Hey skincare enthusiasts! 👋 As a 30-something American woman navigating the world of K-beauty, I recently tried the ISOI Blemish Care Up Serum, and here’s my honest take. If you’re considering this product or just curious about its hype, read on!

What I Loved:
1. Brightening Power: This serum does deliver on its promise to brighten the skin. After consistent use for about two weeks, I noticed my complexion looked more radiant and even. Hyperpigmentation from old acne scars faded slightly, though it’s not a miracle worker—it takes time and patience.
2. Gentle Formula: My sensitive skin can’t handle harsh ingredients like niacinamide or vitamin C, but this serum (thanks to its Bulgarian Rose Oil and arbutin) was soothing and didn’t irritate my skin at all. It’s vegan and hypoallergenic, which is a big plus for anyone with reactive skin.
3. Hydration Without Greasiness: The lightweight texture absorbs quickly, leaving my skin soft but not sticky. It layers well under makeup or sunscreen, which is perfect for my busy mornings.

What Could Be Better:
1. The Price Tag 💸: Let’s be real—this serum is pricey for the amount you get. While I love the results, it’s hard to justify repurchasing without waiting for a sale (thank you, Olive Young discounts!)
2. Fragrance: It has a floral rose scent that some might find pleasant, but it’s strong enough to be polarizing. If you’re sensitive to fragrances in skincare, you might want to test it first.
3. Slow Results on Dark Spots: While it brightens overall skin tone beautifully, fading stubborn dark spots or sun damage takes longer than expected. If you’re looking for dramatic results fast, this might not be your go-to.

Who Should Try This?
- If you’re in your 30s like me and looking for a gentle brightening serum that won’t irritate sensitive skin.
- Perfect for those with oily or combination skin types—it hydrates without clogging pores.
- Great if you prefer lightweight formulas that absorb quickly and work well under makeup.

Final Thoughts
Would I recommend it? Yes—but only if you’re willing to splurge or snag it during a sale. It’s a solid addition to a skincare routine focused on gradual brightening and hydration, especially if you have sensitive skin like mine. However, if budget is a concern, there are cheaper alternatives that might offer similar results.
Let me know if you've tried this serum or have other K-beauty favorites! ✨

Influencer14 days agoLove the smell of this serum and it soothes a lot and ofc brightens my skin impressively

Influencer6 days agoI totally get what you mean about your skin not bouncing back like it used to. I started ISOI in my early 30s too and it gave me that “oh right, I can glow” moment.
-
Influencer6 days agoI never fully clicked with vitamin C serums until this one. Most either stung or oxidized in two weeks. ISOI somehow feels… steady? Influencer6 days ago✨It’s giving “grown-up brightening” energy. Not dramatic, but smooth and clear in a way that feels earned. Influencer6 days ago@Influencer I think it’s the niacinamide + arbutin combo that works so well here. No tingling, no drama, just bright skin that looks rested.
-
Influencer6 days agoHonestly this is the one serum I can use even when my skin’s slightly irritated. Huge win. Influencer6 days agoRight?? I’ve used this over barrier creams and even post-exfoliation and it never complains.
-
Influencer6 days agoI keep repurchasing this even when I try other “hyped” glow serums. Nothing else makes my skin look this consistently soft.
-
Influencer6 days agoThe texture is underrated too. Not watery, not oily, just plush enough to feel luxe. Influencer6 days agoAlso, doesn’t oxidize in the bottle like most vitamin C serums. That alone makes it worth it.
-
Influencer6 days agoMy only gripe is the price too. But honestly? It’s the only one I’ve emptied 3 bottles of. Influencer6 days agoSame here. I’ve decided I’d rather have one product that works than five that don’t.

Influencer6 days agoWe need more vitamin C alternatives like this — gentle, stable, and actually effective. Influencer6 days agoIt’s the serum I recommend to friends who say they “don’t do actives.”
