Affordable vitamin C serum’s fishy odor fades post-refrigeration, prompting repeat purchases despite initial scent concerns.
Strong fishy smell vanishes after chilling this vitamin C serum, making it a cost-effective skincare staple worth repurchasing.
This review is from Amazon.com for product:
COSRX Pure Vitamin C 13% Serum with Vitamin E & Hyaluronic Acid, Hydrating Facial Serum for Fine Lines, Uneven Skin Tone & Dull Skin, 0.67fl.oz/20ml, Korean Skin Care
I was looking for a good vitamin C serum that is also not on the pricey side and decided to try this popular one out. The product definitely smells very fishy when you first try it and that put me off at first. I couldn’t bear the lingering smell so I gave my first bottle away to a friend. I ordered it again for my mother who does not mind the smell as much and put it in the fridge for her. After about a week in the fridge, I noticed that the smell was not that bad anymore. Two weeks later, it was completely gone!!
So I ended up purchasing this 5 more times (for myself and others). Bottom line is, don’t let the fishy smell deter you from purchasing this item!
Vitamin Basics & Tips
Vitamin C (L-ascorbic acid) is a potent antioxidant widely used in skincare for its ability to brighten skin, boost collagen production, and protect against environmental damage. However, it is notoriously unstable and prone to oxidation, which can cause discoloration or unusual odors in formulations. Storing vitamin C serums in cool, dark environments like refrigerators slows oxidation, preserving efficacy and reducing scent intensity over time.
In daily life, pairing vitamin C with sunscreen enhances UV protection, while combining it with vitamin E and ferulic acid (as seen in many serums) stabilizes the formula and amplifies benefits. For optimal results, apply vitamin C products in the morning to neutralize free radicals generated by sun exposure. Note that some users may experience mild irritation; patch testing is recommended. Dietary sources like citrus fruits, bell peppers, and broccoli also support skin health from within.
