Vitamin C is such a superstar active that really provides a whole range of benefits to the skin when added to your skincare routine. This potent antioxidant helps to brighten age spots and hyper-pigmentation, or discoloration of the skin, including age spots and dark circles under the eye. Additionally, it has been shown that topical applications of vitamin C serums helps to boost collagen production in the skin, leading to reduction as well as prevention of signs of ageing such as wrinkles and loss of elasticity. Out of the many different types of Vitamin C, Ascorbic acid—also known as L-ascorbic acid is the royalty of Vitamin C and is backed by the most skin-related research proving its effects.

To be honest, I was quite apprehensive about adding Vitamin C to my skincare routine despite all the benefits that it’s touted to have. It was because I had a bad experience when I used Paula’s Choice Vitamin C booster serum. I started developing red rashes on my neck area while I was using that particular product. Since then, I developed a phobia of using a dedicated Vitamin C serum in my skincare routine. The reason why I wanted to incorporate a Vitamin C serum back into my skincare routine was because I discovered that I was developing post-inflammatory hyper-pigmentation (PIH) marks from my hormonal acne. The PIH either took a really long time to fade or still stubbornly remains there despite my best efforts with using acid toners. I knew that Vitamin C was key to fighting PIH. So I searched on the internet for some suggestions on Vitamin C serums to try and that’s the product that we are going to talk about today.

Wishtrend’s Pure Vitamin C21.5 Advanced Serum is a relatively inexpensive Vitamin C serum, formulated with Ascorbic Acid, that seems to be popular. I had been using it for around 1.5 months and I’m ready to share with you my thoughts on this product.

As usual, let’s check out its ingredients, shall we?


Hippophae Rhamnoides Water (70%), Ascorbic Acid (21.5%), Sodium Lactate, 1,2-Hexanediol, Sodium Hyaluronate, Panthenol, Cassia Obtusifolia Seed Extract, Allantoin, Xanthan Gum, Ethyl Hexanediol

How does the Wishtrend Pure Vitamin C21.5 Advanced Serum fare?

The Wishtrend Pure Vitamin C21.5 Advanced Serum is an upgrade from their original C20 serum. In the new formula, the percentage of Vitamin C has been increased from 20% to 21.5% while the sticky feeling that the old C20 serum has been lowered. I hadn’t use the C20 serum before so I couldn’t really make a comparison for you guys.

As I had mentioned earlier, I wanted to use a Vitamin C serum mainly to combat my PIH left behind from my hormonal acne. If I experience any other beneficial effects from Vitamin C, I’ll take it as a bonus. When I first used this product, I applied a whole pipette-full of product onto my skin after using my pH adjusting toner. I felt a strong stinging sensation and my face actually heated up and was slightly flushed. I think that amount must be too much for my skin to take in at once. Even though the stinging went away after around 10 minutes, I was worried about agitating my skin (remember my previous bad experience with Vitamin C serum that I’ve talked about above?). Thereafter I adjusted the amount of product to be just 5 drops and it was much better tolerated by my skin without any stinging. I noticed from the get go that this product is rather drying so I pair it with my hyaluronic acid serum after I let it sink in for around 15 minutes. I also need to adjust the amount of moisturiser I use in order to combat the feeling of dryness. However you need to note that I’ve got combination dry skin so if your skin is oily, you might not be hit so much by its drying effects. Anyway, this product doesn’t offer instantaneous results. In fact, I only noticed some initial results after about 3 to 4 weeks in. My skin tone was more even, brighter and also rosy. Surprisingly I also noticed slight firming of my cheek areas and the nasolabial lines are less noticeable. As for my PIH, I noticed very slight lightening on my left lower cheek around the 5 to 6 weeks mark but not much improvement on the right side. I’ve read that it takes about one year before a significant improvement could be seen so I’ll continue using Vitamin C in my routine to see better results.

Below are my photos showing my skin condition before and after around one month of use. Please note that the lighting in the photos are not exactly the same. The small red arrows show the location of my PIH. The PIH right at the bottom is slightly lightened while the older PIH at the top are still around.

You’ll need to note that since Vitamin C (and especially Ascorbic Acid) is notoriously easy to oxidise, it’s best that you keep this product in the fridge to extend its lifespan. Applying oxidised Vitamin C is not only of no benefit to your skin, it might actually further introduce free radicals to disrupt your skin. This product is basically colourless and that’s how you know that it’s fresh. Oxidised Vitamin C has a very dark amber colour that is unmistakable so stop using your Vitamin C if it has changed colour.

Where can you find it?

You can purchase this product from Wishtrend’s online shop. It retails at US$24.99.

However, I bought this product from Q010.sg. It retails at S$29.80 (30 ml sized) when I bought it but I think that it was a promotional price.

You can also purchase it from MyBeautyMoments.com. They have a promotional price of S$28.50 for this product.

Thank you for reading!
