Odd smell but good!
[I received this product in exchange for my honest review] I've been using the Sunday Riley Tidal Deep Hydration + Plumping Serum for a little while now, and I have a few thoughts to share. When I first started using it, the smell definitely caught my attention. It's not awful, but it has a bit of a...

Wanted to Love but Not for Sensitive Skin
[I received this product in exchange for my honest review] I wanted to love this product because instantly when I put it on it was light, hydrating, and glided on like a breeze. I loved how refreshed I looked really gave that glaze doughnut look which was perfect for the night routine. Unfortunate...

Love love love it!!
[I received this product in exchange for my honest review] Sunday Riley never disappoints! I love this product & I mean it! I love how pumping and hydrating it feels instantly after applying. It doesn't have a very pleasant scent but I don't mind it seeing the results. I'm going to continue using it everyday & will purchase it if I run out.

My holy grail hyaluronic acid serum!
I've been using Sunday Riley's Tidal serum for about 6 weeks now, and it's become a staple in my skincare routine — especially when my skin feels dry, tight, or dull. This isn't just your average HA serum — it has five types of hyaluronic acid, which really helps to hydrate different layers of my skin.The polyglutamic acid (yes, that's a thing) is very effective at locking in moisture — I've noticed my skin stays bouncy throughout the day. It feels like a lightweight water-gel that forms a "breathable water seal" on your skin, giving you that juicy, dewy finish without greasiness. Instead of snail mucin, this uses a plant-derived alternative — great if you want that bounce but prefer cruelty-free ingredients. I use it both morning and night. It layers nicely under moisturizer or sunscreen without pilling.It's vegan, gluten-free, and cruelty-free, which is a big plus for me. If your skin feels parched, tight, or lacks bounce, this serum is absolutely worth trying. It's one of those hydration powerhouses that doesn't feel heavy or sticky, but leaves you looking dewy and plumped. For the price, I don't use it like a "treatment" product — more like a daily hydration boost — and in that role, it's been fantastic.
Great serum
[I received this product in exchange for my honest review] This was my first time using anything from this brand, and it definitely exceeded my expectations. The packing is nice and serum is good consistency. It has sort of like a chemical smell to it but I don't notice it anymore. I'm usually very sensitive to new products, but this serum didn't irritate my skin at all. It hydrated my skin really well and left it feeling soft and healthy. Overall, I'm really happy with it and would definitely recommend it!
A tiny drop restored my moisture and improved elasticity.
During these colder months when my skin usually feels dry and dehydrated, this hydrating serum has truly brought the moisture back. My skin looks refreshed and glowy again! I also never knew that as I got older and started noticing some loose skin, a serum could actually help restore the elasticity in my face and neck, but this one really has. You only need a tiny amount because it goes a long way, and my face feels so soft and smooth after applying it. Highly recommend for anyone needing a boost of hydration and firmness this season!

A serum that perfectly hydrates and plumps
[I received this product in exchange for my honest review] This serum from Sunday Riley exceeded my expectations. The pump was easy and put out a perfect amount of product each time. My skin felt hydrated without looking heavy and greasy. I love it so much that I used it at least twice a day! I wish more came in a bottle because it's that good. The only thing that was off putting is the scent…it reminded me of grass.
