Vitamin C in its purest form - L-ascorbic acid - is one of the most powerful ingredients in skincare, but also one of the most fragile. From the moment it’s bottled, L-Ascorbic Acid (Vitamin C) begins to degrade, losing its effectiveness over time, especially when exposed to air, light, or heat. 

So Vitamin C serums that have been sitting in warehouses for months, sometimes longer, before they ever reach you may have already lost much of their potency.

At DrLOUIE, we already use a superior, scientifically-stabilized formula — 20% pure L-Ascorbic Acid at below pH 3.4, paired Emblica™ to enhance stability and antioxidant performance, bottled in a superior UV protective black bottle. But we wanted to go even further. Because no matter how good the formula, Vitamin C works best when it’s fresh.

That’s why we created Fresh Drop™.

Fresh Drop™ is our promise to deliver peak potency skincare — fresh from our lab to your skin. Here’s what it means:

• Small Batches, Produced Frequently: Instead of making huge batches to last for weeks and months, we manufacture in small quantities, more often, so that the Vitamin C Serum you receive is as fresh as possible.

• Never Warehoused Long-Term: We never let our Vitamin C Serum sit in a warehouse for months on end. Each batch is shipped out soon after bottling — not stockpiled.

• Lab-to-Skin Delivery: From our family-owned lab directly to your hands, bypassing unnecessary delays that compromise freshness.

This philosophy is inspired by how premium extra virgin olive oil (EVOO) is produced and enjoyed. 

When EVOO is freshly pressed, it’s vibrant, full of antioxidants, and delivers maximum flavor and health benefits. But over time — even in a sealed bottle — those antioxidants degrade, and the oil becomes flat and less effective.

Vitamin C works the same way. 

When freshly bottled, it’s at peak potency, with strong antioxidant activity to brighten, protect, and repair your skin. But if it sits on a warehouse shelf for months, the vitamin C begins to oxidize and lose its power long before you open the bottle.

Just as food connoisseurs seek out freshly pressed olive oil for its superior quality, we believe your skin deserves the same level of care — fresh, potent, and full of life.

We don’t just tell you when to use it by — we show you when it was made. 

Every bottle of DrLOUIE Vitamin C Serum is date-stamped with the exact manufacturing and bottling date, and you can also see this information clearly on our product page before you buy.

This way, you always know just how fresh your serum is — no guessing required.

To celebrate summer — and our latest FreshDrop™ batch — we’re offering free shipping on all Vitamin C Serum orders placed in July. 

There’s never been a better time to experience peak potency skincare, fresh from our lab to your skin.
