[OST] Original Pure Vitamin C20 Serum

This Vitamin C20 Serum was one of the best selling Vitamin C skin care products in Korea and was viewed on par as other famous brands such as Estee Lauder! In fact, it placed within the Top 3 serums at the Sure Beauty Awards and was fondly referred to as " the miracle in one red bottle"

The unboxing

This product offers all the benefits of vitamin C combined with a brightening and peeling function. It also provides a high moisture content for smooth, hydrated skin, evens out skin tones and removes blackheads. As indicated by its name, "the miracle in one red bottle", the packaging is a glossy, red-orange box with English instructions. 

The product is boxed securely to prevent oxidation of the serum. First, the glass vial is heavily tinted and the bottle sealed to impede any contact with sunlight and oxygen.

As such, before use, the seal must be broken and the dropper (which is packaged separately) must be fixed on. The serum must also be refrigerated once opened. 

The reveal

The serum itself is a smooth liquid which offers a lovely citrus-y fragrance.

The product is highly hydrating but can be a little sticky for some. In which case, simply mix a little with your toner or moisturizer. ♡♡

Many people have reported amazing benefits of using this product! In fact research has shown the following outcomes:

• 97.91% - skin looked brighter and complexion better
• 96.00% - serum reduced unwanted skin pigmentation and blemishes
• 92.20% - experienced a positive outcome after first usage
