Can I buy just the acne treatment?

Hello. This is a dual action product (anti-aging & acne). If you are looking for just an acne product our Benzoyl Peroxide Lotion 5% or 10% delievers results. Use moderately 3 x a week to strat and increase to daily usage once your skin is acclimated and tolerates the treatement. Thank you for your interest in Jan Marini Skin Research products.

WHat is expiration date?

My bottle had an expiration date on the bottom. 09/17.

How does age intervention duality work? The active ingredient is benzoyl peroxide and retinol. I thought this combination cancels each other out?

No. Retinol helps diminish wrinkles. Benzoyl peroxide helps with acne. It can be drying to skin initially. I would recommend starting every other day.

Is the date on bottom the date the lot was produced or the expiration date? I do not see exp listed on there.

On the bottom of mine it says 3/24 so I’m pretty sure that it is the expiration date. Hope that helps.
