23 Skin: How to Make a DIY Seaweed Mask + Matcha Mask

DIY Seaweed Mask

Man, what is it about a self care day (or even like, 15 minutes) that makes us so damn happy? From a face mask, to a body scrub, to a relaxing bath (I only say that now ‘cause I actually have a bathtub), there’s something pretty magical about setting time aside to show our bods and minds some love.

Do you have a designated self care day? Mine’s Saturday, and that usually involves a face mask and a body scrub.

And I’ll tell you what, I don’t know much about seaweed but I do know that I want my body to be covered in it at all times from now on. This, a recent discovery in my use of 23 Skin, a DIY beauty brand that just came on our radar.

Is DIY Skincare the New Norm?

When creating 23 Skin, esthetician Shiri Sarfati set out to create good for you, nourishing products based on ingredients that are simple, well-sourced and nutrient-rich. There’s also an emphasis on the DIY element, which is growing in popularity (see this Observer article).

It’s no secret that the natural beauty industry has blown up. And while we’re psyched to see brands listing the toxic ingredients they’ve removed from their products, like parabens and phthalates, it can still be tough to understand exactly what’s actually in our products. Like sure my cleanser doesn’t have toxins in it, but are there good stuff in it too or is it just … neutral?

One thing that surprised me when reading about all this was water. Who know water could make things weird?

As Shiri says, “Water is the first ingredient in most skin care products, but the second you formulate with water you introduce the possibility for bacteria to grow. That’s why you need preservatives. And just because a product claims it’s paraben free does not mean there are no other preservatives. Otherwise you would have mold growing in your favorite skin care product.”

The idea behind 23 Skin is that ingredients should be simple, nutrient-rich and sustainably sourced. It’s pretty amazing if you consider it for a sec, that all beauty brands don’t think this way. Oh and another thing? Shiri believes skin care should be affordable. That everyone should be able to relax and enjoy a spa moment at home.

The two products 23 Skin offers are a Matcha Clay Powder and a Seaweed Powder. Both powders are:

  • Organic and natural
  • Fragrance free
  • Preservative free
  • Not tested on animals
  • Additive free
  • GMO free

There are literally two ingredients in the matcha clay powder (um, matcha and clay) and ONE INGREDIENT in the seaweed powder: seaweed, obviously.

Skin care doesn’t get any cleaner than that, my friends. But let’s take a look at the benefits of each.

DIY Seaweed MaskMatcha Clay Powder Benefits

  • Potent antioxidant properties
  • Rich in amino acids and nutrients
  • Rich in polyphenols and EGCG (ahem, works wonders on your complexion)
  • Slow ground using granite grinders retaining it’s maximum potency
  • Combined with natural kaolin clay to absorb oil, helps draw out impurities for skin that radiates and glows.

Seaweed Powder Benefits

  • Known for its renewing properties
  • Full of beneficial vitamins, powerful antioxidants, minerals, amino acids and trace elements
  • Nourishes, smooths, remineralizes and rehydrates skin
  • Sustainably harvested and carefully handled maintaining the plant integrity

Shiri was kind enough to send over both products to try, and I’m gonna level with you guys. I’ve been using this stuff the way I used to overdose on Sun-In while chillin’ next to my friend’s pool reading Seventeen Magazine back in 2005.

I’ve been making a simple face mask with the matcha clay powder and using it on my face about once a week, and I’ve been using the seaweed powder in the shower every few days. You could use either interchangeably. And! Here’s the fun part. You can mix and match with other ingredients to make a mask. Sometimes I use jojoba oil, sometimes I use coconut oil. Sometimes I use honey, and sometimes I just use water. Regardless of what type of oil I use (or if I use any at all), my skin always feels wonderful afterward.

Bonus: these containers are gigantic and since a small amount of powder goes a long way, these puppies will last forever.

DIY Seaweed MaskHow to Make a DIY Seaweed Mask or Scrub

Like I mentioned, you can just keep this in your shower and scrub all over wet skin for a detoxifying scrub, or you can create a face mask. One thing to note: this is the real deal and straight up smells like seaweed. I don’t mind it, because I’m used to walking my dog on the beach almost everyday. But if you’re sensitive to the smell, consider yourself warned. Once you get past that, I promise it’s really rad stuff.

Here’s a great recipe from 23 Skin:


  • 1 tablespoon raw honey
  • 1 tablespoon Seaweed Powder
  • 1 teaspoon aloe vera gel
  • warm water until you get the right consistency


Mix all ingredients and apply on a clean face. After 20 minutes, gently massage into skin before rinsing off for added exfoliation benefits. Follow up with your favorite moisturizer.

How to Make a DIY Matcha Mask

Ho boy I loooove this mask. It’s a new staple in my Self Care Saturday. It smells good and leaves my skin feeling amazing!

Here’s a great recipe from 23 Skin:


  • 1 tbsp Matcha Clay Powder
  • 1 tsp carrier oil (I used jojoba oil but you could use olive oil, coconut oil, argan oil or any other type)
  • Warm water or more oil for consistency (I used about half a teaspoon, you really don’t need much!)


  1. Mix in a bowl and smooth all over face with fingertips or a gentle brush. Leave on for 10-15 minutes and remove with warm water.
