The TIA'M My Signature Red C Serum is the newest addition to the TIA'M vitamin C family. Formulated with glutathione, vitamin B12, and 20% vitamin C, the My Signature Red C Serum fades age spots and hyperpigmentation from blemishes while repairing oxidative damage that may lead to wrinkles and sagging. All ingredients work together to minimize melanin synthesis, resulting in skin that's bright and even-toned, with zero dark spots. Size: 30 mL To use: After cleansing, dispense 2-3 drops and apply evenly onto face. Pat until fully absorbed. In the mornings, remember to put on your SPF! Note(s): - Store in the fridge to prolong shelf life of the product. - Avoid using this serum with products that contain high levels of AHA, BHA, and retinol. - The red hue is a naturally-occurring pigment due to the vitamin B12 present in the formula.
