No, salicylic acid does not generally cause blindness when used in skincare products. Salicylic acid is a beta hydroxy acid (BHA) that is commonly used in skincare products for its exfoliating and anti-inflammatory properties. When used as directed and in appropriate concentrations, salicylic acid is considered safe for topical use on the skin.

However, it is important to note that salicylic acid should not be applied near the eyes, as it can cause irritation and potentially damage the delicate eye tissues. If salicylic acid comes into contact with the eyes, it should be rinsed out immediately with plenty of water.

It is always advisable to read and follow the instructions provided by the manufacturer when using skincare products containing salicylic acid or any other active ingredient. If you have any concerns or experience any adverse reactions, it is best to consult a dermatologist or healthcare professional.
