Yes, it is perfectly safe for daytime use, provided you follow up with a broad-spectrum sunscreen.

Yes, it has been dermatologically tested; however, a patch test is recommended for those with known sensitivities.

With daily use of 2-3 drops, one bottle typically lasts between 4 to 6 weeks.

No, this is a treatment ampoule and should be followed by a standard moisturizer to lock in hydration.

It is generally recommended to alternate them—using Vitamin C in the morning and Retinol in the evening—to minimize potential irritation.

Ensure the cap is tightly closed and the bulb is fully depressed before inserting it into the bottle to create a proper vacuum seal.
