Review: Phenomenal for dry, mature skin - I'm 53 and I do have an excellent skincare regime and I mainly have very fine lines when I smile. However, due to I'll health my skin is always very dehydrated and I've tried so many products to help with no joy. I found this product on Instagram for not only helping with hydration, but also the Korean glass skin look. The gent using it had immaculate perfect skin, but with zero products he looked dry and flakey in patches. I'm still using my regular skincare, but before moisturiser, I use this. This results are incredible! Immediately after applying my skin looks plumper, hydrated and fine lines and pores blurred. My other products apply on top beautifully, zero pilling. Even my son noticed my skin looked great. I really don't know why I've not heard of this before now. It's exactly what I've been looking for, giving me the confidence I'd lost and allows for my makeup to sit and look so much better. I strongly recommend and suggest you try this. Anyone will benefit from it. Its not oily or thick and perfect on sensitive skin like mine. This is without a doubt an essential daily product for my skincare, morning and evening. Also, phenomenal to mix a pea sized amount to your foundation for a flawless look without it settling in fine lines or sticking to dry skin. Thanks for reading and I hope my wee review has helped. Keep smiling 😁
Review: Deep Hydration and Smooth Skin – A Must-Have Serum - I've been using The INKEY List Polyglutamic Acid Serum for a few weeks now, and I'm thoroughly impressed. This serum delivers intense hydration, leaving my skin feeling plump and smooth. It's lightweight, absorbs quickly, and doesn't leave any sticky residue. I've noticed a visible improvement in the texture of my skin, and it provides a great base for makeup application. Highly recommend for anyone looking to boost their skin's moisture levels!

## Questions & Answers

**Q: Does anyone who is using this think it smells awful, like chemicals? Not sure if I have a bad one or if that’s normal, it’s putting me off it!**
A: I almost didn't purchase because of this so called "smell" i kept reading about, but honestly my one barely has a scent. Scale of 1 to 10 on scent it's about 2. It may be that the scent has been changed but i definitely didn't smell anything weird.

### ⭐⭐⭐⭐ Good value serum for glowy skin

This serum is good value and pretty effective. If used before bed my skin looks great in the morning. I love the texture but it has a slightly off putting scent.
