Patented formula, impossible to replicate
The patent of the Duke family lies in the precise blending of 15% L-ascorbic acid (pure vitamin C) + 1% vitamin E + 0.5% ferulic acid at an optimal pH level. This formula not only provides up to 8 times more natural skin antioxidant protection, but also stimulates collagen regeneration and reduces damage from photoaging. 
✨ Effect Verified by Clinical Trials 
Brighten skin tone: Significantly reduces melanin production, improves dullness, and makes the skin smooth and radiant. 
Reduce wrinkles: Use continuously for 12 weeks, and visible wrinkles such as crow's feet and glabellar lines will be reduced. 
Powerful protection: Neutralizes free radicals and defends against oxidative damage caused by ultraviolet rays and environmental pollution. 
 Scientific usage, achieving twice the result with half the effort
Use as a daytime essence. After cleansing and after drying hands and face, drop 4-5 drops onto the palm, and press onto the face and neck. Be careful not to touch the eye area. Then, it is necessary to apply a sunscreen product to achieve the best protection effect. 
Target audience: Suitable for all skin types (including those with good tolerance of oily skin/combination oily skin), especially for people with dull skin, those who have anti-aging needs, and those who frequently come into contact with computers, mobile phones and urban pollution.
