If you’ve been following Love Sweat Fitness, you know that Katie Dunlop is all about sustainable, feel-good wellness. But her recent YouTube update has everyone talking for a different reason: her skin. Over the last five years, Katie has undergone a massive skin transformation, moving toward a more radiant, youthful, and firm complexion.
The best part? It isn’t just about expensive serums. Katie swears by seven specific habits—ranging from budget-friendly nightly rituals to high-tech wellness tools—that have changed the game for her. Here is the breakdown of the habits she uses to look and feel her absolute best.
1. The “Magic” Nightly Oil Blend
Forget the triple-digit eye creams. Katie’s go-to for the delicate skin under her eyes and around her mouth is a simple, cost-effective mix of Castor Oil and Rosehip Oil.
- The Routine: Every night, she smothers her face in a blend of 2/3 Rosehip Oil and 1/3 Castor Oil.
- The Benefit: Beyond deep hydration, castor oil is famous for helping lashes and brows grow. By applying it at night, you capitalize on the body’s natural repair cycle.
2. Shake It Up: The Vibration Plate
It might look a little silly, but Katie spends 10 minutes a day on a Vibration Plate, usually while doing her daily devotions.
- Lymphatic Health: The vibration helps clear the lymphatic system, which is responsible for removing toxins, excess fluid, and waste.
- Cortisol Control: This habit helps lower cortisol—the “stress hormone” that is notorious for destroying collagen in our bodies. The result? Way less puffiness.
3. Light Therapy with iRestore
Katie started using red light therapy years ago to heal scars after a breast augmentation, and she hasn’t stopped since. Her current favorite is the iRestore Illumina Face Mask.
- Red Light: Tells your cells to produce more elastin and collagen (critical, since we lose 1% of our collagen every year after age 25).
- Infrared Light: Works to deeply reduce inflammation.
- Blue Light: Katie uses this specifically during “PMS time” to kill bacteria and prevent hormonal acne breakouts.
4. Creatine: Not Just for Bodybuilders
One of the most surprising additions to her routine is Creatine. While often associated with men in the gym, women naturally have 70-80% less creatine than men, making supplementation vital.
- Anti-Aging: 2025 research has linked lower creatine levels to faster cellular aging.
- Brain Power: Beyond muscle tone, it offers incredible benefits for mental sharpness and cognitive health.
5. The Post-Meal Walk
Walking is Katie’s ultimate “cortisol-lowering tool,” but the timing is what matters most for her skin.
- The Science: Walking after a meal prevents blood sugar spikes. When blood sugar stays elevated, sugar actually binds to collagen and breaks it down—a process that leads directly to wrinkles. By walking, you protect the structural integrity of your skin.
6. Fueling from Within: Protein & Collagen
You can’t have great skin without the right building blocks. Katie focuses on maintaining lean muscle and skin elasticity through her own Love Sweat Fitness supplements.
- Natural Beauty Collagen Peptides: This formula uses Naticol marine collagen, which is clinically proven to reduce fine lines in as little as two weeks. It also includes Vitamin C, Hyaluronic Acid, and Glutathione for brightening.
- LSF Protein Powder: Protein provides the “scaffolding” beneath your skin. Keeping your protein intake high ensures your body has the support it needs to stay firm and “lifted.”
7. Prioritize Deep Sleep
It’s called “beauty sleep” for a reason. Katie emphasizes that Sleep is the foundation that makes all the other habits work.
- HGH Peak: Human Growth Hormone (HGH) peaks during deep sleep. This is what drives cellular turnover and tissue repair.
- The Cortisol Connection: Poor sleep spikes cortisol, which immediately begins breaking down collagen. Katie views her nightly castor oil ritual and her sleep as a team effort—one provides the nutrients, while the other provides the time to heal.
