Discover whether hyaluronic acid works better in the morning or at night, plus expert insights on hydration and product performance from Rysun’s skincare manufacturing team.

Is It Better to Put Hyaluronic Acid on at Night or Morning?

Hyaluronic acid (HA) is one of the most universal and effective hydrating ingredients in skincare. It attracts and retains moisture, supports the skin barrier, and helps keep the complexion smooth, plump, and healthy. Because it works so well for daily hydration, many people wonder:

“Should I apply hyaluronic acid in the morning or at night?”

As a research-driven skincare manufacturer with over 10 years of formulation experience, Guangzhou Rysun Biotechnology Co., Ltd. develops hundreds of hyaluronic acid serums for global brands. Based on dermatological insights and extensive formulation testing, the answer is:

You can use hyaluronic acid both morning and night — but each time offers unique benefits.

This guide explains how timing influences hydration, skin repair, and overall product performance.

1. Using Hyaluronic Acid in the Morning

Applying hyaluronic acid in the morning helps prepare the skin for the day ahead.

Morning Benefits:

• Long-lasting daytime hydration

HA holds moisture in the skin and helps prevent water loss throughout the day.

• Creates a smooth base for makeup

It plumps the skin, reducing dry patches and dehydration lines that can affect makeup application.

• Helps defend against environmental stress

Hydrated skin has a stronger barrier function, offering better resilience against pollution and dry climates.

• Suitable for all skin types

Morning application is particularly beneficial in dry seasons or air-conditioned environments.

Best for:

• Dry or dehydrated skin
• People who wear makeup
• Sensitive skin
• Hot or dry climates

At Rysun, our HA serums are formulated to absorb quickly, leaving a lightweight, non-sticky finish — ideal for daytime use.

2. Using Hyaluronic Acid at Night

Nighttime is when the skin repairs itself, making HA especially effective before sleep.

Nighttime Benefits:

• Deep hydration during skin repair cycles

Skin’s permeability increases at night, allowing moisturizing ingredients to work more efficiently.

• Helps replenish moisture lost during the day

Exposure to sun, wind, heat, and cleansing can all dehydrate the skin — HA restores balance.

• Enhances the impact of nighttime treatments

Ingredients like retinol, peptides, and ceramides pair well with HA by reducing potential dryness or irritation.

• Promotes smoother, plumper skin by morning

Overnight hydration leads to visibly fresher, healthier-looking skin.

Best for:

• Nighttime repair routines
• Retinol or exfoliation users
• People with dry or mature skin
• Cooler or low-humidity environments

Rysun’s R&D team often incorporates multi-molecular weight HA to support both surface hydration and deep moisture retention during overnight skin repair.

3. Morning vs Night: Which Is Better?

Both are beneficial — but the best choice depends on your skin’s needs.

The most effective approach:

Use hyaluronic acid twice a day for optimal hydration and barrier strength.

This is also why many brands choose hyaluronic acid as the core ingredient in everyday, universal-use serums — something we see across hundreds of Rysun’s global OEM/ODM projects.

4. Why Hyaluronic Acid Works So Well in Both Routines

Thanks to its water-binding ability and gentle nature, HA is:

• Non-irritating
• Lightweight
• Suitable for all skin types
• Compatible with most skincare ingredients
• Effective in all climates

Our Research Institute at Rysun goes further by integrating three to five molecular sizes of HA to ensure:

• Surface hydration
• Deep-layer hydration
• Long-lasting moisture retention
• Improved elasticity

This makes HA an ingredient that works seamlessly at any time of day.
