Super Drop C

Super Drop C — Vitamin C Serum for Sensitive Skin

30ml / 1 fl oz

Why everything you have been told about vitamin C is only half the story

I have sat across from more clients than I can count who said the same thing to me.

"I tried vitamin C. It burned. It broke me out. The bottle turned orange in three weeks. I gave up."

And every time, I thought the same thing: we are selling this ingredient completely wrong.

Every brand will tell you vitamin C is an antioxidant. And it is. But that is not its function in skin that matters most — and leading with it is exactly why 99% of vitamin C products on the market are missing the point.

Vitamin C is the essential biological cofactor to collagen production. That is the story. Without adequate vitamin C, the fibroblasts in your dermis cannot synthesize collagen. Not less collagen. No collagen. It is not a glow ingredient. It is not optional. It is the signal your skin's collagen-building cells are waiting to receive.

We reduced it to a brightener. We put it in water-based formulas that oxidize within weeks, sit on top of the skin because water cannot cross a lipid barrier, and sting and inflame the very people who need collagen support most — women with rosacea, eczema, and chronically reactive skin who were told they simply could not use actives.

I formulated Super Drop C because I was done with that story.

What Super Drop C does

Super Drop C delivers vitamin C where it has always needed to go — past the barrier, into the dermis, to the fibroblasts that build collagen — without inflammation, oxidation, or irritation at the surface.

With consistent use, skin becomes visibly firmer. Tone evens out. Post-inflammatory hyperpigmentation fades. Fine lines soften not because anything has been resurfaced, but because the structural foundation beneath them is being actively rebuilt.

It absorbs without residue. It does not sting. The formula does not oxidize in the bottle. And it works on skin that other vitamin C formulas have already failed — because it is not fighting the barrier to get inside it.

The Korean priori science behind the formula

THD Ascorbate — tetrahexyldecyl ascorbate — is the reason this formula does what water-soluble vitamin C cannot.

The skin's barrier is lipid-based. Standard L-ascorbic acid is water-soluble. It cannot cross. It knocks on a door that was never going to open — sitting at the surface, oxidizing, causing the stinging and breakouts that made you give up on vitamin C in the first place.

THD Ascorbate is oil-soluble. It speaks the skin's language. Developed through Korean ingredient science and its exacting approach to bioavailability, it penetrates the lipid barrier and travels to the dermis — the layer where fibroblasts live and where collagen synthesis actually happens. It converts to active ascorbic acid only once it arrives at the target site. Zero oxidation in transit. Zero irritation at the surface. Full activity where it counts.

This is the Korean priori approach: not chasing trends, not reformulating a compromised ingredient to fit a water-based texture. Choosing the form of the ingredient that the skin's own biology will actually accept.

Gentle but giant: 60% THD Ascorbate, and why Astaxanthin changes everything

At 60% concentration, THD Ascorbate is not a supporting ingredient in this formula. It is the formula.

Most vitamin C products on the market — even those positioned as high-performance — use concentrations well below what research shows is needed to meaningfully reach the fibroblasts and support collagen synthesis. We did not dilute it. We did not dress a trace amount in marketing language. The concentration is the point.

And then there is Astaxanthin.

Most brands pair vitamin C with other antioxidants to amplify its antioxidant effect. We did the opposite — and it changes what this formula is capable of.

Astaxanthin is a marine carotenoid derived from microalgae. It is 6,000 times more potent as an antioxidant than vitamin C. It is what gives wild salmon their cellular endurance. In skin, it neutralizes free radical damage at a depth most actives never reach.

When you give Astaxanthin the antioxidant job, you free THD Ascorbate to do the one thing no other ingredient can replace it for: getting to the fibroblasts and telling them to build collagen.

That is the division of labor that makes this formula different. Not two antioxidants stacked on top of each other. One antioxidant doing what it does better than anything else on earth — so that vitamin C can finally do what it was always biologically meant to do.

For my clients with rosacea, eczema, acne, and chronically reactive skin — this is the formula I reach for first. Not because it is gentle in spite of being powerful. But because it is gentle because it understands the skin deeply enough not to fight it.

Transform without traumatizing. That is the standard this formula was built to meet.

How to use Super Drop C

Apply 3 to 4 drops to clean, dry skin each morning before moisturizer and SPF. Press gently into face and neck — do not rub.

If you are new to vitamin C or have reactive skin, begin on alternating days and increase to daily use as your skin adjusts.

Do not layer with direct acids or retinol in the same routine step. Super Drop C works best as the first active applied to bare skin, followed by a barrier-supporting moisturizer and broad-spectrum SPF 30 or higher.

Store away from direct sunlight. Unlike water-soluble vitamin C, THD Ascorbate is stable — but cool, dark storage extends the life of every active in the bottle.
