CE Ferulic acid potency

Question: How long does it remain effective? I do not see an expiration date - I purchased it last June, but stopped using it after a couple months. I would like to start using it again if it is still good.
Answer:

Once the product has been opened and exposed to temperature changes, light and oxygen it begins to loose efficacy. It should typically be used within six months after opening it, however you should still benefit from the product if you were to use it now. Best skin care wishes.
