  • Given the nature of Vitamin C, the Tiam My Signature C Source may crystallize around the opening of the bottle. This does not alter the quality of the product. Upon opening, you may notice a fizzing sound (like opening a bottle of soda) and the product may bubble up. Just let it sit for a while and the bubbles will disappear. Don't forget to put it inside your refrigerator. 


Review(s) on Tiam My Signature C Source:

"This product is a must-have for those who have acne scars. I use this at night after my BHA toner to improve its efficacy. I saw how potent it is when a drop in my hand hand oxidized right before my eyes. All the goodness of vitamin C in your fingertips, literally.

The consistency is like that of honey and I just love the citrus smell so much. It's a bit thick  so it needs more time to get absorbed into the skin. The first time I used this, I felt a slight tingling in my skin so I used it every 3 nights at first until my skin adjusted and I've been using this alternately with my AHA or BHA. 

I know that this helped me completely eradicate the hyper-pigmentation caused by my cystic acne.  It will take time and patience of course but it's worth it. Your skin will love this as it will nourish your skin inside out. I always wake up to a healthy glow whenever I use this at night. Highly recommend this product." - Arianne
