There was some improvement
I have been using this product for under 10 days so I guess you can say the bottle lasted for a week, but I know there are some people out there that can push the bottle to last longer. I asked people around if they've seen my face improve at all lately and i got some "not really" in response. It does work and has improved maybe some or a little but you can ask for speedy results for under a week, but the product smells alright to me.👍 Maybe there would of been more improvement on my skin over time if I had more of that stuff to put on but I ran out.

Brightened my dark spots
Thanks to recommendations on TikTok, I stumbled upon this remarkable serum, and it has truly become a game-changer in my skincare routine! Having tried various Vitamin C serums from both American and Korean brands in the past, I can confidently say that this one stands out. Not only has it effectively brightened my dark spots, but it has also brought a newfound radiance to my complexion. What's more, the affordability of this serum compared to the American brand I had been loyal to for over two years is simply astounding. I'm thrilled with the results and can't recommend it enough. I firmly believe that others can benefit from its transformative effects just as much as I have. It's a must-try for anyone seeking radiant, even-toned skin without breaking the bank.

Best skin product for aging skin
I'm 45 years old and huge on taking care of skin and making sure that my skin stays healthy and glowing. This product is my holy grail I use it morning and night along with my other serums and moisturizer. I promise you will not be disappointed. Make sure you stay consistent and over time you will see the affects. Smoother skin and many spots start to diminish.

4 stars for NOW, I JUST got it!
This isn't going to be my final review on this since I only just got it 2 days ago and I have high hopes! But as far as initial review, the bottle is so pretty on my bathroom sink 😆, I love that even if it doesn't fix my spots that it has a good amount of Hyaluronic acid in it so it will always cover SOMETHING for me in a beneficial way, and I don't know what people are talking about but the smell is DEF STRONG, it's not bad by any means but it's VERY much smells like I'm smothering grapefruit juice all over my face so it's def filled with vitamin C lol its strong at first but once you put other things on your face afterwards you don't smell it anymore 👍🏻 I feel like once I put it on it makes the parts of my face that are clear look at least brightened which may be the HA or the vitamin C I'm not sure, but I have high hopes for this stuff so I'll rewrite this review in 2 weeks. I've tried so many american vitamin c serums and had tried the GOODAL vitamin C serum (koreas #1) and also have the Melano C serum (Japan's #1) and got meh results tho I'm still spot treating and hoping it does something over time. I have a lot of acne scars and freckley sun damage

Gentle vitamin C, not sure if its reducing scars
I have scars that are pretty hard to get rid of. Tried a lot of vitamin c's and none of them helped fade them. However I liked that the Dr.Althea was gentle and didn't burn or hurt my face. So I will continue to use it every morning.

One of the Best Vitamin C Serum
This is honestly one of the best vitamin c serum I ever used. I had some dark spot from old pimples and whatever I used wasn't helping. One of the youtuber I watched said this works amazing, so I bought it to see if it'll help with my dark spot and omg, it literally lighten up my dark spot after only 2-3 days. Also, I have sensitive skin, but this product was so gentle and didn't irritate my skin.

“Brightens Skin and Leaves a Healthy Glow!”
I’ve been using this Vitamin C Boosting Serum for a few weeks now, and I’m really impressed. It has a lightweight, non-greasy texture that absorbs quickly, leaving my skin feeling smooth and refreshed. After using it consistently, I’ve noticed a visible improvement in my skin tone—my complexion looks brighter, and some of my dark spots have faded. The serum also has a nice, subtle citrus scent, which is refreshing. I appreciate how my skin feels hydrated and rejuvenated without any irritation. It’s now a staple in my skincare routine, and I’ll definitely keep using it!

Very moist and well absorbed
Purchased three items from this brand as I loved their other products I tried a few years ago and I am happy with all these items I bought this time. The Vitamin C serum doesn’t have any scent but it’s extremely moisturizing and leave my skin glowing. Will see after 10 days how much improvement my face got 😆 excited to see the result and will keep you all posted! Definitely recommended!

Good stuff!
I got this after seeing it on tiktok and was pleasantly surprised! Very hydrating serum and felt great on my face. I took a break on vitamin c for a while because I couldn’t find any I liked but this put me back on it! I can’t say if it did too much for my overall skin but I felt like it was doing its job it just may have been more subtle than I was hoping for. Or maybe my skin just looks as good as it can get. The smell of this serum is very earthy. Would buy again if in need of a cheaper option. Will be buying this for my fiancé soon.

So far so good!
I've tried a vitamin C serum only once before and it was too reactive with my skin/made me itch with just one use. With this one from Dr Althea, I've used it maybe 3-4 times so far and no issues! That is a really big thing for me since I have very sensitive skin. Will update if and when I start seeing updates on my hyperpigmentation.

It’s good but I’ve had better
I follow a girl on TikTok who swears by this Vitamin C Serum. I had been at the store and bought the Cocokind Vitamin C Serum and I personally will swear by that. I have Milia on my cheeks and at that time they were the most obviously and amount I’ve had. You can’t pop Milia like a pimple but sometimes they would go down a bit on their own. within two weeks my cheeks got itchy and my of them started extracting themselves. It also helped a lot with dark spots/scars on my face since vitamin C is so helpful with skin cell turnover. When I ran out of the cocokind I finally tried this one and it’s good. Personally for my skin the cocokind is better and has helped me so much but I still recommend this one as I know others like it. It’s a bit more watery for me and I didn't experience the same healing of my skin while using this bottle and had acne and scaring from a medication switch while using it. I’m almost out and will probably get the cocokind again then. :) hope this helps anyone looking to learn more! The other was just absolutely worth the money and this one I personally didn't see results or just continuing healthy skin while using it.

I have very sensitive skin and a lot of redness. I was hesitant to buy since my skin had not reacted well with many vitamin c's but let me tell you that I'm glad I bought this. It really absorbs well into the skin, no stickiness very mild smell. This has done wonders to my skin.

Loved, but it ending up being too strong for sensitive skin. :(
Initially, this serum was great. I got it for brightening and for reducing hyperpigmentation, and it did help with both of those issues significantly while being hydrating! Also, it smells great - like literal oranges. The only issue was that I have sensitive skin, so for me, the serum was too strong. I started developing really dry patches on my face where I had applied the serum, and had to stop using it altogether since spacing out applications didn't solve the problem. If it hadn't been for that, though, I would definitely still use the product.

Not bad, but not my favorite
I used up all the boosting serum and didn't see a noticable difference in my skin. It felt nice, was unscented and made my skin look glossy. But that's about it. It's a good buy to try out, but I don't think I will repurchase because I'm wanting to try other Vitamin C serums out on the market.
