Eating salmon is healthy for your health, but salmon sperm can be the secret of youthful complexion. I am referring to the DNA extracted from salmon sperm, which has found its way into the luxurious skincare world. Meet Rejuran!
Rejuran is an injectable for skin healing that has grown in popularity in the past few years. It contains purified salmon sperm DNA, also known as polydeoxyribonucleotide (PDRN). Before Rejuran, skin boosters were the most common type of aesthetic treatment. Rejuran is also usually called Rejuran Healer, PN, PDRN Therapy, Miracle Healer Injection, or 婴儿针 (Baby skin injections). Wondering how sperm from salmon can contribute to your beauty? Here’s 3 reasons why:
1. Skin elasticity
Research was done to examine the impact salmon DNA taken from salmon sperm on human skin. The effects were shocking. Subjects demonstrated a significant increase in skin elasticity, texture, and hydration by applying salmon DNA on human skin [1].
The research, which was performed over 12 weeks, revealed that after the fourth week the DNA increased skin elasticity more than the control cream. It also found that the DNA reduced water loss and increased water content in the skin.
Salmon sperm DNA application also improved the ability of the skin to produce hyaluronic acid itself.
2. Wound healing
In 2016 and 2018, two different studies found that salmon sperm DNA contains wound healing abilities [2] [3].
One of the main reasons it is such a great healer is that it helps the development of blood vessels. This adds to a thicker layer on the skin that is more resilient to irritation.
3. Sunscreen
Sunscreen was made in the 20th century from a range of materials. Early materials used in sunscreen were thick substances such as zinc oxide, or the world war II’s “red vet pet” jelly, which effectively shielded the skin from rays of the sun. Forms later blended with coconut oil and other materials to make the sunscreen more comfortable and easy to use when covering our bodies.
Rejuran also has the potential to reverse UV damage. And the more you are exposed to the salmon sperm DNA, the more it protects your skin from ultraviolet light.
In fact, a result of a laboratory analysis found that salmon sperm effectively blocked 90% of UVB rays and up to 20% of UVA rays [4].
Conclusion
Are you ready to inject salmon sperm DNA to your skin? As we have learned, it is full of great benefits for you. If you still have concerns about Rejuran you can bring it up to your aesthetic doctor. I wish you well on your skincare journey!
