The Ordinary Hyaluronic Acid 2% + B5 — Multi-Depth Hydration

The Hyaluronic Acid 2% + B5 serum from The Ordinary delivers immediate, long-lasting hydration for smoother, plumper skin. Ceramides in the formulation help lock in moisture and reinforce the skin’s protective barrier, which is especially important for dry or sensitive complexions. The product also targets fine lines, supporting elasticity and a more hydrated appearance.
The Ordinary Soothing & Barrier Support Serum

This serum targets barrier recovery and redness, making it suitable for irritated, dry skin. It is noted for repairing and strengthening the skin barrier within a short timeframe and delivering a hydration boost that helps moisture last throughout the day. The formula has gained acceptance for sensitive or eczema-prone skin, aiding comfort and resilience.
The Ordinary Natural Moisturizing Factors + Hyaluronic Acid

This lightweight hydrator provides non-greasy moisture with skin-identical ingredients such as amino acids, fatty acids, ceramides, urea, and hyaluronic acid. It supports the skin’s natural hydration barrier, making it a practical daily option for those with dry, sensitive, or barrier-compromised skin.
The Ordinary The Daily Set

This three-step routine combines Squalane Cleanser, Hyaluronic Acid 2% + B5, and Natural Moisturizing Factors + HA. The set is designed to cleanse gently, hydrate deeply, and seal moisture for a complete daily regimen that supports skin hydration and barrier function.
The Ordinary Serum Favorites Set

The Serum Favorites Set bundles several daytime serums including options that hydrate, brighten, and refine skin texture. The included Hyaluronic Acid, Niacinamide-based products, and hydration-focused formulas provide a well-rounded approach for dry or uneven skin, enabling customization while maintaining simplicity.
Buying Guide: Key Purchase Considerations For Dry Skin
- Hydration first: Look for humectants like hyaluronic acid in combination with ceramides or other barrier-supporting ingredients to lock moisture in and fortify the skin’s protective barrier.
- Barrier restoration: Serums labeled as barrier-support or barrier-repair can help reduce irritation and redness, improving comfort during dry periods.
- Lightweight vs. heavier textures: For oily-dry combinations, lightweight hydrators with humectants can prevent a greasy feel, while richer formulations may be better for extremely dry or mature skin.
- Active ingredients: Niacinamide can support brightness and texture, but for dryness prioritize humectants, ceramides, amino acids, and barrier-support ingredients. Avoid potentially irritating fragrances if you have sensitive skin.
- Patch testing and tolerance: Start with a small amount, especially with barrier-focused serums, to gauge reaction and ensure hydration is achieved without irritation.
- Regimen integration: Pair serums with a gentle cleanser and a supporting moisturizer to maximize barrier protection and moisture retention.
- Price and value: Sets can offer a cost-effective way to sample multiple formulas, yet verify that every product aligns with your specific dryness concerns before purchase.
- Safety and suitability: For sensitive or eczema-prone skin, prioritize products with barrier-support claims and check clinical or dermatologist recommendations where possible.
In summary, selecting the right Ordinary serum for dry skin involves prioritizing hydration, barrier support, and a lightweight, non-irritating formula. The products above offer varied approaches—from direct hydration with hyaluronic acid and ceramides to barrier-repair serums and routine sets—that can be mixed and matched to fit daily skincare needs without overwhelming the skin.
