How strong is the vitamin C?

It uses 20% L-ascorbic acid, a high concentration compared with many vitamin C serums. That makes it effective for brightening but potentially irritating for sensitive skin.

Apply 5 to 7 drops to clean skin, then follow with moisturizer and sunscreen. Vitamin C works best in the morning under sun protection.

How long does it last after opening?

Use it within 3 to 6 months of first opening and store it below 25°C (77°F). L-ascorbic acid oxidizes over time and turns yellow-brown.

Is it good for sensitive skin?

It is formulated for normal to oily skin, and 20% L-ascorbic acid can sting reactive skin. Patch test first if your skin is sensitive or dry.

What results can I expect?

The brand reports improved radiance within 4 weeks and smoother skin for 90% of participants within 8 weeks. Results vary by skin type.
