Main Ingredients:
- Glutathione: Provides powerful antioxidant care to help neutralize free radicals, clarifying the skin and reducing the appearance of dullness.

- Niacinamide: Improves overall skin tone uniformity by managing the flow of pigmentation rising to the skin’s surface, leaving a dark and dull complexion looking clear and even.

- Tranexamic Acid: Delivers targeted intensive care to specifically manage recurring local pigment concerns, such as stubborn dark spots and blemishes.

- Powered by SRGF H1 Complex: A patented ingredient integrating the technology of derma-skincare expert Medians, composed of skin and stem cell growth factors, placental growth factors, and complex peptides to awaken the skin’s inner energy for a strong, healthy barrier.

Formulation:
A refreshing, moisture-rich gel-type texture that absorbs rapidly into the skin to deliver active ingredients effectively without feeling heavy.

Triple Brightening Special Care
Targeted special care designed for localized areas with dark spots, blemishes, and hyperpigmentation.

How to use:
- After prepping your skin with toner, apply an even layer of the Triple Whitening Serum to your face, neck, and targeted areas like elbows.
- Gently pat the formula into your skin to maximize absorption. For best results, incorporate this step into both your morning and evening skincare routines as needed.
- Tip 1 (As a Nourishing Pack): Apply a thick layer over dull skin areas to use as a high-functioning brightening mask.
- Tip 2 (With Home Care Devices): Pair with your skincare device to effectively deliver energy to the skin and minimize irritation by reducing friction.
