MEDITHERAPYRetinal Skin Booster Serum 5.07 fl. oz - 100ppm Retinal Ideal for Beginner & Sensitive Skin - Advanced Retinol Serum for Face - Retinaldehyde Facial Serum for Uneven Skin Tone & Fine Lines

This is a very nice product, I would definitely repurchase. The size is generous and therefore it's a great value. It absorbs quickly and works great under moisturizer or serum. 10/10 - haven't used it long enough to discern any difference but at my age *60+* --> I think every little bit helps.

There's a lot of things to like about this retinal serum, the biggest one for me being the size. This is the largest serum I have on my shelf, it's basically the size of a toner bottle.The second is the price. Despite it being a big bottle, the serum itself is within a fairly affordable price point. If you still think it's expensive, just relish in the fact that it's size makes it worth it.3rd, the serum itself feels gentle and doesn't dry me out (though I do use a mixture of moisturizing/hydrating products.) My skin does not get irritated upon use, and I do believe it makes a difference in the look of my skin. As always, (especially since this is a retinoid) I would patch test first before applying, and then gradually build a routine for it (I use it every 4 days.)Overall I give this serum a 4.9/5. Definitely will be repurchased again when I run out....some day.

I love this retinal. It helps to speed up the process of using tretinoin and conditions the skin without causing irritation. It’s very hydrating and does not cause peeling. It’s a huge bottle that will last you for a long time. Have already repurchased. Shipping time was excellent!!

This is a great retinol serum just make sure to wear sunblock if daytime. I love the way it feels on my skin as soon as I put it on.

Love this Retinaldehyde for both my face and body! The serum is lightweight, moisturizing and absorbs well. I apply it to both face and body at night. It's a great value too with such a large bottle. Highly recommend

The first time I used this Retinal skin booster I immediately saw results my skin was glowing, hydrated, and my skin looked tighten wrinkles reduction huge game changer for me will purchase this over and over!!

I've been using it for 2 weeks and I'm seeing a good change in skin complexion

I like the scent,no skin irritation so far,I see my dark sport reduce gradually. It's worth the price, can also be used on elbows to brighten it.
