What We Loved
- Fermented black rice brightens and evens skin tone
- 5-type HA delivers deep multi-layer hydration
- Antioxidants protect against environmental damage
- Skin feels noticeably softer after first use
- No alcohol, no fragrance, no parabens
- Vegan and cruelty-free
What We Didn't Love
- 30ml bottle is small for the price
- Brightening is gradual — takes weeks to show
- Not the most affordable option in the HA serum category
How to Use
Apply 2–3 drops after toner on slightly damp skin. Pat gently and follow with moisturizer. Use morning and evening for best results.
How It Compares
- Torriden DIVE-IN Serum ($20): Both are excellent HA serums. Torriden is purely focused on hydration; Haruharu adds brightening benefits from black rice. Use Haruharu if you want hydration + glow.
- Goodal Green Tangerine Vitamin C Serum ($29): Both target brightening but through different mechanisms. Layer Haruharu first, then Goodal for combined hydration + vitamin C brightening.
- COSRX Snail Mucin Essence ($25): Snail mucin repairs; black rice brightens. Both are worth having — alternate AM/PM.
