I’ve been using the Obagi Professional-C Serum 15%, and wow, it’s been a serious upgrade for my skincare routine. I’ve tried a lot of vitamin C serums before, but this one feels different—it’s potent without being too harsh, which is perfect for my skin. The texture is really nice; it’s not greasy, and it absorbs super quickly. I like that it doesn’t leave that sticky feeling some other serums do. After about a week of using it daily, I started noticing my skin looking brighter and more even. It’s like it gave my complexion this healthy glow without being over-the-top. I’ve got combination skin, so I was worried it might make my T-zone oily or irritate the drier areas, but it’s been really balanced. No breakouts, no irritation—just smoother, more radiant skin. Plus, it layers really well under makeup and other products, so it doesn’t interfere with my routine. The 15% concentration seems like the sweet spot. It’s strong enough to make a difference but not so intense that my skin freaks out. Over time, I’ve noticed my dark spots fading, and overall, my skin just looks more refreshed and less dull. If you’re looking for a solid vitamin C serum that’ll give you real results, this one’s worth a try. It’s a bit of an investment, but considering how much brighter and smoother my skin looks, I’m really happy with it!

It is quickly absorbed into the skin, not sticky, the smell is very light and delicate. Great for every day under cream. Top among other brandss.

Super expensive and packaging is subpar since it's not the proper way to store vitamin c in order for it to be as effective as possible. Will not be repurchasing.
