GOODAL Green Tangerine Vitamin C Serum - Advanced Version (2.02 Fl Oz (Pack of 2, Refill Included))

I have been using this serum for years and it helps keep my spots at bay. It’s lightweight and absorbent. Not sticky at all. Darker spots need more time to lighten but overall, it works! I love that they sell refills!

This is really good vitamin c serum. It dries sticky and absorbs fast. I love the gentle tangerine smell too. I would definitely order this again.

I absolutely love this product. I found it originally while I was visiting Seoul and thought I would give it try. It has lightened sunspots and my skin feels fabulous. I recommend this product to all my friends and family.

This is one of my favorite products. It’s affordable, and after using it for a few months, my dark spots have lightened. It’s gentle, fragrance-free, and makes my skin feel hydrated without any tightness.

This is a well-known product and is either loved or hated depending on what people experience with this. I noticed from various forums and groups, a lot of people find that it's not super effective, and some complain of irritation and additional pimples, but I didn't experience the latter. The serum seems to be a very mild form that doesn't have any actives we're used to in the western world. There's no ascorbic acid or its derivatives, and it's mainly some citrus ingredients that are supposed to act as vitamin C. I've tried some products like this before, and I noticed even though they were mildly effective, they still can't compare to proper ascorbic acid vitamins C serums. But it's not to say that people shouldn't use it. If it works for you and l doesn't cause irritation, then it is a great beginner product to gently ease into using vitamin C. And then you can either switch to a proper ascorbic acid containing product, or just find something that is stronger and mentions a percentage in the ingredients. With this you don't know how much you're getting, but at the same time it's not a totally useless product in my opinion. If you have sensitive skin, try to start using it only once every 2 or 3 days to see how you react, and if you're tolerating it fine, you can switch to daily use. Vitamin C is best used in the morning after your cleanser and toner, and before moisturizers. Definitely follow up with sunscreen for the best results for your skin. Also worth mentioning that it does have a somewhat strong artificial smell that doesn't linger for too long, thankfully. And worse comes to worst, if it doesn't work for your face, you can use it on your hands or legs. That's how I use up all my unwanted skincate products.
