I’ve been using Vitamin C serum from the brand C20 for a few months now, and so far my skin has reacted positively to it. Acne was mildly reduced, my blemishes became less obvious, and my skin is smoother than before. But now that there are so many brands offering Vitamin C serums, I thought, why not give those a try? So, here’s my trial of Korean brand Elizavecca‘s Vitamin C 100% Powder + Vita-Multi Whitening Source Serum.
Instead of the normal single-bottle packaging, this product includes 12g (0.42oz) of 100% ascorbic acid powder contained in a fine-tipped clear bottle, and 50ml whitening serum contained in the larger, labelled dropper bottle. The powder is refined and white in color, while the serum is packed with arbutin, green tea extract, Q10 and collagen, and appears as a clear, watery liquid. The combo also comes with a smaller brown dropper bottle for mixing the powder and the serum, or you can mix them directly in your palm.
Pour powder onto palm.
Add serum to powder until it dissolves completely.
Blend with finger and apply the solution to your face.
Pour powder into mixing bottle.
Shake well and apply the solution to your face using the dropper.
I prefer blending directly in my hand since it mixes better and doesn’t waste any product. Also, the dropper doesn’t reach the bottom of the bottle, which means you’ll have to make more of the solution than what you might need if you wish to use the dropper. The opaque nature of the mixing bottle also means it’s hard to gauge if you’ve added enough serum to dissolve the powder.
The solution feels a bit prickly and itchy on the skin (do not use if you have any open wounds), but the uncomfortable sensation soon goes away. I’ve been applying this every night before sleeping for two consecutive weeks, and so far its performance is as good as my old C20 Vitamin C serum.
One of the biggest issues with Vitamin C serum is that it tends to oxidize and discolor easily. And when it turns orange, it stains my pillow case in addition to being possibly less effective on skin. Powdered Vitamin C prevents this from happening, but is less handy. Sometimes the powder gets stuck at the tip, and the small dropper bottle seems redundant. Taking into account the relatively higher stability of powdered Vitamin C over its solution form, I’ll probably take Elizavecca’s Vitamin C 100% Powder + Vita-Multi Whitening Source Serum when I travel, leaving my C20 in the fridge to be used at home. I’ll also be wearing sunscreen in the daytime as a counter-measure to Vitamin C making my skin more photosensitive.
