## Description

CONFIDENCE in your beauty sleep serum 30 ml.

Review: My doctor suggested mixing my tretinoin cream with a nice serum at night when applying and this is what I use. Only at night I use 1 pump of this and a pea sized amount of tretinoin, mix and apply. It goes on really well and my normal/oily skin loves it! I follow with IT Cosmetics Confidence in a Cream Hydrating Moisturizer. This combination gives my skin everything it needs to recover over night. I’ve been doing this for a couple of years. I get compliments on my skin! It is kind of heavy, but I like it for night time. For reference, I’m 43 and perimenopausal ;)
Review: I’d buy this over and over and over again. My skin feels amazing with this line of products. The serum feels warm going on, and it’s a bit thick/sticky and difficult to rub into dry skin, but the results are worth it! I feel so smooth after this. It brightens up my skin. I use under the matching moisturizer before bed.

## Questions & Answers

**Q: Can I use this product in the morning and night?**
A: You can use the product once a day either in the morning or at night, but we recommend using it at night, at the peak of skin cell repair. With continued nightly use, this serum also keeps working throughout the daytime to fight free radicals.

**Q: What does vitamin C do for your skin?**
A: Vitamin C is a powerful dermatologist-recognized antioxidant. As an ingredient, vitamin C is known to help defend skin against damaging free radicals, visibly brighten, and reveal a more even-looking skin tone.

**Q: Is this a good vitamin C serum for sensitive skin?**
A: This formula has been dermatologist-tested for safety and is suitable for sensitive skin. Should you have any concerns about adding new formulas into your skincare routine, we recommend patch testing and/or consulting your dermatologist before use.

**Q: What is the best way to store vitamin C serum?**
A: This product is best stored in a cool, dark place. We recommend a medicine cabinet or any place that is not in constant direct sunlight.

**Q: What is the smell of the product and where does it come from? Is this fragrance-free?**
A: No fragrance is added to the formula. Due to the high level of antioxidants and the combination of the ingredients (vitamin C, ferulic acid and polydatin), you might smell naturally occurring metallic and smokey notes, but this is normal.
