-hydroxy acid (AHA) for exfoliating dead skin cells
• Tea tree oil with anti-inflammatory and antimicrobial properties
• D-Panthenol for hydration and skin repair
• Vitamin E to aid healing and collagen production
• Glycerin for antibacterial effects and moisturizing

Since salicylic acid is not mentioned in the formulation details, it is unlikely that Acnestal facewash contains this ingredient or specifies its concentration.

If you are specifically looking for a facewash with salicylic acid for acne treatment, you may want to consider other products that clearly state this ingredient and its concentration, typically around 1-2% for effective over-the-counter use.

Recommendation: For personalized advice on acne treatment and suitable skincare products, please consult a dermatologist who can guide you based on your skin type and condition.
