In the daily skincare routine, many women focus on deep cleansing and daytime sun protection, often overlooking a crucial step at night: Intense Moisturization.
Especially if your bedroom frequently uses air conditioning, low temperatures, or has dry air, your skin is at serious risk of dehydration. At night, when skin temperature slightly increases and the bedroom lacks humidity, water easily evaporates from the skin, leading to dry, tight, and dull skin upon waking.
Therefore, before going to bed, applying a powerful hydrating agent like HA serum (Hyaluronic Acid) is an indispensable step to protect and nourish your skin.
HA Serum and Its Extraordinary Hydration Power
Hyaluronic Acid (HA) is a naturally occurring component in the body with exceptional water retention capabilities. One HA molecule can hold up to 1000 times its weight in water. When supplemented via serum, HA acts as a gigantic "sponge," drawing moisture deep into the epidermal layers.

Using HA serum before bed offers remarkable benefits for the skin:
1. Deep Hydration and Plumpness
HA effectively delivers and retains water, helping the skin achieve ideal moisture levels. Well-hydrated skin becomes plump, smooth, and minimizes roughness or flaking caused by dehydration.
2. Supports the Reduction of Fine Lines
Dry, dehydrated skin is a key factor that makes wrinkles and fine lines more apparent. Thanks to its strong moisturizing ability, HA indirectly fills skin cells, helping to reduce the appearance of early signs of aging, promoting a younger look.
3. Maintains Elasticity and Firmness
When the skin is sufficiently hydrated, its structure becomes healthier and more supple. Skin elasticity is improved, helping the skin feel firmer and resisting sagging.
4. Regeneration and Skin Soothing
HA serum also helps soothe irritated, red skin and effectively supports the skin's regeneration process. This is a necessary step for skin recovery after damage, such as post-acne or after professional skincare treatments.

Important Note When Using HA Serum for Maximum Effectiveness
Although HA serum is an excellent moisturizing product, if used incorrectly, it can backfire and make your skin even drier.
The golden rule when using HA is: Apply it on damp skin.
HA works by attracting moisture. It has the ability to draw moisture from the environment and from the deeper layers of the skin. If you apply HA serum to very dry skin in a dry environment (like an air-conditioned room), HA will prioritize pulling moisture from your skin's deeper dermis, which can make the outer skin feel drier and tighter.
Therefore, make sure to apply HA serum when your skin is still slightly damp after cleansing or after using a toner. This provides sufficient water for the HA to hold, creating a protective moisture barrier throughout the night.
