Skincare Review: OST Original Pure Vitamin C20 Serum
The first time I used OST Original Pure Vitamin C20 Serum, I experienced a not-so-pleasant tingling sensation like stated. It didn’t necessarily sting but it was very close to it. I do worry for the sensitive skin users because I have combination skin and experienced it quite heavily. Though I do have dry patches and active acne which is probably why it stung more. After the first use, it gets better as your skin adapts to the ingredients.
Three drops is all you need for one application and I use it after showering. My routine goes from cleansing, toning, serum and then moisturizer. I spread it lightly (because it seems to develop into a milky texture when rubbed too heavily) to warm up the product and then either spread or pat it into my skin.
I rate this a 4/5! This product has helped with my skin, especially for my pores, and I thoroughly enjoyed using it. Would I repurchase this? Yes and no. Depending if I can find a better working serum for fading acne scars! I wouldn’t call this an essential product but it definitely made my skin better so it depends on what problems you’re trying to target. With that being said, the serum has already been incorporated into my daily skincare regime!
The product is best used in conjunction with their Vitamin Sleep 9 to 5 Crema and First Boosting Essence
