#OOTD Vitamin C Brightening Hydrogel Mask, 5 Sheets: See the Vitamin C hydrogel texture

View transcript
Hydrogel masks have become an essential part of my weekly skincare routine. Let me put you on.

Today, the hydrogel mask I'm gonna be using is the Vitamin C Brightening Hydrogel Mask from #OOTD. This is gonna help brighten up my skin complexion, even out my skin, and help with any dull or dark spots that I have on my face.

In part one, you saw me wash my face with the brightening Kiwi Vitamin C Cleansing Oil, also from #OOTD, and now I'm gonna keep the Vitamin C party going with their hydrogel mask.

So I usually like to do hydrogel masks at night while I go to bed, so I could just sleep in it overnight and let my skin soak up all of that great skincare. But I'm just gonna be doing a bunch of chores around the house today, so I felt like it was the perfect time to put one of these on.

The goal is to keep this on until this white turns into this clear gel. That means your skin has fully soaked up all of that amazing vitamin C goodness.

I'm gonna leave this mask on for a few hours, and I'll come back and show you the results in a bit.

Okay, it's been a few hours. You can see it is completely gelled and clear on my face. Now let's take it off.

Wow... look at that beautiful glow. Oh, I'm like staring at myself in the mirror and the phone at the same time, because that glow is crazy.

This is exactly what I love about hydrogel masks: you see the results of them immediately. You literally see the difference in your skin. They're incredible.

The Vitamin C Brightening Hydrogel Masks come in a pack of five. I like to do these once a week, so you're getting over a month of product in here.

#OOTD Vitamin C Brightening Hydrogel Mask gives your routine five cooling, close fitting masks for a fresh glow focused pause. The gel texture gradually turns transparent during wear and leaves skin feeling soft, smooth, and refreshed.

Niacinamide and ascorbic acid bring the blend's vitamin C focus, while hydrolyzed collagen, turmeric root extract, tocopherol, and glycerin support a dewy, comfortable finish.

Use after cleansing and toner, then follow with moisturizer. Finish with sunscreen if using it in the morning.
