Tidal Deep Hydration + Plumping Serum

[This review was collected as part of a promotion.] I was excited to try this serum since it was the first Sunday Riley item I had ever tried but I was left pretty disappointed. The product has a scent to it which never works well with my skin since it’s so sensitive. The consistency feels really nice once pumped out but I couldn’t get past the scent. If your skin isn’t sensitive then this product might work well for you. When I applied the product it made my skin turn red and feel and just overly greasy. I don’t think I’ll continue to use the product just from the first reaction I had.

[This review was collected as part of a promotion.] 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!

[This review was collected as part of a promotion.] 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.

[This review was collected as part of a promotion.] 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. What I Love: • Deep, multi-layer hydration. 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. • Long-lasting plumpness. 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. • Soft, springy texture. It feels like a lightweight water-gel that forms a “breathable water seal” on your skin, giving you that juicy, dewy finish without greasiness. • Vegan “mucin” from lotus root. Instead of snail mucin, this uses a plant-derived alternative — great if you want that bounce but prefer cruelty-free ingredients. • Gentle and versatile. I use it both morning and night. It layers nicely under moisturizer or sunscreen without pilling. • Clean formula. 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.

[This review was collected as part of a promotion.] 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!
