THE FORMULA

Your skin’s daily defense against dullness, damage and premature signs of aging. This high-performance serum brightens, firms, plumps and strengthens skin while neutralizing daily environmental stress.

Powered by vitamin C and three clinically-proven peptides, this serum promotes a firmer texture and increases skin's elasticity by supporting collagen, brightens dark spots and dullness, reduces the appearance of fine lines and wrinkles, and helps neutralize free radicals. Its advanced humectants draw water into the skin, so skin is more luminous and hydrated all day. With daily use, skin is supple, radiant and resists premature signs of aging.

  • Gentle and safe for all skin types, especially dull and aging
  • Light, silky, fast-absorbing texture
  • Free of fragrance and essential oils
  • Skin-friendly pH 5.0-5.5

A daily multivitamin for your skin

The hero product of our line, Active Hydration consistently delivers skin that looks healthy, awake and well cared for.

Like a daily multivitamin for skin, this lightweight, fast-absorbing serum fits effortlessly into your routine, giving skin what it needs to stay balanced, comfortable, and resilient throughout each day while helping skin resist premature aging.

Get ready to notice a more luminous complexion that's natural, radiant and alive.

How to use

To get the best effectiveness from your serum, we recommend first misting clean skin with Healing Water Toning Mist. Skin is more receptive to active ingredients when it’s already moist and primed for absorption.

Next, dispense several drops of serum into your cupped fingertips, and apply by smoothing evenly onto all parts of the face and neck.

For best results, lock in the hydration by following this serum with Precious Oils Active Infusion.

Customers praised this vitamin C serum for making skin "soft and supple" with noticeable brightness and even tone. Shoppers loved the "cleanest vitamin C serum" available, noting improvements in skin texture and reduced signs of aging. The eco-friendly refill option was appreciated. All reviews were 5-star ratings with zero complaints.

Love!!

I started off with the travel/trial set to try out a variety of products and after the first week I was obsessed! Activist Skincare is exactly what I was looking for when it came to high-quality products and sustainability. After a few simple questions I was able to set up a convenient subscription to fit my needs based off how often I would be using each product. They also go above and beyond with the packaging and even go as far to leave a handwritten note inside the box. I would 100% recommend to anyone looking to change up their skincare routine with sustainable products.

The only Vitamin C that doesn’t irritate me

I was scared to try this because every vitamin C I tried in the past gave me skin flare ups. This one did not. I’ve been using it daily two weeks now and so far so good 👍 I’m looking forward to seeing what longer term results will be.

The product is great. I love that it’s environmentally friendly and my skin is happy too. But it is nothing too special considering the price.

Lighter Oil - Great for Daily Use

I have tried at least 10 different facial oils from a variety of luxury brands and this one is the one I keep reaching for. I find that only 5 drops gives me a full face of moisture that doesn’t sit on top of the skin but soaks in quickly. Instead of needing layers of moisture and hydration, this oil leaves my skin feeling plump and healthy.

Chefs Kiss!

I received my order quickly and it was perfect. I am now enjoying all the yummy items. The tinted spf stick was an impulse try-buy, and it might be my fav of the bunch! The medium tint is a perfect match skin, coverage is great, and a dynamite size for on the go touch ups!

Love this product!

I took a chance on the face oil, because I'm trying to get rid of plastic bottles and hoped I would like it. And, the product is great - goes on easily, absorbs easily and makes my skin really soft. A bonus that it came quickly and no plastic packaging!
