Gentle but powerful serum!
Scent: Bright Force, Size: 1.01 Fl Oz (Pack of 1)
Soo gentle, moisturizing and it works! So true to its name, its a bright force after first use! This was such a pleasant surprise to me. I did some light research on this product and was confident after reading the ingredient list that it would help my post acne hyperpigmentation and even tone concerns. Im slowly increasing use and only starting in my nighttime routine as instructed. No irritation or break outs. I use almost 2 pumps and it’s enough to easily spread out on my whole face and absorbs nicely without greasiness. It has a very mild scent but it’s barely there. I have sensitive acne prone skin and it worked for me so i would highly recommend to anyone wanting to try the benefits of higher niacinamide concentrations.

Zero stars smells like chicken bullion maybe I got a bad one
Scent: PDRN, Size: 1.01 Fl Oz (Pack of 1)
My husband even commented on the smell when he kissed me goodnight after I put this on, thinking I was crazy for thinking it smelled horrible. In the pictures online it shows it a clearish pink hue even in large puddles in their marketing. One pump of this comes out a gross cloudy salmon orange color, nothing like the picture. Maybe a bad batch?

Definitely worth a try
Scent: Red Effect Serum, Size: 1.01 Fl Oz (Pack of 1)
Absorbs well without leaving any sticky feel. I’ve noticed that my skin has better evenness and smoother texture. Starting to see less fine lines and a more hydrated and tightened complexion.
