Review: Delivered used item - It arrived damaged and used Review: it works - i have tried many products including prescribed acne medication. this is the only one that works without giving me dark spots. i've only had this good results when i took accutane, but i don't want to expose my system for that strong of a medicine anymore. this product has been outstanding and i'm definitely a fan. i'm using it once a day (evening) and i apply a very thin layer only on my problem areas – cheeks and forehead. sometimes i do get an occational pimple, but they dry out really fast. i probably wouldn't get any, if i used this twice a day. the only downside is, that this dries up my skin a little bit and that's why i don't use it both morning and evening. using a really good moisturizer during the day helps for the dryness and helps make up go more evenly. ## Features - A powerful anti-aging acne treatment - Features a unique dual chamber dispensing solution - A remarkable breakthrough in the treatment of aging skin that also suffers from acne. - 28g/1oz - Age Intervention ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B004U5DNMI | | Best Sellers Rank | #86,585 in Beauty ( See Top 100 in Beauty ) #292 in Facial Cleansing Creams | | Brand | Jan Marini Skin Research | | Brand Name | Jan Marini Skin Research | | Customer Reviews | 4.3 out of 5 stars 166 Reviews | | Global Trade Identification Number | 00814924011376 | | Item Volume | 1 Fluid Ounces | | Item Weight | 0.06 Pounds | | Item weight | 0.06 Pounds | | Manufacturer | Jan Marini Skin Research | | Manufacturer Part Number | BP87275962 | | Model Number | G11.1-ACN | | Product Benefits | Anti-Aging | | Product benefits | Anti-Aging | | Scent | Unscented | | Scent Name | Unscented | | Size | 1 Ounce (Pack of 1) | | Skin Type | All | | Skin type | All | | Special Ingredients | benzoyl peroxide, retinol, peptides | | Special ingredients | benzoyl peroxide, retinol, peptides | | Target Use Body Part | Skin | | UPC | 885239552151 814924011376 | ## Product Details - **Brand:** Jan Marini Skin Research - **Item Form:** liquid - **Product Benefits:** Reduce acne and while simultaneously decreasing the apperance of fine lines and wrinkles. - **Scent:** Green Tea - **Skin Type:** Combination, Dry, Normal, acne-prone ## Images ![Jan Marini Skin Research Age Intervention Duality 28g/1oz - Image 1](https://m.media-amazon.com/images/I/61eEkSjv76L.jpg) ![Jan Marini Skin Research Age Intervention Duality 28g/1oz - Image 2](https://m.media-amazon.com/images/I/71wYMo3-anL.jpg) ![Jan Marini Skin Research Age Intervention Duality 28g/1oz - Image 3](https://m.media-amazon.com/images/I/71Dv+EKEh4L.jpg) ![Jan Marini Skin Research Age Intervention Duality 28g/1oz - Image 4](https://m.media-amazon.com/images/I/71f9u9gcBIL.jpg) ![Jan Marini Skin Research Age Intervention Duality 28g/1oz - Image 5](https://m.media-amazon.com/images/I/71kwnTHTlQL.jpg) ## Questions & Answers **Q: Can I buy just the acne treatment?** A: 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. **Q: WHat is expiration date?** A: My bottle had an expiration date on the bottom. 09/17. **Q: How does age intervention duality work? The active ingredient is benzoyl peroxide and retinol. I thought this combination cancels each other out?** A: No. Retinol helps diminish wrinkles. Benzoyl peroxide helps with acne. It can be drying to skin initially. I would recommend starting every other day. **Q: Is the date on bottom the date the lot was produced or the expiration date? I do not see exp listed on there.** A: On the bottom of mine it says 3/24 so I’m pretty sure that it is the expiration date. Hope that helps. ## Customer Reviews ### ⭐ Delivered used item *by L***A on 25 November 2025* It arrived damaged and used ### ⭐⭐⭐⭐⭐ it works *by L***R on 12 March 2013* i have tried many products including prescribed acne medication. this is the only one that works without giving me dark spots. i've only had this good results when i took accutane, but i don't want to expose my system for that strong of a medicine anymore. this product has been outstanding and i'm definitely a fan. i'm using it once a day (evening) and i apply a very thin layer only on my problem areas – cheeks and forehead. sometimes i do get an occational pimple, but they dry out really fast. i probably wouldn't get any, if i used this twice a day. the only downside is, that this dries up my skin a little bit and that's why i don't use it both morning and evening. using a really good moisturizer during the day helps for the dryness and helps make up go more evenly. ### ⭐⭐⭐⭐⭐ Great item! *by D***S on 4 November 2024* Item works great with daily application and we had an exceptionally quick delivery time.
