how to use

1. Dispense 3-4 drops of the product and gently massage or tap it into the skin until fully absorbed.

2. Follow with a moisturizer to lock in the hydration.

Daytime Use: You can use this product during the day.However, we strongly recommend applying sunscreen on top of the Vitamin C to
protect your skin from UV damage.

Avoid Mixing with Other Actives: Do not use this product in conjunction with chemical exfoliants such as AHA, BHA, or retinoids to prevent
potential irritation.

Potency and Freshness: This serum contains pure ascorbic acid (Vitamin C), so it's best to use
it immediately after purchase to maintain its effectiveness.

Storage: Store the product in the refrigerator before and after opening. Vitamin C is sensitive to changes in temperature, light, and air. To preserve its potency, keep it in a refrigerator or in a cool, dark, and dry place.

Initial Reaction: You might experience mild tingling or redness when you first start using Vitamin C, especially if it’s a high concentration. This is normal but should subside as your skin adjusts. If irritation persists, you should discontinue use.

Skin Sensitivity: If you’re new to Vitamin C, start with a small amount to see how your skin reacts. Gradually increase the amount as your
skin builds tolerance.
