Hello everyone!
Today I will be reviewing the ever so popular vitamin c serum, OST Original Pure Vitamin C20 Serum and the OST Vitamin Sleep 9 to 5 Crema from Wishtrend.com!
A while ago (about 3 months ago) I was given the OST Original Pure Vitamin C20 Serum and the OST Vitamin Sleep 9 to 5 Crema to try out and review. Wishtrend was kind enough to let me take as long as I needed to fully try and test these 2 products to make sure I could experience them to the fullest. So I took the opportunity to use them for 3 months to see how my skin reacted over time.
So let’s start the review!
I will first talk about the OST Original Pure Vitamin C20 Serum. This serum is the number 1 selling item on Wishtrend.com selling hundreds every day! As you may guess from the name of the product, it is a highly concentrated vitamin C serum designed to deliver your skin with the most adequate amount of vitamin C so you can see results fast! Vitamin C has many great benefits to the skin, some include, increased moisture retention, skin hydration, antioxidant power (the best form of anti-aging), increased collagen production and best of all, it provides the skin with a brightening effect that can reduce and improve the appearance of pigmentation from sun damage and post acne scars and can even help improve acne break outs! All these amazing benefits of a vitamin C serum really made me want to give the OST Original Pure C20 Serum a try so I could see for myself how it could improve my skin issues since I suffer from post acne scars. Like I commonly say in my skincare posts and reviews, I have sensitive, combination and acne prone skin. Having skin like mine can make finding products challenging since it’s so easy for a product to cause me irritation. So I was a bit nervous about trying the OST line. However I trusted if because it is such a raved about product on Wishtrend!
Some of OST Original Pure Vitamin C20 Serum claims
- – The serum is always made fresh and sold right away, making sure you receive fresh ingredients for the best skin results.
- – It contains a 20% combination of L-ascorbic acid with natural vitamin C antioxidants to aid in the prevention of the first signs of aging.
- – It revitalizes, removes dead skin cells, whitens, tightens pores, fade acne scars and helps remove and prevent blackheads.
These are some pretty large claims! I was very excited to put this serum to the test and see how well it could hold up to it’s claims. I was most interested in looking for an improvement in my skins pigmentation issues as well as seeing an improvement in controlling my acne breakouts.
My Skin Over a 3 Week Time Span
I applied the serum to my skin every morning and night to maximize my results. I would apply is after washing and toning my skin. After applying, I would let the serum absorb completely into my skin before applying any additional products. It is recommended on the Wishtrend website to keep the OST Original Pure Vitamin C20 Serum in the refrigerator after opening to maintain its quality and potency as well as to help provide and instant calming and cooling effect when applied to the skin. I made sure to always keep my serum in the refrigerator to help preserve it’s quality. I took photos of my skin every day for a time span of 2.5 weeks so I could track my overall skin improvement and results of the serum. Here are my results after only 2.5 weeks!
When comparing the photos, you can easily see in Day 1 My skin was very red and looked irritated as well as has visible risen pimples. After 1 week, the pimples on my skin had significantly reduced in size and the overall redness in my skin had reduced as well. However, there still was some visible purple undertones to my post acne scars. After 2.5 weeks you can easily see that the redness in my skin was almost gone and there were no longer and risen acne pimples. The purple tone to my post acne scars had also reduced and my skin had started to gain a more even tone! The results I gained in 2.5 weeks were quite amazing! My Overall
Thoughts and Opinions
I truthfully was quite happy with this product and would 100% purchase it! I also loved the consistency of the serum. Compared to serums I have used in the past, the OST Original Pure Vitamin C20 Serum had a lovely lightweight and breathable feeling on the skin. However, if you use too much serum, it can start to feel sticky and tacky on the skin, but when the right amount is applied ( 2-3 drops ) you experience a lovely lightweight texture that provides an instant glow. When the serum is stored in the fridge (how it is recommended to be) You experience an instant pore tightening effect when applied to the skin. It cools and refreshes the skin and tightens and closes the pores! It truly is quite the refreshing feeling. Especially on hot summer days! I even enjoyed the smell of it! It has a true Orange Citrus smell to it, a fragrance you would expect from a powerful Vitamin C product. I have heard some people saying the Fragrance was too strong for their liking, however, I personally had no issues with it. Irritation wise, I experience none! I have sensitive skin so I was pleasantly surprised to be able to enjoy this product every day with no irritation to my skin!
Overall
I loved this serum and I fully enjoyed every bit of it. This in my personal opinion is the perfect serum for any skin type to enjoy. It is lightweight enough for oily skin types, gentle enough for sensitive skin type, hydrating enough for normal and combination skin types and provides the right level of nutrients for any dry skin type to use. It truly is a universal serum for all skin types! Even the Price of the serum is excellent running at an original price of $24.99 on Wishtrend.com. It is an extremely affordable serum.
OST Vitamin Sleep 9 to 5 Crema Review 
In a addition to the OST Serum, it’s partner product is the OST Vitamin Sleep 9 to 5 Crema. This is a night cream that has been specially formulated to work in combination with the OST C20 Serum to maximize the effects over night while you sleep while also provided deep moisture, repair and boosted vitamin C. I received this cream along with my serum so that I would better be able to test out the entire Vitamin C series from OST. I used the OST Vitamin Sleep 9 to 5 Crema along with the serum from day 1. I wanted to test them in combination like how they are designed to be used so I could gain the best results in a short period of time.
OST Vitamin Sleep 9 to 5 Crema Claims
- – Works best in combination with OST Original Pure Vitamin C20 Serum to boost effects for best results.
- – Overall skin tone brightening
- Soft and Light texture
- – Increases absorption of vitamin c into the skin
- – Best quality of hydrating ingredients
- – Overnight skin repair and moisture
The claims of this night cream more or less state that the cream is best used along side the Serum so your skin can receive the most ideal amount of vitamin c. Since the cream is designed to be used with the serum, I made sure to do just that and use it every night after my serum so I could achieve the best results. 
My Overall Thoughts and Opinions I actually really enjoyed this night cream! Like I mentioned earlier, I used it as directed from the Wishtrend website, using it as a night cream after using the OST C20 Serum. With my skin type being combination to dry, sensitive and acne prone, I found this cream should ONLY be used at night sparingly. It has a wonderful lightweight texture however it provides an intense amount of moisture and can leave the skin “appearing” shiny and oily, making it unsuitable to use during day time. However, these features make sense since it is only meant to be used during the night while you sleep. I mainly enjoyed this night cream because the texture instantly smoothed over and reduced the appearance of dry patches on my skin and cured them over night. I would always wake up in the morning with lovely, supple, smooth and hydrated looking skin that look refreshed and soft. It helped to control my dry areas on my face such as my nose, jawline and cheeks. The fragrance of the night cream matched the serum with a lovely Orange citrus scent that reminded you that your treating your skin with a lovely amount of vitamin C. Because of its deep moisture properties, if you have an oily skin type, I would not recommend the night cream to you. It would be too rich and most likely cause you to break out. You would be just fine with the serum alone.
Overall
I really loved this night cream. In combination with the serum, they both worked quickly on my skin to control my break outs, cure my dry patches of skin, fade existing post acne scars and prevent to appearance of new ones. All while controlling pore size and providing deep hydration and moisture. Not to mention once again the price of this night cream is extremely affordable in comparison to other night creams. The OST Vitamin Sleep 9 to 5 Crema night cream costs $25.99 on Wishtrend.com which is a great price for such a good quality product!
