Why Customise Your Serums?

IREN Shizen was founded as a modern re-envisioning of J-beauty, where we took traditional Japanese skincare rituals and integrated them with scientific solutions to create custom skincare, especially for you. There’s no such thing as a one-size-fits-all solution to our varying skin concerns. One product that has been gaining popularity in recent years is our customized serums. There are 7 custom serums which you can mix and match to create 35 possible combinations that cover all the different skin types and concerns in the world.

What is Customized Serum?
IREN Shizen customized serum is a skincare product that is specifically formulated to meet the unique needs of an individual's skin. Unlike generic serums, which are mass-produced and contain a standard set of ingredients, customized serums are created based on a person's skin type, concerns, and goals. They are tailored to address specific skin concerns, such as acne, aging, and dark spots, and to support overall skin health.

Addresses Specific Skin Concerns
One of the biggest benefits of customized serum is that it addresses specific skin concerns. For example, if you have acne-prone skin, a customized serum can be formulated to target the underlying causes of acne, such as inflammation and overproduction of oil. This can help to clear breakouts, reduce redness, and prevent future outbreaks. Similarly, if you have aging skin, a customized serum can be formulated with ingredients that help to boost collagen production, hydrate the skin, and improve skin texture and elasticity.

More Effective than Generic Serums
Customized serums are often more effective than generic serums because they are tailored to meet the specific needs of your skin. This means that the ingredients are carefully selected and blended to provide the maximum benefit for your skin type and concerns. In contrast, generic serums may contain ingredients that are not well-suited for your skin, leading to less effective results. For example, if you have sensitive skin, a generic serum may contain fragrances or alcohol that can irritate your skin. A customized serum, on the other hand, can be formulated without these potentially irritating ingredients.

Better Absorption and Penetration
Customized serums are designed to be easily absorbed and penetrate the skin, delivering the active ingredients where they are needed most. This is achieved by carefully selecting ingredients that are compatible with your skin, and by formulating the serum to have the right consistency and pH. The result is a serum that works more effectively to address your skin concerns.

Personalized Experience
Customized serum provides a personalized skincare experience. Not only are the ingredients tailored to meet your specific needs, but the serum itself is also customized to your preferences. For example, you may prefer a lighter or heavier texture, or a serum that is scented or unscented. With customized serum, you can choose the ingredients, texture, and scent that work best for you, resulting in a truly personalized skincare experience.

Supports Overall Skin Health
Finally, customized serum supports overall skin health. By targeting specific skin concerns and supporting overall skin health, a customized serum can help to improve the overall health and appearance of your skin. This, in turn, can lead to a more radiant and youthful-looking complexion.

In conclusion, IREN Shizen custom serum is a superior option for anyone looking to improve their skin health and address specific skin concerns. With its ability to target specific skin concerns, provide better absorption and penetration, offer a personalized experience, and support overall skin health, customized serum is the future of skincare.
