Why The Ordinary Became A Skincare Favourite

The Ordinary became popular because it made skincare more understandable. Instead of using complicated names, the brand clearly showed the key ingredients and their concentrations on the product label.

This helped customers choose products based on their skin concerns, such as dryness, dullness, oiliness, uneven texture, or visible pores.

For many skincare beginners, The Ordinary became the starting point for building a simple active-based routine. Products like Hyaluronic Acid 2% + B5 and Niacinamide 10% + Zinc 1% are still among the most searched and recommended formulas from the brand.

The Ordinary Hyaluronic Acid 2% + B5

Best for: Hydration, dryness, plump-looking skin, and skin barrier support.

Hyaluronic acid is a moisture-binding ingredient that helps the skin hold water. If your skin often feels tight, dry, or dull, this serum can help add hydration and leave the skin looking smoother and fresher.

The Ordinary Hyaluronic Acid 2% + B5 is designed to support multi-level hydration. It helps improve the look of dry skin and gives the face a softer, more supple appearance.

Key Benefits

• Helps hydrate dry and dehydrated skin
• Makes skin look plumper and smoother
• Supports a healthier-looking skin barrier
• Helps reduce the appearance of dryness-related fine lines
• Lightweight and easy to layer with other skincare products

How To Use

Apply a few drops to clean, slightly damp skin. Gently spread it across the face and neck. Follow with a moisturiser to lock in the hydration.

For daytime use, finish your routine with sunscreen.

The Ordinary Niacinamide 10% + Zinc 1%

Best for: Oily skin, visible pores, uneven texture, and blemish-prone skin.

Niacinamide, also known as vitamin B3, is one of the most popular skincare ingredients for balancing the skin. It helps improve the look of uneven tone, dullness, visible pores, and excess oil.

The Ordinary Niacinamide 10% + Zinc 1% is a lightweight water-based serum. It is especially popular among people with oily, combination, or blemish-prone skin.

Key Benefits

• Helps control the look of excess oil
• Improves uneven skin texture
• Reduces the appearance of enlarged pores
• Supports a clearer-looking complexion
• Helps strengthen the skin barrier
• Gives the skin a more balanced, fresh appearance

How To Use

After cleansing, apply a few drops to the face and neck. Use it before heavier creams or oils. Follow with a moisturiser.

If using in the morning, always apply sunscreen as the final step.

Can You Use Hyaluronic Acid And Niacinamide Together?

Yes, hyaluronic acid and niacinamide can be used together in the same skincare routine.

A good order is:

1. Cleanser
2. Hyaluronic Acid 2% + B5
3. Niacinamide 10% + Zinc 1%
4. Moisturiser
5. Sunscreen in the morning

Hyaluronic acid helps bring hydration into the skin, while niacinamide helps balance oil and improve texture. This makes them a strong combination for a simple everyday routine.

What Should You Avoid Mixing With Niacinamide?

Niacinamide is generally easy to use, but if your skin is sensitive, avoid layering too many active ingredients at once.

Be careful when combining it with strong exfoliating acids such as AHAs and BHAs, especially if you are new to active skincare. Using too many strong products together can lead to dryness, redness, or irritation.

A simple routine is often better than a complicated one.

Tips For Better Results

Always apply serums to clean skin. Use hyaluronic acid on slightly damp skin for better hydration. Do not skip moisturiser, because it helps seal in the benefits of your serum.

During the day, sunscreen is essential. Active ingredients can support your skin, but sunscreen protects your skin from UV damage, dark spots, and premature ageing.

Also, store your serums in a cool, dry place away from direct sunlight.

Final Thoughts

The Ordinary Hyaluronic Acid 2% + B5 and Niacinamide 10% + Zinc 1% continue to be popular because they are simple, effective, and easy to understand.

If your skin feels dry or dehydrated, hyaluronic acid is a great place to start. If your skin feels oily, textured, or congested, niacinamide may be a better fit. For many people, using both together can create a balanced routine that supports hydration, clarity, and a healthier-looking skin barrier.
