Introducing breakthrough solution for hair thinning and loss in men and women. CosmeRNA’s unique formula containing SAMiRNA, manages male and female pattern baldness. It improves hair loss caused by Androgenetic Alopecia in men and women by maintaining the hair follicle cells healthier, resulting in thicker, fuller hair.

How to Use

Apply once every 2 weeks.*
Visible improvements observed after 4 to 6 months of use.**

* Usage frequency may vary depending on the severity of hair loss conditions.
** Regular application recommended with efficacy subject to individual variation.

It's not Magic. It's Science.

We believe in the power of innovation and continued research to adhere hair loss concerns for Androgenetic Alopecia. CosmeRNA’s unique formula employing RNA interference technology alleviates male and female pattern baldness by selectively suppressing the expression of androgen receptor.

Patented Technology

Employing Nobel Prize-winning RNAi technology, CosmeRNA Anti-Hair Loss Tonic brings a breakthrough solution that makes actual changes.

How it works

Traditional hair loss medications inhibit 5a-reductase thereby acting as DHT blockers, often accompanied by numerous side effects.
CosmeRNA specifically targets to suppress the Androgen Receptor expression without inhibiting systematic DHT synthesis.


Key Ingredients

How to use

1. After shampooing, make sure the scalp is completely dry before application.
2. Part your hair using a comb to expose the affected area.
3. Place the silicone tip directly onto the affected area of the scalp. Make sure the tonic targets the hair follicle, not the hair itself.
4. Gently squeeze the plunger and apply an appropriate amount to the scalp to prevent dripping.
5. Actively massage your scalp with the tip using a front-to-back motion for 30 seconds.
6. Repeat Step 4,5 and 6. Evenly spread the tonic and massage throughout the affected area of the scalp, section by section.
After Use
7. Always lock the product after use to avoid leakage.

Frequently Asked Questions

Q. What is CosmeRNA™ and how does it work?

CosmeRNA™’s story began with a team of dedicated scientists and researchers at Bioneer and siRNAgen since 1992 and is based on RNA & DNA technology.

The active ingredient of CosmeRNA, “SAMI-RNA AR68 (INCI Name: Stearyldisulfidehexyl DNA-2-PEG-45/SH-RNA-1) is designed to specifically and selectively inhibit the expression of AR in hair follicle cells which cause or exacerbate androgenetic alopecia.

Q. Should I be concerned with side effects?

Side effects are not present as proven in our clinical trials. CosmeRNA™ was awarded a 5-star safety rating by Dermatest, an independent skin safety testing lab, and multiple clinical studies in Korea and Germany have confirmed its safety for men and women.

Q. Can I use the product in combination with prescription hair loss medications

Our product acts on a unique mechanism in the hair follicle and is offered for the first time. CosmeRNA™ anti-hair loss tonic may be used as part of a regimen with other hair loss medications. Please consult your healthcare provider before using CosmeRNA™ with other hair loss medications.

Q. What is the action mechanism of CosmeRNA™?

Overall, the action mechanism of CosmeRNA™ likely involves the use of siRNA molecules, which is expensive as 300USD/mg to specifically targeting AR mRNA in the hair follicle using siRNA molecules.

The pathogenesis of AGA remains largely unknown. However, one study shows that in dermal papilla of the balding scalp in patients with AGA, nuclear localization of AR is elevated.

Thanks to research and development on RNA & DNA technology of Bioneer and SiRNAgen, we are able to develop and provide RNA anti-hair loss solutions at a reasonable price.
In our clinical study, main ingredient “SAMi-RNA AR68 (INCI Name: Stearyldisulfidehexyl DNA-2-PED-45/SH-RNA-1) helped to suppress the expression of AR to result in reduced binding of DHT, known as main cause of androgenic alopecia

Once the siRNA molecules are delivered to the hair follicle cells, they bind to complementary mRNA molecules and trigger RNA interference. This process causes the mRNA molecules to be degraded and prevents them from being translated into the proteins that contribute to AR production.

Reduction of AR levels: As a result of RNA interference, the expression of AR is effectively suppressed. This is expected to slow down the hair loss process in individuals with androgenic alopecia.

Q. How long does it take to see results from using CosmeRNA™?

We recommend to use it at least 4 months to see the result.

Q. How often should I use CosmeRNA™ products? Can I get more prompt effect if I use it more frequently?

Based on the clinical studies that show using CosmeRNA™ once every two weeks is similarly effective as using it once a week, we recommend use once per 2 weeks. For any further questions, please consult with a healthcare professional or a dermatologist, especially if you have any underlying medical conditions or are currently taking any medications.

Q. Is this product a medical product?

It is not a medical product but the world's first RNA anti-alopecia cosmeceutical product developed by more than 30 years of scientific research on RNA & DNA technology.
