Step 1: Hydrating Serum
If the stratum corneum is dehydrated, no amount of face cream will help, as it will only lock in "dry skin," leaving it still feeling parched. High-penetration formulas like SOS Booster Zero-Second Deep Hydrating Serum are ideal for this initial step.
It's not heavy for daytime use, and you can apply a thin double layer at night for enhanced hydration. Dry skin will feel noticeably softer.
Step 2: Face Cream
After hydrating, it's essential to "seal" with a face cream. Especially in air-conditioned environments or dry autumn/winter winds in Hong Kong, moisture can evaporate quickly, making moisture retention crucial.
SOS Booster Moisture-Locking Cream is a nourishing yet non-comedogenic option suitable for dry/sensitive skin.

Step 3: Mask
As for masks, consider them for "intensive care."
You don't need to use them daily, but when your skin is:
- Extremely dry and flaking
- Dull after late nights
- Unstable with seasonal redness
Nourishing masks like the Plumping Cream Mask, which has a cream-like texture, offer more lasting hydration than sheet masks.
Dry Skin FAQ
Q1: Can dry skin use masks daily? ▸
Generally, daily use is not recommended as it can thin the stratum corneum and make skin more sensitive. It's suggested to use masks 2-3 times a week; for extreme dryness or seasonal emergencies, you can use them consecutively for 1-2 nights, followed by a face cream to lock in moisture.
Q2: How much serum should I apply? ▸
Dry skin doesn't need a lot; typically, 2-3 drops are enough for the entire face. The key is even application and gentle patting for absorption, which is more effective than applying a thick layer.
Q3: Should dry skin use serum morning and night? ▸
It's best to use it twice a day, especially in autumn/winter or if working long hours in air-conditioned rooms. A thin layer in the morning for quick hydration, and a thicker or double layer at night for enhanced repair.
Q4: How to rescue dry skin during seasonal changes? ▸
Q5: What to do if makeup always cakes on dry skin? ▸
This usually indicates dehydrated stratum corneum or insufficient moisture retention. Use appropriate
