Thoughts & Opinions

I truthfully was quite happy with this product and would 100% purchase it! I also loved the consistency of the serum. Compared khổng lồ serums I have used in the past, the OST Original Pure vitamin C20 Serum had a lovely lightweight & breathable feeling on the skin. However, if you use too much serum, it can start lớn feel sticky và 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 khổng lồ be) You experience an instant pore tightening effect when applied lớn the skin. It cools and refreshes the skin & 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 khổng lồ it, a fragrance you would expect from a powerful vi-ta-min 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 khổng lồ be able to lớn enjoy this sản phẩm every day with no irritation lớn my skin!


I loved this serum và I fully enjoyed every bit of it. This in my personal opinion is the perfect serum for any skin type to lớn enjoy. It is lightweight enough for oily skin types, gentle enough for sensitive skin type, hydrating enough for normal and combination skin types & provides the right level of nutrients for any dry skin type khổng lồ 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 khổng lồ 5 Crema Claims

– Works best in combination with OST Original Pure vi-ta-min C20 Serum lớn boost effects for best results.– Overall skin tone brighteningSoft and Light texture– Increases absorption of vi-ta-min c into the skin– Best chất lượng of hydrating ingredients– Overnight skin repair & 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 vi-ta-min 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 & 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 lớn dry, sensitive và 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 & can leave the skin “appearing” shiny & oily, making it unsuitable to lớn 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 và cured them over night. I would always wake up in the morning with lovely, supple, smooth and hydrated looking skin that look refreshed và soft. It helped to lớn 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 lớn break out. You would be just fine with the serum alone.


I really loved this night cream. In combination with the serum, they both worked quickly on my skin khổng lồ 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 form size and providing deep hydration and moisture. Not lớn mention once again the price of this night cream is extremely affordable in comparison khổng lồ other night creams. The OST vitamin Sleep 9 lớn 5 Crema night cream costs $25.99 on Wishtrend.com which is a great price for such a good chất lượng product!
