## Description

Numbuzin No.6 Deep Sleep Mask Serum, 1.69 Fl.oz / 50ml | Dull, Dry Skin, Moisturizing, Water Glow, Elasticity | Refreshing Skincare For All Skin Types | Smooth Application | Easy Absorption : desertcart.in: Beauty

Review: I love it - Really helps my hypersensitive, combination skin. It’s the only serum that doesn’t break me out. I’ve been using it for quite a while now and it makes my skin feel moisturised from inside, especially when I use it as part of my night routine. Several times when my skin feels iffy, I don’t like to layer products as it causes breakouts and so I only apply a slightly increased amount of this and lightly pat it in and wake up with happy skin
Review: Superb. - Honestly, Initially I was sceptical about this as it seemed like plain water and I thought I wasted my money. But but.....but, after few usages I realised it's magical. It mimics sheet mask in efficacy. This is my holy grail on bad skin nights or if my skin is healing from a Breakout. I just apply this and a moisturizer. It's super soothing and leaves skin healthy through night. Will be a permanent part of my skin care now onwards..

## Questions & Answers

**Q: Can I layer serum 6 with either a vitamin c or retinol?**
A: Probably not with retinol since there's niacinamide

**Q: Is this supposed to be a very watery and runny? I'm used to a serum typically being a bit thicker I just want to check if what I got was right?**
A: Yes it is watery. I like it because it’s natural made out of glacier water and hydrating.

**Q: How many times a week should I use this product?**
A: You can use it as many times as you want! 
You can put 1 layer both day and night but at night if you want extra hydration, try 2-3 layers! :)

**Q: Would I use this before no 3 or after?**
A: Not sure if you are referring to the number 3 toner or serum. If the toner then I would say serum 6 after the toner.
