I have mainly used this in my morning routine, and it seems to help wake my face up! Very little scent and I have not noticed any side effects. My face does look more hydrated and fresh afterwards.

I enjoy this serum as part of my skincare routine. It is a bit on the thick side but absorbs quickly without tackiness, and plays nicely with my other serums and moisturizer. I like that it includes caffeine that seems to wake up my face, but it is also odorless.

It tightens my face! In the morning, I will sometimes get the puffy, tired looking face. After applying this serum, I notice the puffiness isn’t quite as noticeable and my face looks more taut, especially under the chin. I love using this for a quick me up when I need to look more refreshed!

The IOPE PDRN Caffeine Shot has a thicker consistency but it absorbs pretty quickly & doesn't leave skin feeling tacky. I love how this reduces puffiness, especially around my eyes, making my face look refreshed & well rested. I've also been applying this serum during microneedling sessions, which really has a noticeable lifting & firming effect on my skin. Highly recommended.

The Caffeine Shot Face Serum is an anti-aging and hydrating serum. The bottle size is about 1oz (30ml). The texture is gel-like, and the scent is acceptable. It is easy to apply and to be absorbed. No skin irritation was noticed after. No sticky feeling on the skin.

It has no scent and feels fantastic on the skin. The serum gives the skin a nice boost of hydration and plumps up the face. The ingredient looks pretty good, and I love having niacinamide in my skincare routine. quite an underrated quality-of-life improvement to the user experience.

This serum is thick yet lightweight because it absorbs super quickly on the skin and doesn’t feel tacky. It has no scent and feels fantastic on the skin.

Adding the serum, made a huge difference. I saw a difference in the tone and tightness of my skin almost immediately. I'm 60, and I am trying to figure out how to add a picture of myself, because I am told that I look a good 15 years younger than my age. I attribute this to beginning a good skin care regiment in my early thirties. This beats every brand I've ever tried. I'm thrilled to have found it, It will be my forever skin care line.

Wow. I’m noticing amazing results after just a few days. Wow. I literally NEVER write reviews, but this has really really made a huge difference! My skin feels so smooth! It seems to tighten as well as reduce swelling.
