This is part II of our series The Science of Skin Longevity. Find part I here.

When asked what three daily practices she'd have every patient commit to for skin longevity, Dr. Erika Klemperer recommends starting with a simple foundation: "Honestly, bringing it back to the very basics: sleep, exercise, and eating well. I know that sounds boring, but those foundational pillars really are essential. Once those practices are established, we can then begin to layer additional rituals."

The skin mirrors systemic aging, which means the factors that support your overall healthspan directly impact your skin's healthspan. Sleep enables cellular repair. Exercise enhances circulation and mitochondrial function. Nutrition provides the raw materials for every cellular process, from collagen synthesis to antioxidant defense.

"How we eat, move, sleep, stress, connect, love… it all deeply matters," Dr. Klemperer explains. "We all want to feel good, however there's no quick fix, no magic supplement or serum. Just a daily commitment to living our lives to their fullest."

1. Nutrition: Dr. Klemperer recommends "a whole-foods, plant-strong diet, rich in antioxidants, fiber, and healthy fats—a classic Mediterranean-style approach." The focus is on abundance rather than restriction: more vegetables, more variety, more color. Limit processed foods, refined sugars, refined carbohydrates, and alcohol where possible. Hydration is equally critical, supporting every cellular process from barrier function to cellular communication.
2. Environmental Protection: UV light is "the most powerful environmental stressor to the skin," but smoking, air pollution, blue light, extreme temperatures, dust, and mold all contribute to accelerated aging. Minimize exposure where possible through behavioral choices. Additionally, Dr. Erika Klemperer recommends daily SPF use to her clients, particularly the Every Tone SPF 30 for its “broad spectrum protection without the horrible white cast, blending seamlessly into all skin types.”

Translating the science of skin longevity into topical products requires a sophisticated understanding of cellular processes and ingredient efficacy. The goal is to remove impediments to healthy aging while providing key support for the skin's natural regeneration—working with the skin's innate intelligence rather than against it.

1. Antioxidants: Antioxidants play a vital role in this framework. Oxidative stress, driven by reactive oxygen species (ROS), contributes to cellular damage and accelerates aging. However, as Dr. Klemperer emphasizes, balance is essential: "It's essential to remember that oxidative stress also serves as a key cellular signaling mechanism and plays an important role in longevity. The goal isn't to eliminate ROS, but to maintain a dynamic equilibrium—the 'redox Goldilocks zone.'"
2. Natural Ingredients: "Nature is wildly elegant and natural ingredients can be highly sophisticated," Dr. Klemperer explains. She recommends ingredients like Vitamin C, i.e., Kakadu Plum found in the Essential Moisturizer,  and carotenoids like Astaxanthin, found in the Regeneration Mist. 

Beyond individual ingredients, the most effective longevity-focused formulas eliminate potentially harmful compounds and prioritize bioavailable, skin-compatible ingredients that support barrier function, provide antioxidant protection, and deliver the nutrients the skin needs for optimal cellular function. These formulations aren't quick fixes—they're tools for the long game of skin health.

Dr. Klemperer's framework for longevity skin care is direct: "I would recommend an antioxidant-rich product (i.e. Vitamin C serum or cream) along with a mineral-based sunscreen in the morning. A gentle cleanser and a retinol product at night, alongside nutrient-dense moisturizing oils, balms, or creams to support the skin barrier."

This covers the core principles: antioxidant protection, UV defense, cellular turnover support, and barrier maintenance.

Our LESSE formulations are built on these longevity principles. Rather than overwhelming the skin with aggressive interventions, our essentials support barrier function, provide antioxidant protection, and deliver nutrients for natural repair and regeneration. These formulas work with your skin's natural processes, not against them—tools for long-term skin health rather than quick fixes.

Morning: Protection and nourishment. 

1. Cleanse gently. Remove overnight cellular turnover and prepare skin for active ingredients without stripping the barrier with LESSE Calming Cleanser. 
2. Apply antioxidants. LESSE Ritual Serum provides concentrated antioxidant support while enhancing cellular communication—minimizing oxidative stress and optimizing skin renewal at the cellular level. 
3. Daily SPF. This is non-negotiable. UV protection is the single most impactful topical intervention for skin longevity. LESSE Every Tone SPF 30 provides broad-spectrum mineral protection without compromising barrier health. As Dr. Klemperer emphasizes, "Daily sun protection for the face is an absolute essential ritual." The formula's antioxidant composition and barrier-supporting properties help protect against UV damage while actively nourishing skin. The seamless, dewy finish works across all skin types.

Evening: Repair and regenerate.

1. Cleanse thoroughly. Remove accumulated environmental exposure, sunscreen, and makeup with LESSE Refining Cleanser.
2. Repair. LESSE Regeneration Mist does more than hydrate—it actively supports barrier repair with mineral electrolytes and bioadaptive botanicals. The micro-molecular humectants penetrate efficiently while ingredients like Turkey Tail Mushroom, Astaxanthin, and Gotu Kola calm reactive skin and shield against oxidative stress.
3. Hydrate and correct. LESSE Essential Moisturizer, our multi-corrective Vitamin C complex, delivers stable botanical C along with peptide-rich actives that stimulate collagen synthesis and strengthen the dermal barrier. The formula addresses multiple longevity concerns simultaneously: it inhibits melanin overproduction to reduce hyperpigmentation, provides antioxidant defense, supports the microbiome, and delivers lipid-replenishing compounds that enhance cellular regeneration.

When asked how she navigates the anxiety the beauty industry creates around aging, Dr. Klemperer focuses on gratitude: "For me personally, I try to steep myself in gratitude. I feel so incredibly grateful to be alive. I don't take a single day for granted."

This doesn't mean passive acceptance. "I want to live the rest of my life as fully as possible. I want to feel good in my body -- and in my skin," she explains. "That perspective is a beautiful thing about getting older. I try to focus there with my patients. That still means leaning fully into all of the things that we can control, taking the best care of ourselves possible."

Longevity-focused skin care is about supporting your body's innate capacity for health and vitality throughout your lifespan. These daily practices—applying LESSE longevity-focused essentials, making foundational choices around sleep and nutrition— are expressions of care. They're how you support your body to function at its best.

"We've got this one precious life," Dr. Klemperer says. "How can we feel most alive?" The answer lies in consistent practices that support your skin's capacity for health and regeneration. Not quick fixes or magic products. Just daily rituals that provide your skin with what it needs to thrive—today, tomorrow, and long-term.
