There are few skincare brands that have disrupted the beauty industry quite like The Ordinary. When it launched back in 2016, it completely changed the conversation around skincare, putting ingredients—not marketing buzzwords—front and centre. Suddenly, shoppers were discussing niacinamide, retinol and glycolic acid in the same way they might talk about a new lipstick launch, and perhaps most impressively, we could buy these ingredients for a fraction of the price of many competitors.
The brand's affordability is no accident. Rather than investing heavily in elaborate packaging, complex formulations or lengthy ingredient lists, The Ordinary focuses on tried-and-tested actives, straightforward formulations and simple clinical-looking bottles. By stripping away many of the extras, the brand is able to offer effective skincare at prices that still feel refreshingly accessible, even in today's beauty landscape.
I remember being introduced to The Ordinary right before it launched. A friend who worked in PR told me that DECIEM—the company behind one of my favourite skincare brands, NIOD—was about to release something that would shake up the industry. At the time, it sounded ambitious, but it's fair to say that she wasn't wrong. What followed was one of the most influential beauty launches of the last decade.
Since then, The Ordinary has become a permanent fixture in my skincare collection. While the brand initially built its reputation on ingredient-led facial skincare, its range has expanded significantly over the years to include everything from cleansers and moisturisers to bodycare and haircare. With so many products now available, it can be difficult to know where to start—or which formulas are genuinely worth adding to your routine.
As someone who has tested skincare for a living and used The Ordinary products for almost a decade, I've worked my way through a significant portion of the range. Below, you'll find the products I continue to recommend, repurchase and reach for most often.
The Best The Ordinary Products
- Best Overall: The Ordinary Azelaic Acid Suspension 10%
- Best Cleanser: The Ordinary Squalane Cleanser
- Best Toner: The Ordinary Saccharomyces Ferment 30% Milky Toner
- Best Serum: The Ordinary Multi-Peptide + Copper Peptides 1% Serum
- Best Moisturiser: The Ordinary Natural Moisturising Factors + HA
1. The Ordinary Azelaic Acid Suspension 10%
Key Ingredients: Azelaic acid, dimethicone, tocopherol (vitamin E)
Azelaic acid remains one of the most underrated skincare ingredients in my opinion, and The Ordinary's Azelaic Acid Suspension 10% is one of the most affordable ways to add it to your routine. The creamy treatment helps to visibly brighten dull skin, reduce the appearance of post-breakout marks, and improve overall skin tone without the irritation that can sometimes accompany stronger acids or retinoids. I particularly like recommending this to those dealing with redness, uneven pigmentation, or persistent blemish marks, as it manages to tackle multiple concerns at once. The silicone-rich texture can feel a little unusual initially, but it layers surprisingly well after lighter serums and before moisturiser.
Pros
- Helps fade post-inflammatory pigmentation and acne marks
- Brightens skin tone and boosts radiance
- Suitable for sensitive and redness-prone skin
- Affordable price point
Cons
- Silicone-heavy texture isn't for everyone
- Some users may find the finish slightly mattifying
2. The Ordinary Squalane Cleanser
Key Ingredients: Squalane, glycerin
If you're someone who finds that many cleansers leave your skin feeling tight or stripped, this is well worth trying. The creamy balm-to-oil formula melts away makeup, sunscreen, and daily grime while maintaining the skin barrier, making it particularly well-suited to dry, sensitive, and dehydrated skin types. Unlike many first cleansers, it rinses away easily without leaving behind a greasy residue, and the minimalist formula means it's unlikely to overwhelm reactive skin. It's one of those basic-in-a-good-way products that does its job exceptionally well without a lot of fanfare.
Pros
- Removes makeup and SPF effectively
- Gentle enough for sensitive skin
- Fragrance-free
Cons
- May require a second cleanse for heavier makeup
3. The Ordinary Saccharomyces Fermer 30% Milky Toner
Key Ingredients: Saccharomyces ferment (30%), N-acetylglucosamine (NAG), squalane
One of the newer additions to The Ordinary's line-up, this milky toner feels much more premium than its price tag suggests. Formulated with a high concentration of saccharomyces ferment, it works to boost radiance, support hydration, and smooth the look of uneven texture. What I love most is that it delivers a gentle exfoliating effect without relying on traditional acids, making it a great option for those who find stronger exfoliants too aggressive.
Pros
- Leaves skin looking brighter and more radiant
- Suitable for sensitive skin
- Helps improve skin texture over time
Cons
- Results are more gradual than stronger exfoliating acids
4. The Ordinary Multi-Peptide + Copper Peptides 1% Serum
Key Ingredients: Copper peptides (1%), Matrixyl 3000, Matrixyl Synthe'6, Argirelox peptide complex, amino acids, hyaluronic acid
If I had to choose one product that demonstrates just how far The Ordinary has come since its early single-ingredient days, it would be this serum. Formerly known as Buffet + Copper Peptides, it's packed with an impressive blend of peptides, amino acids and hydration-boosting ingredients designed to support skin health and target multiple signs of ageing at once. The lightweight texture sinks in quickly, making it easy to slot into almost any routine, while the distinctive blue hue comes from the copper peptides themselves. It's one of the more expensive products in the range, but compared to many peptide serums on the market, it's incredibly good value.
Pros
- Targets multiple concerns including fine lines, firmness, and breakouts
- Lightweight, easy-to-layer texture
- Skin appears smoother and healthier with consistent use
- Affordable price point compared to other peptide serums
Cons
- One of the pricier products in The Ordinary range
- Results can take several weeks to become noticeable
5. The Ordinary Natural Moisturising Factors + HA
Key Ingredients: Natural moisturising factors, hyaluronic acid, amino acids, fatty acids, urea, ceramide precursors
This is one of those moisturisers that does exactly what it promises to do—no more, no less. Rather than relying on trendy ingredients or a luxurious texture, it focuses on replenishing the components naturally found within healthy skin to support hydration and barrier function. The result is a straightforward, dependable moisturiser that works well for most skin types and layers beautifully with active ingredients. Whenever someone's skincare routine feels overly complicated or their skin barrier is feeling compromised, this is often one of the first products I suggest.
Pros
- Supports hydration without feeling heavy
- Fragrance-free and suitable for sensitive skin
- Works well alongside active ingredients
- Affordable price point
Cons
- Functional rather than luxurious
- Some very dry skin types may prefer a richer cream
- Can feel slightly matte on the skin
6. The Ordinary 100% Plant-Derived Squalane
Key Ingredients: 100% plant-derived squalane
If you're nervous about facial oils, this is a fantastic place to start. Squalane is naturally present within the skin, which means it's generally well tolerated across a wide range of skin types, including oily and breakout-prone complexions. Unlike heavier oils, it feels lightweight and silky, helping to lock in hydration and soften the skin without leaving an overly greasy finish or clogging pores. I particularly love mixing a few drops into moisturiser during the colder months or pressing it onto skin as the final step of an evening routine.
Pros
- Lightweight and non-greasy compared to many facial oils
- Helps reduce dehydration and improve softness
- Suitable for most skin types
Cons
- Doesn't provide active benefits beyond moisturising
- Some users prefer a richer oil texture
7. The Ordinary Caffeine Solution 5% + EGCG
Key Ingredients: Caffeine, epigallocatechin gallatyl glucoside (EGCG)
Few eye products have achieved quite the cult status of this one. Designed specifically to target puffiness and tired-looking eyes, the lightweight serum combines caffeine with antioxidant-rich EGCG derived from green tea leaves. While it won't magically erase dark circles caused by genetics, I have found it particularly useful for reducing morning puffiness and making my eye area look more awake. The watery texture absorbs quickly and layers easily underneath concealer without causing pilling.
Pros
- Helps reduce the appearance of puffiness
- Affordable price point
- A little goes a long way
Cons
- Less effective for hereditary dark circles
- Results are subtle rather than dramatic
8. The Ordinary Hyaluronic Acid 2% + B5
Key Ingredients: Hyaluronic acid, vitamin B5 (panthenol), ceramides
Hydrating serums don't need to be complicated, and this formula proves exactly that. Combining multiple forms of hyaluronic acid with barrier-supporting ingredients, it helps draw water into the skin and improve overall hydration levels. The latest version of the formula is significantly more elegant than earlier iterations, with a smoother texture that feels less sticky and layers more comfortably under moisturiser. If your skin often feels tight, dehydrated, or lacking in bounce, this is an easy and affordable addition to your routine.
Pros
- Provides noticeable hydration
- Affordable price point
- Suitable for most skin types
Cons
- Functions best when applied to damp skin
- Requires a moisturiser on top to lock in hydration
9. The Ordinary Niacinamide 10% + Zinc 1%
Key Ingredients: Niacinamide, zinc PCA
Arguably The Ordinary's most famous product, this serum introduced countless people to niacinamide and quickly became a skincare staple for those dealing with excess oil and breakouts. Niacinamide is a brilliant all-rounder ingredient, helping to reduce the appearance of enlarged pores, regulate oil production and support a healthier skin barrier, whilst zinc helps to minimise excess shine. It's one of the products I most frequently recommend to those struggling with congestion or recurring blemishes, particularly if they find harsher acne treatments too drying. Despite its popularity, it's worth remembering that consistency is key—this is a product that tends to deliver its best results over time rather than overnight.
Pros
- Helps reduce excess oil and shine
- Can improve the appearance of enlarged pores
- Affordable price point
Cons
- Can pill when layered with certain products
- Results may take several weeks to become noticeable
