Expired Product: Salicylic Acid Cleanser

Hello, I want to ask if, its safe to use an expired product such as Salicylic Acid Cleanser (Klenzit 1.5% SA Face Wash 🇵🇭)? I bought this last Feb, and the expiry date would be next month, October of 2021. It has no exact date but only month and year. Is it safe to use until October 30/31 of 2021? The amount of the product is likely in the middle or below the middle. Its too liquidy (little goes a long way) so I just use a tiny amount for my whole face. Thanks :D *Btw before, I used this cleanser (or any bha cleansers such as CeraVe or Neutrogena) for my back acne. I leave it there for about one to two minutes then rinse off. My back acne dries up and now they are completely gone. In addition, always have a towel if you're outside for the sweat*
