BP's shelf life doesn't matter whether it's opened or not. It's still got an expiration date.

Cleanser and jojoba you can use for years as long as you store them in a cool and dry place.

Moisturizer and AHA also don't have a specific expiration date, but to make sure you're using fresh stuff, I would give them a max of about 3 years. Again, doesn't matter if they were opened or not.

What does the number on the bottom of the 6oz AHA bottle mean?

How do I check the expiry/manufacturing date?

That is the lot number. There is no expiration. It contains no active ingredients that would break down over time. The product is designed to remain stable, so as long as it's stored properly and shows no signs of spoilage, you can continue using it. You want to use any product you buy within 2 years or so, but there is no expiration date printed on products that do not contain active ingredients.

I have a bottle of AHA that says it expired Dec 2023. It is unopened. It's the last bottle of AHA I have left. Is it safe to use?

Also, I read somewhere on Amazon by acne org that there is a grace period of 6 months for BP after the expiration date. I have a few bottles of BP that expired in Nov 2024. Does that mean I can use them until May 2025?

The expiration date is the date until which I can guarantee the products optimal performance and quality. After this date, the product may begin to lose some of its effectiveness.

For the best experience and results, I recommend using it within the date indicated.
