Kinetin is a cytokinin. Cytokinins are compounds that stimulate plants to grow. Kinetin is used to make medicine.
People apply kinetin directly to the skin to reduce the effects of skin aging including roughness, fine wrinkles, dilated blood vessels, and uneven pigmentation.
Kinetin is sometimes applied to the skin in combination with retinol palmitate to treat signs of aging.
How does it work?
Kinetin prevents green plant leaves from turning brown. There is some information that suggests kinetin might prevent age-related changes in human skin by protecting the DNA in skin cells from damage (antioxidant effects) and decreasing skin water loss.
Insufficient Evidence to Rate Effectiveness for...
- An inner ear disorder called Meniere's disease. Early research suggests that filling the small cavity surrounding the middle ear bones with a solution of kinetin and the drug lidocaine improves symptoms such as hearing loss, ringing in the ear, and dizziness in many people with Meniere's disease.
- Reducing the signs of skin aging.
- Skin roughness.
- Fine wrinkles.
- Skin imperfections.
- Other conditions.
Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, and Insufficient Evidence to Rate (detailed description of each of the ratings).
Bleeding disorders: There is some concern that kinetin might prolong bleeding time and increase the risk of bruising and bleeding in some people with bleeding disorders. If you have a bleeding disorder, use kinetin with caution.
Surgery: Kinetin might increase the risk of bleeding during and after surgery. Stop taking kinetin at least 2 weeks before a scheduled surgery.
Medications that slow blood clotting (Anticoagulant / Antiplatelet drugs)Interaction Rating: Moderate Be cautious with this combination.Talk with your health provider.
Kinetin might slow blood clotting in some people. Taking kinetin along with medications that also slow clotting might increase the chances of bruising and bleeding in some people.
Some medications that slow blood clotting include aspirin, clopidogrel (Plavix), diclofenac (Voltaren, Cataflam, others), ibuprofen (Advil, Motrin, others), naproxen (Anaprox, Naprosyn, others), dalteparin (Fragmin), enoxaparin (Lovenox), heparin, warfarin (Coumadin), and others.
The appropriate dose of kinetin depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for kinetin. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
