Created using AI; curated by Glow Protocol. AI tools support research, product comparisons and writing. Our recommendations are editorial selections. How we work.
Quick answer
The most useful Ordinary product is the one that fills a real gap in your routine. Start with a moisturiser if you need hydration; consider one targeted serum for a specific concern. High-strength retinol, copper peptides and vitamin C are optional choices with different restrictions. This ranking reflects buying priorities, not a head-to-head product test or a list everyone should own.
How we curated this: current manufacturer formulas and instructions, relevant dermatology guidance and the research linked below. Glow Protocol has not tested these products or medically reviewed this article. Formula checks updated 27 September 2026.
The Ordinary products ranked by buying priority
Our order prioritises a missing basic first, then a defined concern, then more demanding optional formulas. It is an editorial decision based on role, application burden and compatibility. Skin type and what you already own matter more than the number in a list.
| Product | Reason to consider it | Reason to pause |
|---|---|---|
| NMF + HA | A missing daily moisturiser | You already have one you like, or need a richer texture |
| Niacinamide 10% + Zinc 1% | Visible shine and uneven texture | Duplication or poor tolerance of this serum |
| Azelaic Acid Suspension 10% | Uneven-looking tone and texture | You need medical treatment or dislike a silicone-based suspension |
| Alpha Arbutin 2% + HA | An optional dark-spot serum | You expect melasma prevention or a guaranteed result |
| Retinol 1% in Squalane | A higher-strength option for an established retinol user | You are starting retinol or have irritated skin |
| Vitamin C Suspension 23% + HA Spheres 2% | A water-free direct vitamin C formula | You want a smooth watery serum or dislike tingling |
| Multi-Peptide + Copper Peptides 1% | An optional peptide step | Its compatibility restrictions complicate your routine |
1. Fill a basic gap before buying more actives
Natural Moisturizing Factors + HA: the straightforward hydration choice
The current manufacturer ingredient list includes several humectants and emollients. This is the original NMF + HA cream, not NMF + PhytoCeramides or the lighter Beta Glucan version. That distinction matters when comparing listings.
Use after serums according to the directions. If this texture leaves you uncomfortable, choosing a richer moisturiser can be more useful than adding several hydrating serums. A ceramide moisturiser comparison can help you consider other formulas.
Niacinamide 10% + Zinc 1%: an optional targeted serum
The brand positions this water-based serum for shine, congestion and uneven-looking texture. Its directions place a few drops before heavier products, morning and evening. The brand recommends using its vitamin C products in a separate routine.
A 12-week split-face trial in 50 women found improvements with a 5% niacinamide formula compared with its vehicle. It did not test this 10% serum or establish that doubling the concentration doubles the benefit. If niacinamide is already in your moisturiser, a separate serum may be unnecessary.
2. Pick one product for a defined concern
3. Compare the more demanding optional formulas
What you can skip without missing an essential
A second hydration serum: optional if your moisturiser already keeps your skin comfortable. Hyaluronic acid is not automatically unsuitable in dry weather; judge the complete formula and how your skin responds.
A strong peel as a beginner purchase: The Ordinary labels its AHA 30% + BHA 2% Peeling Solution for experienced acid users and says not to use it on sensitive, peeling or compromised skin. You do not need to graduate to it because you turned 30.
An expensive upgrade on a timer: there is no need to leave an affordable brand after six months. Change a product when its texture, tolerance, availability or results no longer meet your needs. More spending does not establish better performance.
Before buying on Amazon
- Match the exact name and concentration, especially 1% versus 0.5% retinol and copper peptides versus the non-copper serum.
- Compare the selected volume, pack quantity, seller, delivery cost and return terms. Search results can land on a different size or bundle.
- Check the current box against the manufacturer instructions. Formulas can vary by region or change over time.
- Buy one addition at a time. A good price on an incompatible or unnecessary product is still wasted spending.
For application order, use our separate The Ordinary routine guide alongside the current product labels. This page helps you select a product; it does not prescribe a seven-product routine.
Common questions
Which Ordinary product should I buy first?
If you lack a comfortable moisturiser, start there. If your basics already work, choose one product for a concern that matters to you, or buy nothing extra. Niacinamide and retinol are not compulsory purchases for everyone over 30.
Can I use all seven together?
No. Several of these formulas have manufacturer pairing restrictions. Plan around the exact labels, rather than assuming that separate layers or a short waiting period make them compatible.
Is 1% retinol a good beginner choice?
It is a high-strength option. The AAD advises starting with a low-intensity retinoid, and The Ordinary recommends starting lower in its range. Retinoids should not be used during pregnancy.
Are the cheapest listings always the best value?
No. A smaller bottle, a different strength, a multipack or delivery costs can change the comparison. Choose the correct product and a seller you are comfortable buying from before comparing the total cost.
Sources and editorial limits
Sources checked 27 September 2026. The seven manufacturer pages linked beside each product support formula identity and directions. They are commercial sources, not independent proof that a product outperforms alternatives. The niacinamide trial used a different 5% formula; ingredient studies do not establish results for every retail serum.

- The Ordinary: layering guide. Exact product directions take priority.
