Step 2 Soffli 16% Vitamin C Serum

$38

This pH-adjusted 16% Vitamin C Serum helps reduce the look of sun spots and hyperpigmentation, leaving your skin looking bright, firm and smooth. Our secret is using a blend of potent antioxidant-rich Vitamin C (pure Ascorbic acid and stable 3-O-Ethyl Ascorbic acid) at 16%, along with a proprietary blend of short, medium and long-chain hyaluronic acid molecules to deeply hydrate your skin at every level. To that we add ferulic acid and vitamin E which help leave your skin looking dewy and radiant.

It comes in a slightly yellow and silky texture, so more substantive than water but lightweight and easily absorbed and not sticky for a Vitamin C serum.

Size: 30 ml

When it comes to proven skincare ingredients, you can’t leave out Vitamin C, praised for its powerful antioxidant benefits and known to protect against oxidative stress to keep your skin looking firm, smooth and bright. The main issue when it comes to Vitamin C is that it can be highly unstable and rendered ineffective even before it hits your skin! 

We’ve found that combining two different forms of Vitamin C (pure Ascorbic acid with the more stable 3-O-Ethyl Ascorbic acid) at a concentration of 16% is the best way to deliver a potent and stable dose of Vitamin C to your skin without irritation. 

Dr. Yoon says, “although higher concentrations of Vitamin C in skincare can we powerful, it often comes with irritation or sensitivity issues – it’s great that this serum has been formulated at a high 16% Vitamin C percentage but also with a focus on stable and gentle delivery.”

All of the ingredients used for this serum are scored by the EWG (a non-profit that rates the toxicity of ingredients found in skincare) as 1-2, which is the lowest toxicity rating they give out.

  • 3-O-Ethyl Ascorbic Acid is known to be a very stable and effective form of skincare superstar, Vitamin C, proven to help with hyperpigmentation and boost collagen. EWG score 1.
  • Propanediol is a solvent that helps dissolve ingredients and also functions as a humectant and emollient to add moisture to your skin and reduce moisture loss. EWG score 2.
  • Butylene Glycol is a humectant, solvent, and emollient that helps skin retain moisture, dissolves ingredients, and improves the application experience. EWG score 1.
  • 1,2-Hexanediol is a non-sensitizing preservative commonly found in clean beauty products that helps keep products safe and fresh. EWG score 1.
  • Ascorbic Acid is the most well-researched and pure form of skincare superstar, Vitamin C, proven to help with hyperpigmentation and boost collagen. EWG score 1.
  • Hydroxyethylcellulose is a plant-derived texture enhancer that makes products easier to apply. EWG score 1.
  • Sodium Hyaluronate is the salt form of hyaluronic acid. It’s a powerful humectant that binds up to 1,000x its own weight in water and penetrates deeper into skin than pure hyaluronic acid. We use a proprietary blend of short, medium and long-chain molecules; short-chains sink into deeper layers of the skin, medium-chains fill in the layers closer to the skin surface, and long-chain molecules lock in moisture on the top so that your skin is deeply hydrated and plumped up at every level. EWG score 1.
  • Citric Acid is a pH adjuster and also an AHA. EWG score 1-2.
  • Ferulic Acid is a plant-based antioxidant that has been shown to enhance the stability of Vitamins C and E. EWG score 1-2.
  • Tocopherol, also known as Vitamin E, is one of the most well-known and researched beneficial antioxidants for your skin. EWG score 1.
  • Ethylhexylglycerin, derived from glycerin, helps soften skin and enhances the effectiveness of preservatives. EWG score 2.
  • Coptis Japonica Root Extract extracted from the root of a traditional East-Asian medicinal herb, is known for its anti-inflammatory, antioxidant and antimicrobial properties. EWG score 1.
  • Trisodium Ethylenediamine Disuccinate is a chelating agent that improves the efficacy and stability of preservatives and antioxidants. EWG score 1.

Immediately after Step 1 Toner (or directly after cleansing), take 1-2 pumps into hands and in upward gentle strokes or light pats, apply from neck to edges of the face.  

Move on to moisturizer, 1-2 minutes after so you give the serum enough time to absorb. Use this time for quick meditation to tell yourself how amazing you are!  

We’ve obsessively formulated it so that it should be gentle enough for daily use, but if you have sensitive skin or otherwise feel irritation, consider using 2-3 times/week just in the morning and build up from there. Always use sunscreen as part of your daytime skincare routine. 

We recommend you store in a cool, dry place, out of sunlight - a cosmetics fridge or wine fridge are great ideas to preserve maximum potency of Vitamin C!

Sunspots are gone...

...since I started using this serum. I noticed the difference in just a couple of days of using it but I really noticed the difference when I stopped using it. The sunspots were back. Besides that, I will second what some other reviewers have said about the feel of the serum and the no fragrance. I really like that!

Great Vitamin C Serum - works and made well!

It works well for brightening my skin and also love that it is stored in a dark container - this is crucial I'm told for keeping it fresh! Highly recommend.
