REVIEW on TIA'M My Signature C Source

.

A vitamin serum filled with vitamin C that tends the dark and dull skin with bright and clear vigor.

.

.

The TIA'M My Signature C Source is a renewed version of the O.S.T C20.

.
Only the name changed from the Original Pure Vitamin C20 Serum to TIA'M My Signature C Source.

.
The ingredients and the effects are the same as before.

.
It is a vitamin serum that tends the skin elastic with vitamin C, not vitamin C derivatives.

.

.

It says 'After opening, replace by pipette to use.' on the top of the box.

.

.

Simple instructions and how-to's on the back.

.

.

There is a dropper and the product in the box.

.

.

Vitamin C is very sensitive to temperature change, heat, and light - the brown bottle and the separately packed dropper.

.

.

Open the cap and exchange it with the dropper!

.

.

Done.

.

.

Store it in a refrigerator in order to keep it fresh.

.

.

Now that we know what it looks like, let's check the texture.

.

.

Quite watery.

.

.

It flows like any other liquid, but it's still very tight.

.

.

Absorbed clean without stickiness.

.

.

A drop or two should be enough on the face.

.

.

More than that, and your skin will become sticky with a white mark.

.

.

It could be slightly dry when applied by itself, so I recommend the vitamin cream of the same line to use it with.

.
TIA'M also states that a moisturizing product will help absorb the vitamin.

.
I use this serum as a night care serum, but if you use it under the daylight, you MUST apply sunscreen.

.
Lastly, try to avoid products containing AHA, BHA, and retinol.

.
Also, some white crystals might form - it's harmless vitamin C.

.
It might hurt your eyes as well, so don't put it in your eyes.

.
I hope you enjoy this serum to tend your skin clear and bright.
