Promising review: "I absolutely love this stuff! I saw a dermatologist on TikTok who raved about this product and tried it out, and it's been the most amazing stuff! It's helped my face to clear up very quickly removing all of the blemish spots and dark spots around my face. It's been one of the best products I've added to my face routine. This would be great for all ages/stages and for any weather types. It doesn't moisturize much, but that's not it's intention, and there is no scent, so I'd imagine it's great for all skin types and hypoallergenic." &#;Successful Solo

Promising review: "I bought this for my teenager to use for his acne scars, but he ended up not using it. I ran out of my Murad retinol serum, so I gave this a try. I actually like it better than the Murad! It absorbs quickly, with zero smell or irritation. As with any retinol product, be sure to wear sunscreen when you're going to be outside." &#;C. Munsterman
