Korean Hyaluronic Acid: Why Korean Serums Are Superior
Hyaluronic acid (HA) is everywhere: creams, serums, masks, makeup. But not all hyaluronic acids are created equal. Korean cosmetics have perfected the use of this ingredient in a way that most Western brands have yet to adopt.
What is hyaluronic acid?
Hyaluronic acid is a molecule that your body produces naturally. Its superpower: it can retain up to 1000 times its weight in water. It is the most powerful moisturizing ingredient available, and with age, your body produces less and less of it.
Korean innovation: multi-molecular weight
Here's the key difference. While most Western serums use single molecular weight hyaluronic acid, Korean products use multiple molecular weights in a single product:
- High molecular weight (>1000 kDa): stays on the surface, creating a protective film that prevents water loss
- Medium molecular weight (100-1000 kDa): penetrates the first layers of the epidermis
- Low molecular weight (10-100 kDa): reaches deeper layers of the skin
- Ultra-low molecular weight (<10 kDa): maximum penetration, hydration from within
A perfect example is Dr. Althea's 345 Relief Cream, which contains 4 types of hyaluronic acid to hydrate all layers of the skin.
Benefits of hyaluronic acid for the skin
- Immediate and long-lasting hydration: skin looks plump and radiant
- Reduces fine lines: fine wrinkles caused by dehydration disappear
- Improves texture: skin feels soft and smooth to the touch
- Non-comedogenic: does not clog pores. Suitable for oily skin
- Compatible with everything: you can combine it with any other active ingredient
How to use hyaluronic acid correctly
Here's a VERY common mistake many people make:
Hyaluronic acid needs moisture to work. If you apply it to completely dry skin in a dry environment, it can dehydrate your skin (it draws water from the deeper layers). The correct way:
- Wash your face
- Apply the serum to slightly damp skin (right after towel drying, when the skin still has moisture)
- Seal with a moisturizer on top
- SPF in the morning

Frequently asked questions
Does hyaluronic acid work on oily skin?
Yes, it's perfect for oily skin. It adds only water, not oil. Your skin will be hydrated without shine or clogged pores.
At what age should I start using hyaluronic acid?
From age 20. The natural production of HA begins to decrease after 25, but hydration benefits at any age.
Can I use hyaluronic acid and retinol together?
Yes, and it's an excellent combination. HA counteracts the dryness that retinol can cause. Apply retinol first, wait a few minutes, then apply HA.
