Key Takeaways
If you want hydration that feels light, fresh, and makeup-friendly, this is one of my go-to serums. The INNISFREE Green Tea Seed Hyaluronic Serum gives me that bouncy, hydrated look without the sticky film that ruins foundation. I'd rate it an 8.5/10, especially for oily skin in a hot, humid climate. For nights when your pores need a reset, pairing this with the INNISFREE Super Volcanic Pore Clay Mask once or twice a week helps balance hydration with oil control.

What It Is
This is a hydrating serum built around hyaluronic acid + humectants with a green tea angle. The vibe is simple: add water to the skin, make it feel comfortable, and keep the surface looking smooth. Think of it as a "makeup base hydration" step, not a heavy-duty barrier cream replacement.
Why I Like It (The Texture Is the Main Character)
The texture is honestly the reason this serum stays in my rotation. It feels silky and lightweight, absorbs fast, and does not leave that tacky layer that makes sunscreen pill. On oily skin that's everything.
- Not sticky: I can apply sunscreen and start makeup without feeling like my base will slide.
- Sinks in quickly: I don't need to wait 10 minutes before the next step.
- Plumps without grease: It hydrates, but it doesn't make me shiny in the T-zone.
My Real-Life Results
This serum gives me a healthier-looking surface. Less tightness, smoother texture, and my makeup sits nicer. It's not a dramatic "new skin" product. It's more like: your face looks calmer and more hydrated, so everything you apply on top behaves better.
Under makeup
This is where it wins. I can use it as a hydration layer, then go straight into sunscreen and base makeup. It's one of the few HA serums that doesn't make my foundation separate when the weather is gross.
On bare skin
On no-makeup days, it gives a soft glow and that "hydrated but clean" feeling. If I'm having a dehydrated-oily moment, it helps my skin look less tired.
Who This Is Best For
- Oily skin: especially if you want hydration without heaviness.
- Humidity life: lightweight layers that don't feel suffocating.
- Makeup wearers: if you want smoother base makeup and less pilling. To complete your oily-skin makeup routine, pair this with the INNISFREE No-Sebum Mineral Powder for excellent oil control.
- Dehydrated-oily skin: when your skin is oily but still feels tight.
Who Should Skip (Or At Least Adjust)
If you use strong retinoids (especially if you've recently increased your strength or frequency) and your skin is dry, peeling, or stinging, this serum is usually not enough on its own.
It can still be a nice hydration layer, but you'll want a proper moisturizer on top, and you can't treat this as your "barrier fix." If your barrier is compromised, go gentler and focus on comfort first. For more context on how this serum fits into INNISFREE's product range, check out my full brand guide.
How I Use It (My Routine)
I keep it simple. This is my "hydration before everything" step. If you want the full technique for HA, read my guide: how to use hyaluronic acid.
AM (makeup days)
- Cleanse (or rinse if I'm not oily).
- 1–2 pumps of serum, press into slightly damp skin.
- Sunscreen (always). Wait a minute.
- Makeup.
PM (simple hydration night)
- Cleanse.
- Serum on slightly damp skin.
- Moisturizer to seal it in (especially if you use actives).
Do You Still Need Moisturizer and Sunscreen?
Yes. Hyaluronic serums are hydration support, not the full routine. I still use a moisturizer when I need extra comfort, and I always wear sunscreen in the morning. This serum makes my skin feel nicer, but it does not replace SPF.
What I Love
- Great texture and finish
- Zero sticky feeling on me
- Works beautifully under sunscreen and makeup
- Hydrates without feeling heavy
- Easy to fit into almost any routine
What Could Be Better
- If you're on strong retinoids, you'll need more barrier support on top
- It's hydration, not a "fix everything" serum
- If your skin is very dry, it may feel too light by itself
Final Verdict: 8.5/10
I love this serum for what it is: a non-sticky, makeup-prep hydration layer that works for oily skin. If your skin is currently getting bullied by a strong retinoid, treat this as a supporting step, not the whole solution. Hydration + moisturizer + sunscreen is still the holy trio.

Frequently Asked Questions
Is INNISFREE Green Tea Seed Hyaluronic Serum good for oily skin?
Yes. On my oily skin it gives hydration without feeling sticky or heavy. It's one of my favorite "prep" serums before sunscreen and makeup.
Can I use it with retinol?
You can, but if you're on a strong retinoid and you're peeling or feeling dry, this serum alone won't be enough. Use a richer moisturizer on top and keep sunscreen non-negotiable in the morning.
Do I still need moisturizer and sunscreen?
Yes. This serum is a hydration step. I still seal it with moisturizer when needed, and I always wear sunscreen in the morning. If you want a cream-texture moisturizer that pairs well with this serum, my INNISFREE Green Tea Seed Hyaluronic Cream review covers the matching moisturizer option.
Will it pill under makeup?
It's one of the least pilling HA serums I've used. Use 1–2 pumps, press it in, wait a minute, then apply sunscreen and your base.
What's the best way to use hyaluronic acid products like this?
Apply on slightly damp skin, then seal with moisturizer. For the full routine and common mistakes, see: how to use hyaluronic acid.
Is hyaluronic acid good for oily skin?
Yes. Hyaluronic acid is one of the best ingredients for oily skin because it provides hydration without adding oil or heaviness. This serum works perfectly for my oily skin. If you want to understand why HA is so good for oily skin types, read my full guide: is hyaluronic acid good for oily skin.
