If skincare had a hydration hero, it would be Hyaluronic Acid (HA). Lightweight, hard-working, and universally loved, HA is more than just a moisture magnet — it is one of the most effective (and gentle) ways to plump, smooth, and support your skin barrier.
At KorinMi, we do not just include Hyaluronic Acid — we layer it intelligently, using multiple molecular weights that hydrate at different depths. Here is why that matters.
What is Hyaluronic Acid?
Naturally found in your skin, Hyaluronic Acid is a sugar molecule that attracts and retains water — up to 1000 times its weight in moisture.
But not all HA is created equal. The size of the molecule affects how deeply it can go:
- High molecular weight HA sits on the surface, instantly smoothing and softening.
- Low molecular weight HA travels deeper, hydrating within skin layers for long-term bounce and resilience.
- Sodium Hyaluronate, Hydrolyzed HA, and Sodium Acetylated HA — these forms are more stable and absorb faster, especially when layered.
Where You will Find It in the KorinMi Routine
SA Ampoule Toner
Packed with 3 types of Hyaluronic Acid, this toner instantly hydrates while boosting elasticity and calming inflammation — all in a refreshing, featherlight spritz.
Fun fact: It also contains Camellia Sinensis, Centella, and Licorice Root to support sensitive skin.
AA Hydro Essence
This essence is a hydration powerhouse. Infused with five HA derivatives, amino acids, and Centella extracts, it works across multiple layers of skin to reduce redness, support barrier repair, and leave your face visibly plumper within seconds.
UV Sun Protection Essence
Yes, your sunscreen can hydrate too. Ours is formulated with multiple Hyaluronic Acids, alongside tea extracts, Chamomile, and Centella to ensure your skin stays calm, fresh, and never dry — even after long sun exposure.
Why We Layer Our HA
At KorinMi, hydration is not about a single splash of water. It is about intelligent delivery, lasting results, and ingredient synergy.
We combine Hyaluronic Acid with:
- Amino acids to enhance absorption
- Soothing agents like Centella and Licorice Root
- Peptides & antioxidants to lock in hydration and prevent oxidative stress
Because real hydration is not a topcoat — it is a treatment.
Who Should Use Hyaluronic Acid?
Everyone. But especially if your skin feels:
- Dry, dull, or tight after cleansing
- Easily irritated or red
- Oil-prone yet dehydrated underneath
- Tired from pollution, stress, or sun
Hyaluronic Acid is gentle, effective, and safe to use every day — even alongside active ingredients.
How to Make It Work Harder
- Apply to slightly damp skin (after cleansing or misting)
- Layer with barrier-supporting ingredients like peptides or ceramides
- Always seal it in with a moisturizer or sunscreen — to avoid moisture loss
Hydration Is Not a Trend. It is a Foundation.
At KorinMi, we treat hydration as the base of skin health — not just a step. That is why our formulas combine multi-molecular Hyaluronic Acid, supporting actives, and clinical formulation science to do more than moisturize.
They help your skin function better. Every day.
