SUNDAY RILEY TIDAL Deep Hydration & Plumping Serum

This serum is…okay. Its decently hydrating and goes on nice and smooth, but it smells weird (a cross between seaweed and a doctor's office) and it hasn't really made any noticeable difference in the appearance or feel of my skin. I'll use up the rest of my bottle but I won't be purchasing again.

[I received this product in exchange for my honest review] This product is great and very hydrating especially in the cold dry winter weather! It has been a game changer and I would definitely recommend to anyone with dry acne prone skin! It absorbs very nicely into the skin and leaves you looking very hydrated without being heavy. The only downfall is the smell. It's not overpowering it's kind of like play dough, which isn't my favorite. Great product and I love the pump!

I am an avid user of Sunday Riley products. I loved the old tidal moisturizer when it was out. I bought this as I was excited about the name returning. I put this on in the morning, and hours later my entire face and neck broke out in itchy hives. nothing else in my routine had changed at all, except using this serum. not sure genuinely how many stars to give or not give (I settled on two because having hives at work isn't my idea of fun?) but just wanted to share my experience in the event this happens to others!

[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.

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.
