Kiehl's Launches Innovative Rare Earth Serum Primer

Kiehl's, a renowned skincare brand founded in 1851 in New York’s East Village, has introduced a new skincare product, the Rare Earth Serum Primer. Set to hit the shelves on February 27, 2026, this innovative product is designed to tackle shiny skin and dryness, integrating hydration-focused benefits into its formulation. Available online from February 20, the primer represents a new step in the evolving landscape of skincare tools that not only enhance makeup application but also contribute to the skin's health.

A Blend of Science and Nature

Kiehl's has long been known for its commitment to using natural ingredients derived from the earth, and the Rare Earth Serum Primer follows this tradition. It incorporates unique elements such as Amazonian white clay, which has been an essential part of Kiehl’s acclaimed Rare Earth Mask series. This fine clay effectively absorbs excess oil, targeting shiny spots and minimizing the appearance of pores.

The primer appeals to modern skincare consumers who are increasingly aware of the need for products that marry beauty with skin health. The formulation not only helps control shine but also hydrates the skin's surface, creating a light and even moisture-retaining layer, often referred to as the “urusaura veil.” This novel texture offers a refreshing feel that keeps the skin looking fresh and comfortable throughout the day.

Spring-Ready Skincare

As spring approaches, many experience a shift in their skin due to changes in temperature, pollen, and increased UV exposure. The Rare Earth Serum Primer’s lightweight texture seamlessly adapts to these seasonal challenges. By offering a unique blend of hydration and shine control, the primer is particularly suitable for those who struggle with skin sensitivity or dryness during the spring months, providing an ideal solution to maintain skin balance.

Key Features of Rare Earth Serum Primer

1. Effective Shine Control

The primer incorporates a special white clay that is known for its oil-absorbing properties. This ingredient keeps the skin matte without compromising hydration. It can even be applied over sunscreen, making it versatile for various makeup routines.

2. Dual Action: Exfoliation and Hydration

In addition to clay, the primer includes LHA (Lipid Hydroxy Acid), which gently aids in smoothing rough skin texture while holding moisture. Notably, beta-glucan, a potent hydrating agent, provides superior moisturization, enhancing the skin’s barrier function to tackle common concerns related to mixed or dehydrated skin types.

3. Backed by Years of Research

With 175 years' worth of dermatological expertise, Kiehl's has carefully crafted this primer to provide up to 12 hours of oil control and hydration, ensuring your skin feels fresh all day long.

Kiehl's is dedicated to enhancing customer experiences and building a supportive community. Their commitment to quality and sustainability is reflected in the introduction of this new product, embodying the values established by founder Aaron Morse: nature, science, and service.

How to Use the Rare Earth Serum Primer

1. After regular skincare, take a pearl-sized amount of the primer and dot it across your face.
2. Gently spread it evenly, focusing on the T-zone, as well as areas known as the “butterfly zone,” including the cheeks and around the nose.
3. Allow the primer to absorb fully before applying sunscreen or makeup, allowing for an even smoother application.

Recommended Pairing for Enhanced Results

To complement the Rare Earth Serum Primer, Kiehl’s Blue Herb Peel Serum can be introduced into your routine. This serum focuses on cleansing rough texture and minimizing pores while being gentle enough for sensitive skin. It sets the stage for the primer application, ensuring skin that feels as good as it looks.

Kiehl’s products are sold at their retail locations and on their official online store, with the Rare Earth Serum Primer priced at 4,950 yen for a 30mL bottle.
