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!
