Review: Ost Pure Vitamin C21.5 Advanced Serum

Being the girl who loves trying new beauty products, I had to try something new after finishing my second bottle of InstaNatural's (20%) Vitamin C serum! Luckily, I got the opportunity to test out a new serum: WishTrend's OST C21.5 Serum. The C21.5 Serum is an upgrade from the C20 Serum. Although I haven't used the C20 serum, I did a little research on the difference between the two.

 Packaging 

This serum comes in a dark-colored, glass container, which is great, because Vitamin C tends to degrade from light. This dark glass helps slow down that process. Additionally, this serum came with two tops: a cap and a glass dropper. The cap was very useful for me during my travels, so it was great that both were provided!

 Physical Properties 

This serum is very smooth and watery--it's not very sticky, but still is a little bit sticky to touch. The color of the formula is clear. Unfortunately, I can't quite tell what the scent is, but it's more medicinal and herbal than orange-y in scent. However, this does indicate that there's no added fragrances!

 Ingredients 

According to CosDNA, all of the ingredients used in the product are very safe and paraben-free, and none of the ingredients are acne-causing or irritating. Isn't that great? 

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

CosDNA

Vitamin C, in this case ascorbic acid, is one of the few beauty ingredients that has proven to help with fine lines, wrinkles, and skin discolorations! It works by increasing collagen production and speeding up the body's natural repair mechanisms. It also helps protect against sun damage, but that doesn't mean you can toss out the sunscreen! 

 My Opinions 

Although I didn't quite like the scent of the product, it works quite well. I usually use 3 drops for my face, and an addition drop or two for my neck. Just a short side, be sure to apply products to your neck as well! Your neck needs as much care as your face! I've heard from other people that the older version stings (not the best for sensitive skin), but this serum applies very smoothly and makes my skin feel extremely soft. Moreover, the formula is absorbed very quickly. The longer I use the product, the brighter and clearer my skin looks. In fact, directly after applying the product, my skin has a healthy, dewy appearance. 

**Warning: be sure to keep this product in a cool place. The best place is to keep it in the refrigerator. This will decrease the rate of oxidation for your Vitamin C!

My christmas wishlist from WISHTREND

Hello everyone! As some of you may have seen, I'm a huge fan of Korean (and Asian) skincare. It's so much more thorough than what many Americans are used to--with up to 11 steps! It's hard to think that only a couple years ago, I never used any sort of skincare products--just good, old water and towel. However, after finding out about the importance of skincare, I've been strangely (and happily) addicted to Korean skincare and products. Not only are they effective and cute, but many of these products are of much higher quality that American products of the same price.

*Disclaimer: not sponsored*

Today, I'd like to introduce to you Wishtrend, an online Korean beauty store. There are few points that make Wishtrend stand out from other Korean beauty stores:

1. Well-integrated and very informative Youtube channel
2. Exclusive and hard-to-find brands
3. Huge range of products
4. WISHboxes with discounted prices on a collection of products

I think the main reason I really love Wishtrend is that they like to keep their customers informed. They do that through they Youtube channel and through their newsletters. I love listening to their videos and reading the newsletters because I definitely learn a lot from them. I also want to purchase every product they mention >__< hahaha. Someday, maybe.

Here are some examples of videos and newsletters in which they inform their viewers:
- [Newsletter] What does vitamin C do for your skin?
- [Newsletter] Exfoliation tips for different types of skin
- [Youtube] Basic skin type test & rules
- [Youtube] Best Skin Care Products for Body & 3 Essential Body Care Tips
- [Youtube] Autumn/Fall Skin Care 101 & Natural Moisturizers

My Christmas Wishlist

  

These two are what's known as the Wishboxes. They contain a few products sold at approximately 30-50% off! I really would like to try a few products this way!

If you've taken a look at this youtube video, you'll see that the last two items on my wishlist are from that video--truthfully, I wanted everyone in that video. >__<
