The Ordinary Hyaluronic Acid 2% + B5 (Ceramides) — Hydration Serum
What it is: A hydration-focused serum designed to deliver moisture and support the skin barrier. Features include instant hydration, ceramides for moisture retention, and a reduction in the appearance of fine lines.
Best for: Dry or very dry skin needing immediate plumpness and long-lasting hydration. Especially suitable for those who want extra barrier support through ceramides.
Why chosen: This product prioritizes hydration while reinforcing the skin’s protective barrier. It pairs well with a cream to seal in moisture and can help smooth the skin’s surface over time.
Limitations: Some users with very oily skin may find it less necessary on non-dry days; better as a daytime hydration step rather than sole treatment for extreme dryness.
The Ordinary Niacinamide 10% + Zinc 1% — Brightness & Smoothness
What it is: A lightweight, water-based serum that improves radiance and smoothness, while supporting the skin barrier and hydration.
Best for: Those with dry skin who also struggle with uneven texture or shine from oil. It helps control oil in some users while delivering hydration benefits.
Why chosen: It complements hydration serums by addressing texture and brightness, making it a good add-on for dry skin concerns that go beyond surface moisture.
Limitations: Not a primary hydrator; best used after a hydrating serum if your goal is maximum moisture retention.
The Ordinary Soothing & Barrier Support Serum
What it is: A redness-reducing, hydrating solution designed to support and repair the skin barrier, with immediate hydration boost.
Best for: Skin prone to redness, dryness, or irritation. Suitable for sensitive or inflamed skin needing quick comfort and barrier recovery.
Why chosen: A strong option for barrier repair that can be used alongside a hydrating serum to minimize dryness-related discomfort and soothe irritation.
Limitations: Claims of barrier recovery time (2 hours) may vary by individual; use as directed with a gentle routine to avoid overloading sensitive skin.
The Ordinary Lactic Acid 5% + Hyaluronic Acid 2% — Gentle Exfoliation
What it is: A mild exfoliating serum that smooths texture with lactic acid while supporting hydration with hyaluronic acid.
Best for: Dry skin seeking subtle resurfacing without harsh stripping, plus moisture retention for a refreshed appearance.
Why chosen: Combines exfoliation with hydrating acids, offering a path to brighter, smoother skin without aggressive peeling.
Limitations: Exfoliating acids can increase sun sensitivity; use sunscreen daily and avoid if you have very sensitive or reactive skin without patch testing.
The Ordinary Daily Set — Hydration Routine
What it is: A three-step daily routine including Squalane Cleanser, Hyaluronic Acid 2% + B5, and Natural Moisturizing Factors + HA.
Best for: Beginners or anyone seeking a complete hydration-focused routine that covers cleansing, moisture, and barrier support.
Why chosen: It bundles key hydrating steps, making it easier to establish a consistent routine that targets dry skin comprehensively.
Limitations: The set may include items you already own; consider purchasing individual components if you only need hydration or cleansing refreshment.
The Ordinary Alpha Arbutin 2% + Hyaluronic Acid
Note: Included for reference to brightening and hydration, though it is less focused on dry-skin hydration than the other selections.
Best for: Skin that benefits from brightness and even tone alongside hydration, not a primary hydrator.
Why chosen: Provides a complementary option when pairing hydration with targeted brightening, particularly for dry skin with pigment concerns.
Limitations: Not a primary hydration serum; pair with a dedicated hydrating serum for best moisture outcomes.
Buying Guide: Hydration-First Serums For Dry Skin
- Core hydration vs. barrier support: For very dry skin, prioritize serums that include humectants (like hyaluronic acid) and barrier-supporting ingredients (such as ceramides or barrier-support compounds). If redness or irritation is an issue, consider barrier-focused serums alongside a hydrating option.
- Layering strategy: Apply water-based hydrators first, then seal with a moisturizer. If using multiple serums, layer from thinnest to thickest texture.
- Selecting textures: Water-based hydrators work well under moisturizers for most dry skin. Gel-like formulas absorb quickly; lotion-style hydrators offer lasting moisture without heaviness.
- Patch testing: When trying a new serum, test on a small skin area for 24–48 hours to monitor for reactions, especially if you have sensitive or eczema-prone skin.
- Sun awareness with exfoliants: If incorporating exfoliating serums (like lactic acid), pair with daily sunscreen to protect newly revealed skin from sun damage.
- Combination approach: For optimal hydration, a simple routine can include a gentle cleanser, a hydrating serum (hyaluronic acid + B5 or HA with ceramides), barrier-supporting serum if needed, and a non-greasy moisturizer.

– The Ordinary Hyaluronic Acid 2% + B5 is a strong candidate for immediate hydration and ceramide-supported barrier care. - Should I use a barrier-supporting serum every day?
