Amazing serum

I’ve been using this for a few weeks, and here’s my honest review ✅ Reduces excess oil & shine ✅ Calms redness + post-acne flare-ups ✅ Layers beautifully – no pilling or sticky residue ✅ Lightweight, fast-absorbing, and fragrance-free Would I recommend it? YES — especially for oily, sensitive, or acne-prone skin. If you’re looking for a gentle niacinamide serum that keeps your skin clear and balanced without irritation, this is a solid pick.

Nice to mix with the Hyaluronic Acid serum

I've been mixing this with Hyaluronic Acid serum and I'm loving the combination and results. I feel tighter, more hydrated a little less red.

Byebye blemishes

I LOVE this product. I have super sensitive acne prone combination skin and shockingly this product clears my pimples within a few days without drying or causing eczema patches. It's pricey but it works.
