The Ordinary Hyaluronic Acid 2% + B5 (with Ceramides)
Size: 1 Fl Oz (Pack of 1)
The Ordinary’s Hyaluronic Acid 2% + B5 with added ceramides is a hydration powerhouse that delivers noticeable moisture and placid comfort to dry, dehydrated, or combination skin. Hyaluronic acid draws water into the skin’s surface layers, helping skin feel plump, soft, and smooth, while vitamin B5 supports enhanced surface hydration and recovery.
Adding ceramides is a smart touch because they help reinforce the skin barrier, locking in moisture and preventing water loss throughout the day. The result is a formula that doesn’t just sit on the surface — it helps improve the skin’s resilience over time.
The texture is lightweight and gel-like, absorbing quickly without leaving a sticky or heavy feel, making it easy to layer under serums, moisturizers, and sunscreen. It works beautifully in both morning and evening routines.
After consistent use, many users notice better overall hydration, smoother fine lines caused by dryness, and a more comfortable complexion — especially during dry seasons or in air-conditioned environments.
Pros:
✔ Deep hydration that lasts
✔ Lightweight and fast-absorbing
✔ Great paired with other products (moisturizers / creams)
✔ Ceramides help support the skin barrier
Cons:
✖ Not a direct treatment for acne or pigmentation
✖ Effects build gradually with consistent use
Overall: A very effective and versatile hydrator that’s easy to use and works well for most skin types. Particularly great if you want lasting moisture and a smoother, healthier-feeling complexion.

Amazing product - instant smoothness
Size: 1 Fl Oz (Pack of 1)
I've only had this product for the last several days, but, so far, it's AMAZING. I've tried hyaluronic products before, because everyone says that you are supposed to for moisture, but, honestly, I was always underwhelmed. They were thin and did nothing. So, despite this one having great reviews, I was not really expecting anything, but the price was right.
But this product....although liquid and clear, it's got a slight thickness to it, and spreads on very smooth. You only need a little bit to cover your entire face. Despite the slight thickness, it's not gooey or sticky at all, and it dries incredibly fast. In fact, if you don't spread it around onto your face quickly enough, it's already drying. There is no real smell to it. And, as soon as it dries onto your face, your skin feels incredibly smooth. Maybe it wouldn't if you had a significant dry skin problem to begin with, but for regular, maturing skin, it leaves skin baby smooth. And it lasts all day, and my skin looks better.
I have very sensitive skin, and most things on my face eventually make my eyes water (even gentle facial moisturizers and sunscreens), but, so far, I haven't had an issue, and, because it's been a few days already, maybe I won't. Doesn't really feel like I'm wearing anything, and isn't a problem if I want to layer it with something else. I do wash it off at night, and can tell that something is still on my face even at the end of the day because it's a little slippery when I wash it. So it has staying power.
For the price, I would definitely consider trying this product for moisturizing, and instantly smoother and softer skin.

plumping hydration with no greasiness or oiliness
Size: 1 Fl Oz (Pack of 1)
Its featherweight and melds with the skin in an instant. It plumps without any residue or "slip" on the skin. I have normal skin that tends toward slight dehydration and I use adapalene and the Ordinary 2% Salicylic acid anhydrous for my sebaceous hyperplasia. Because of the sebaceous hyperplasia and the heat and extreme humidity where I live, I cannot use anything with oils or dimethicone or anything even remotely occlusive. This serum is a great way for me to get appropriate hydration without exacerbating those enlarged oil glands or making my face sticky and oily. I dont need my face sealed, a humectant like this pulls plenty of hydration into my skin and I dont lose it to the air because of the ambient humidity. Its pretty perfect for me. It also has kept my barrier intact while alternating the adapalene and salicylic acid. Its a huge bang for the buck, I mean the price point is unbeatable.
