Questions about MK20?
8 frequently asked questions about MK20
What is MK20 eye cell nutrition spray?
Answer:MK20 is a spray product for daily eye care, suitable for maintaining eye health, reducing eye fatigue, and improving vision disorder concerns. It does not replace ophthalmic diagnosis, prescription medicine, or surgical treatment; if you have persistent pain, redness, sudden vision changes, or a diagnosed eye disease, please consult an eye care professional first.
Can I use MK20 if I have high eye pressure?
Answer:Yes. Eye pressure testing is a routine ophthalmic check and an important indicator for screening glaucoma. When a doctor performs this check, it is to assess whether you may have glaucoma. If increased eye pressure causes you to see colored halos when looking at lights, it means you should begin paying attention to eye function. Try to rest your eyes more and avoid overusing them. Spray MK20 eye nourishing water 10–30 times daily, and try to prevent glaucoma symptoms as early as possible.
Can I use MK20 while wearing contact lenses?
Answer:Yes. MK20 eye nourishing water can be used while wearing contact lenses because the molecules in MK20 eye nourishing water are very small and fine. They penetrate into the eye cells in about 1–3 seconds, so users can use it with confidence.
Can I use MK20 if my eyes often become red?
Answer:Yes. Red eyes are usually caused by dryness, allergies, or tiredness, and may be a sign of conjunctivitis caused by bacterial or viral infection or a combination of these factors. Spray MK20 eye nourishing water up to 20 times daily until the redness subsides.
What are the ingredients in MK20?
Answer:MK20 does not contain any chemical additives, preservatives, or fragrance. The eye nourishing water is 100% pure natural water and contains more than 20 natural trace element compounds, including these 4:
Selenium - used to strengthen the immune system and resist infection, reducing free radicals that may damage the eyes;
Zinc - protects tissues and strengthens eye cells;
Magnesium - helps nerve conduction, expands blood vessels, and maintains blood flow to the eyes;
Copper - produces collagen, a component of connective tissue, and maintains healthy cell membranes.
Who is MK20 suitable for?
Answer:Anyone of any age can use MK20 eye nourishing water. It is especially suitable for office workers, teenagers, people with eye concerns, heavy mobile phone users, computer users, people who stay up late, and drivers.
How many times a day should I spray MK20?
Answer:For eye fatigue, eyelid inflammation, dark circles, and eye bags, spray 20 times daily. You can also spray cold MK20 onto a thin piece of cotton and apply it to the eyes for 10 minutes, once in the morning and once at night. Once these problems subside, spray 5–10 times daily to maintain eye health.
How does MK20 work?
Answer:Through quantum molecular technology processing, MK20's water molecule clusters become smaller, and the important trace elements contained in the water are released. Through spraying, MK20 provides water molecules and trace element compound nutrients that go deep into your eye cells. When eye cells begin to absorb water and nutrients, the eyes also become healthier. During the process of becoming healthier, your eye cells begin to detoxify, repair, rebuild, and regenerate cells until their natural healthy function is restored.
