Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Tetrahexyldecyl Ascorbate (THD) is a stable and oil-soluble form of Vitamin C.
THD is special in that it has the ability to travel deeper into skin than traditional ascorbic acid while maintaining the same skin benefits (double win!).
Because it’s oil-soluble, THD dives deep into your skin’s fatty layers (think ceramides and cholesterol) to fight off the kind of free radicals that mess with your skin barrier. This makes it a great pair with water-based vitamin C (ascorbic acid) that mainly works on the surface.
Even at just 0.1%, THD is already showing great antioxidant activity. When used up to 2%, it helps keep your skin happy and calm, especially when it’s stressed from pollution or sun.
Want to fade dark spots or tackle hyperpigmentation? You’ll want 5% or more. Pairing it with brightening buddies like niacinamide or licorice root gives even better results. One study even used 30% THD with other brighteners and saw real results on stubborn discoloration, even in melasma-prone skin.
A note on THD: It’s has a slightly silky, oily texture and usually shows up colorless or pale yellow (though the exact shade can vary by supplier).
While you can sneak it into water-based formulas, it really shines when paired with silicones or oils, which help your skin soak it up better.
THD is pretty stable, but it’s still vulnerable to degradation like ascorbic acid. Too much light or heat (above 113°F / 45°C) can break it down over time. Go for dark and opaque packaging that keeps it safe and shady!

So smooth
This is an excellent oil - very very lightly scented (almost smells like pickles but I am pregnant, so...) and goes on very smoothly. I use it at night for extra moisture before my moisturizer and I love it. The only downside is this price point is not affordable for me in the long-run, so when my sample runs out I'll be missing it.
Instantly fell in love with this oil. It's light weight, absorbs quickly, goes on smoothly, doesn't leave me feeling greasy, hardly any noticeable fragrance, and an excellent source of Vitamin C. I use it at night after my serum and before moisturizing. My skin feels so smooth, not irritated, and well hydrated in the morning. What more could you want? Oh, the price... yeah it is definitely more on Show more
