Hi Beauties,
Korean cosmetics has stormed the world with their advanced technologies and focusing on achieving flawless healthy skin with skincare products. Korean brands has even come up with dupes that are on par with department brands and it has quickly became a staple in many women's' skincare routines.
Vitamin C is already a well known ingredient for brightening and strengthening the skin's abilities to build collagen. This is a trend that has stayed and remain favourites by many. Even my friends have been telling me how amazing Vitamin C has worked on their skin.
This brand used to be called OST but it has changed the name to C20. Personally, I was very excited when I got to try C20(OST) Pure Vitamin C21.5 Advanced Serum.
Name are changed to Wishtrend.
So, here is my opinion on this fame product.
Here is the box. Do not throw the box away because the product is best kept away from sunlight and from heat.
The dark bottle is also to keep the products inside safe from sun ray. Vitamin C is easily destroyed by sunlight so keep it away from direct sunlight and heat.
I can hear the sound of gases when I opened the bottle. It is like opening a bottle of champagne.
The ingredients were simplified from 29 ingredients to 10 ingredients of Pure Vitamin C21.5 Advanced Serum.
Original Pure Vitamin C20 Serum (30ml)
Water, Ascorbic Acid, Ethanol, Sodium Lactate, Butylene Glycol, Glucose, Camellia Sinensis Leaf Extract, Rosa Davurica Bud Extract, Carthamus Tinctorius (Safflower) Flower Extract, PEG-60 Hydrogenated Castor Oil Sodium Hyaluronate, Bis-PEG-18 Methyl Ether Dimethyl Silane, Diethoxyethyl Succinate, Ammonium Acryloyldimethyltaurate/VP Copolymer, Xanthan, PEG-180, Gluconolactone, Beta-Glucan, Citrus Aurantium Dulcis (Orange) Oil,Zinc PCA, Panthenol, Niacinamide, Glycerin, Tocopheryl Acetate, Lecithin, Caprylic/Capric Triglyceride, Ubiquinone, Diisopropyl Adipate, Phenoxyethanol, Methylparaben

There differences of the two versions are:
-the new one removed the paraben, ammonium which are harmful to the skin
- the new one removed alcohol which is quite high in the original version
-the old version is sticky and most people doesn't like it
-the old version has glucose which a form of sugar
-old version is cheaper in term of price
-the new one do not have any pore clogging or any irritants
Recommend:
Pure Vitamin C21.5 Advanced Serum is recommended for :
Brighter skin & whitening.
Skin pigmentation and blemishes.
Dry, unhealthy skin.
Uneven skin tone & discoloration.
Rejuvenation & nourishment.
**not recommend to just use it alone to treat skin that has active acne.
How to use:
1) Use day and night after cleansing and prepping the skin with toner.
2) Put about 1-2 drops of the C20 Vitamin Serum on to the hand and apply to dull and sagging areas.
(Avoid sensitive areas such as the eye, lip, or any scarred area, and use on the face as a whole.)
3) In daylight or outdoors, always apply sunscreen (with at least SPF15).
4) A slight tingle sensation may be felt at first use due to the pure vitamin nature of the product.
Important TIPS: Please keep inside fridge to use it for a longer time and to keep the product potent. Apply light water based toner or essence before applying the serum for better absorption. Products get absorbed into the skin faster when the skin is wet.
At night, I followed the same routine except no sunblock.
If I am using sleeping mask, I follow this routine. cleansing, toning, eye cream, pure vitamin 21.5 and then sleeping mask. The effect will be more obvious when I am using mask. =)
I think it is really a great product for those who can't use retinol as Vitamin C works to build collagen on the skin too. I will purchase this product again for sure!
C20 (OST) Pure Vitamin C21.5 Advanced Serum is another amazing Korean serum for brightening and for anti ageing. The price is very much affordable compare to other products that use Vitamin C as its main ingredient.
**Words of caution, this is not for treating acne but you can use this to treat the red scars left by acne.
** Also do not shake the new bottle or else you will have all the precious vitamin C 'erupt' out of the bottle.
*** Usage INSTRUCTION: cleanser>hydrating toner> vitamin C21.5 serum> moisturiser . Unless you want to increase the capability which can make your skin red, raw and sensitive from overexfoliation then you can try use it right after cleansing.
You can made your choice between the old version or the new version as generally there is mixture of reviews on the old and new version of the Vitamin C.
If you talk about texture I will prefer the new version as I really dislike stickiness and the fact that the company removes the paraben and other potential ingredients that are irritants to the skin.
However, if you have really dry skin and for budget friendly, then go for the Original version. It will also works better during winter than in summer.

The liquid is clear with yellowish tinge. As for the texture, it is watery with a little trace of oil. That is to be expected since vitamin C has a little tacky texture in their natural form. I don't think it is sticky at all. Of course it feels even better if you mix with a light moisturiser.
The C20 pure vitamin C 21.5 smell of light orange =). Don't worry as the smell disappeared along with the application.
It is said that one can feel a slight tinge on the skin. I experience that only on the first day and also on area with broken skin. However, it does not cause more damage but help to fasten the healing speed on that area. So I will say it will work better if your red acne scars are new. Also if you want to enjoy those tinge feeling, then you can definitely feel it if you have area to 'heal'. Most of the time, your skin get accustomed to the ingredients so your tolerance will become higher but it does not mean that it is not working on your skin. C20 21.5 definitely speed up the skin ability to renew itself that slow down with time.
I can say that my skin heal faster and make it look fabulous than when I am not using it. It works with my other skincare products as well.
I think Pure Vitamin C21.5 Advanced Serum has really versatile way of applications.During the day, I use three drops and mix it with my moisturiser on my face. Then, I apply sunblock.
Sometimes, I will just mix it with my toner.The C20 pure vitamin C 21.5 smell of light orange =). Don't worry as the smell disappeared along with the application.
