Good color, crappy pump
Color: Dark, Size: 16 Fl Oz (Pack of 1), Color: Dark, Size: 16 Fl Oz (Pack of 1)
It works! Put it in at 9 and rinsed off at 2 and the color was apparent. And I clearly need some practice applying with my mit as you can see in the photo haha! Only reason for docking is my pump won’t work. Won’t open up to pump so have to open the entire top and pour it out onto my mit which is annoying. There also is definitely a self tanning scent that is very notable so if you get this thinking there is no smell- you’d be wrong. I wouldn’t wear it out in public

Helped My Texture & Pores So Much
Size: 2.03 Fl Oz (Pack of 1)
I bought this mainly to help with skin texture and the appearance of my pores, and it has honestly worked really well. After using it consistently, my skin feels noticeably smoother and looks more refined overall.
I’ve especially noticed a difference around areas where I tend to have larger pores and uneven texture. My skin looks softer, more even, and makeup applies much more smoothly now.
The serum itself feels lightweight, absorbs nicely, and doesn’t leave my skin sticky or greasy. It layers well with the rest of my skincare routine and hasn’t irritated my sensitive skin at all.
I also love that the jumbo size lasts a long time, so it feels like a really good value for the amount you get. Definitely happy with this purchase and would repurchase again!

Surprisingly Effective – Smoother, Firmer, More Hydrated Skin!!!
Size: 1.01 Fl Oz (Pack of 1), Size: 1.01 Fl Oz (Pack of 1)
I decided to try the FRANKLY Closer Serum after seeing it listed as Amazon’s Choice and noticed it had been purchased 6K+ times in the past month and I can see why! This serum has been a great addition to my skincare routine.
The texture is lightweight and absorbs quickly, leaving no sticky residue. It feels hydrating right away, and over time, I’ve noticed my skin looks smoother and more refined, especially around my pores and T-zone. It doesn’t clog pores, which is important for my acne-prone skin, and it layers well under makeup or sunscreen.
I appreciate the powerhouse ingredients like 9 peptides, vegan collagen, adenosine, and PHA they’ve helped improve my skin’s elasticity and texture without irritation. The glow is real, and I can see that “glass skin” look starting to come through with consistent use.
The 1.01 fl oz size may seem small, but a little goes a long way. The pump bottle is hygienic and easy to use, and the overall packaging feels clean and modern.
If you’re looking for a gentle, multi-tasking anti-aging and pore-refining serum, this one is a great value and it lives up to the hype.

The best pore reducer, even on older complexions!
Size: 2.03 Fl Oz (Pack of 1)
Nothing has ever worked reducing my enlarged cheek and nose pores over the years. Now I've finally found something that works. By the second day there was noticeable results and by the end of the first week even the small wrinkles under my eyes was gone! I use it with my normal skin care routine but I won't do without this again.

Good and Hydrated
Size: 1.01 Fl Oz (Pack of 1)
It’s very good and hydrates very well. Not a fast or much improvement on pores. But very good to hydrate your skin.
