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.

Just buy it
Size: 3.38 Fl Oz (Pack of 1)
I am not even sure I want to do this review because this might mean this product gets sold out. But I wont gate-keep. Get it. This has changed the game with my skin care. I use it twice a day and let me tell you, the compliments I get are incredible. It is not greasy at all, absorps quickly, super light weight and does not irritate my skin. My skin is glass smooth. I have bought this for everyone in my life. Male and Female. I use it, let it dry then add moisturizer or sunscreen.

Works well with others!
Size: 2.03 Fl Oz (Pack of 1)
Initially and by itself, I really didn’t see any changes to my face that made me confident with this product. But now that I have a skin routine, I think it works well! Now I like it and I see changes. But alone or with few products, I’m not sure how effective it is!
