The Ordinary Hyaluronic Acid 2% + B5
A cheap, effective hydration serum that plumps dry skin beautifully — if you can tolerate the stickiness and master the damp-skin application dance.
What real owners actually say
Here's the thing about this serum: people are OBSESSED with it, but also deeply confused by it. The comment sections are essentially a support group for people who don't know when to apply it in their routine. 'After toner? Before moisturizer? On damp skin? Dry skin? Can I use it with retinol? Tretinoin? Adapalene? Microblading?' The confusion is real, and honestly, the brand could do better with instructions. That said, the people who figure it out tend to fall hard. Multiple users call it their 'favourite' Ordinary product, a staple in their night routine. Dry skin folks in particular report a noticeable glow and hydration boost. One user with seborrheic dermatitis found it significantly helpful alongside niacinamide. Oily and acne-prone skin users ask if it's safe for them — the answer from experienced users seems to be yes, but you still need a moisturizer on top. The biggest gripe? Texture. It's sticky. It leaves a film. If you apply it without following up with a cream, it can flake off hours later like you're molting. There's also anxiety about a reformulation: the new version is apparently more yellow than the old clear formula, and some users report a slight burning sensation the old one didn't have. Whether that's a formula change or a batch issue, people are spooked. But the price? Universally praised. For under $10, people are willing to forgive a lot.
What Glow loved
- Incredibly affordable — arguably the best HA serum per dollar
- Visible hydration and glow for dry skin types within days to a week
- Helps repair skin barrier after retinoids and tretinoin
- Reformulation generally perceived as an improvement by informed reviewers
- Works for oily and acne-prone skin when used correctly
What Glow didn't
- Sticky, tacky texture that bothers many users
- Flakes and leaves residue if you skip the moisturizer step
- New formula is yellowish (vs. clear old version) — some find this alarming
- Application instructions from the brand are confusing; most users learn from YouTube instead
- Some users report mild burning with the reformulated version
The YouTube reviewers who actually tried it
Across 10 YouTube reviews, the picture is surprisingly consistent: this is a solid, no-frills hydration serum that does what it says — but you HAVE to use it right. Multiple creators explicitly demo the damp-skin technique: cleanse, leave face wet, apply a few drops, then immediately seal with moisturizer. Skip that last step and you get the dreaded sticky film that flakes off. Doctor Anne, who did a proper reformulation comparison, confirmed the old version was more transparent while the new one is yellowish and slightly tackier. She also noted the stickiness personally didn't bother her as a night treatment. Scarlette Reviews called it a 'holy grail for dry skin' and praised its ability to repair the skin barrier after tretinoin — she got her mom hooked too. Mad About Skin's reformulation video generated genuine excitement in the comments, with people placing orders mid-video. On the flip side, Diba's Quest posted a literal 'Beware' short about it, though the actual issue was just incorrect application, not the product itself. One interesting detail from Shelley Nayak's viewers: some saw fewer breakouts and small bumps after just a week. But another user flatly said 'I never liked this serum' — so it's not universal love. The creators who tested both formulas generally preferred the reformulation for feel, even if the yellow tint alarmed some users at first.
The caveats nobody puts on the bottle
When user voice and video reviewers contradict each other, that's usually where the truth lives. Here's the disagreement.
- BRAND doesn't clarify application well enough, while USER comments are overwhelmingly 'how do I use this?' — the confusion is systemic, not user error.
- USER comments report the new formula is yellowish and burns slightly, while VIDEO reviewers (Mad About Skin, Doctor Anne) generally frame the reformulation as an improvement — a perception gap worth noting.
- VIDEO creators universally say 'apply to damp skin,' but USER comments reveal many people forget or didn't know — and then blame the product for flaking/stickiness.
- Multiple VIDEO reviewers say this works for all skin types including oily, but USER comments show oily/acne-prone users are anxious about breakouts and unsure whether to trust it.
- Scarlette Reviews (VIDEO) calls it a 'holy grail' for dry skin and barrier repair after tretinoin, while one USER in the same video comments said 'I never liked this serum' — results really depend on skin type and application.
- Diba's Quest (VIDEO) posted a 'Beware' thumbnail about this serum, but the actual issue was user error (application technique), not product quality — clickbait tension with genuine user enthusiasm.
