5 Low-Tox Swaps That Transformed My Skin & Energy at 40

Hey friends, welcome back to SBK Living!

Turning 40 this year has been one of the most empowering seasons yet. I genuinely feel clearer, stronger, and more energized than I did in my 20s — chasing my boys around our home, showing up for my business, and actually enjoying the process. It’s not about doing everything perfectly. It’s about intentional swaps that compound over time and support how I want to feel in this chapter.

These changes have helped me support my skin barrier, hormone balance, sleep quality, and gut health — all of which feel so interconnected in my 40s. A few of these swaps are ones I’ve shared pieces of before (and they’re all detailed with my exact product recommendations in the Low-Toxic Living Guide), but today I’m pulling together the five low-tox swaps that have made the biggest visible and felt difference in my skin clarity and steady, all-day energy.

Let’s dive in.

1. Gentle Double Cleanse: Oil Cleanser + Non-Toxic Micellar Water

Why I swapped: For years I used foaming cleansers that left my skin feeling “squeaky clean.” As I moved into my late 30s and now 40s, that stripping feeling started showing up as redness, dryness, and a compromised barrier — especially after long days outside with the boys or post-laser recovery. I wanted something that actually respected my skin instead of fighting it.

What I love: An oil cleanser first melts away sunscreen, sweat, and any makeup, then I follow with a gentle, non-toxic micellar water. My skin feels calm, balanced, and hydrated instead of tight. The redness I used to battle has calmed dramatically, and my barrier looks stronger and more even. This simple ritual (which I’ve been refining for over 15 years) is now non-negotiable for my 40+ skin.

I’m currently loving the Dime Beauty Nourishing Cleansing Oil and the Uncommon James Micellar Water.

Quick tip: Look for oil cleansers with jojoba, squalane, or calendula. Pair it with a micellar that’s free of harsh surfactants. Your skin will thank you.

2. Daily Mineral SPF — Every Single Morning (Yes, Even Indoors)

Why I swapped: I used to reach for chemical sunscreens without thinking twice. Once I learned more about how those filters can interact with hormones and sensitive skin, I made the switch to mineral options. At 40, protecting my skin barrier and preventing further damage felt even more important.

What I love: Mineral SPF (zinc-based) sits on top of my skin like a gentle shield instead of soaking in. My face looks calmer, less reactive, and I don’t get that flushed redness I used to see after being outside. I layer the Solara mineral SPF first, then follow with the Saie tinted moisturizer. It layers beautifully and gives me light coverage, typically wearing this instead of foundation. I reapply when we’re out playing, boating or hiking, and it’s become part of my “feel good” morning ritual.

3. Prioritizing Clean, Protein-Focused Eating (100–130g/Day — No Intermittent Fasting)

Why I swapped: I used to undereat protein and experiment with intermittent fasting, thinking it would help with energy and skin. In my 30s, I realized it was doing the opposite — especially for my hormones. As women, we often don’t do well with long fasting windows because it can stress the body and mess with cortisol and other hormones. Shifting to consistent, clean protein throughout the day has been transformative for stable energy, hormone support, and gut health.

What I love: I aim for 100 to 130 grams of protein daily with nourishing, gluten-free meals that fuel my life. My go-tos include a simple grass fed ground beef and boiled egg bowl (pictured below), an iced collagen latte (2 scoops Carnivore Aurelius Pure Collagen Peptides), protein fiber oatmeal bowl (One Degree oats + Paleo Valley Bone Broth Protein + collagen, berries, flax, and cinnamon), and strawberry collagen protein smoothie (frozen strawberries, collagen, bone broth protein, flax for hormone support, and coconut milk). These keep my blood sugar steady, reduce afternoon crashes, support my gut, and give my skin that healthy, resilient glow from within. No more restrictive windows — just consistent nourishment that helps me feel strong and energized.

Quick tip: Start by adding a scoop of collagen or bone broth protein to your morning drink or breakfast. It’s an easy win that compounds for skin elasticity, all-day stamina, and gut health. My favorites are Carnivore Aurelius Pure Collagen Peptides and Paleo Valley Bone Broth Protein.

4. Swapped Synthetic Bedding & Activewear for Organic Cotton & Linen

Why I swapped: I became more aware of microplastics shedding from polyester and nylon — both on my skin while I sleep and during workouts, and in the environment. Synthetics also trap heat and sweat, which wasn’t helping my skin, hormones, or gut.

What I love: Organic cotton and linen feel breathable and get softer with every wash. My skin is less irritated overnight, I sleep cooler and deeper, and I feel good knowing I’m not exposing myself (or my family) to unnecessary microplastics. Here is a blog post detailing my favorite non-toxic bedding options. For activewear, I shared all my favorite brands in my recent post, Non-Toxic Activewear: Why I Made the Swap and the Brands I’m Loving Right Now — check that out if you’re looking for specific recommendations!

Better sleep + less irritation = better skin repair, hormone balance, and gut health. It all connects.

5. Circadian Rhythm Support: Morning Sunlight + Evening Blue-Light Management

Why I swapped: I used to scroll in bed with all the lights on and wonder why my sleep (and therefore my skin and energy) suffered. Blue light at night disrupts melatonin, and poor sleep shows up fast on your face, in your mood, and in your gut health — especially in perimenopause and beyond.

What I love: This has been one of the highest-ROI swaps for both skin and energy. Every morning I step outside for 10–20 minutes of natural light (no sunglasses or sunscreen at first) while I drink my collagen latte. During the day I use full spectrum light bulbs (ditched the LEDs), in the evenings I switch to warm red bulbs, wear blue-light blocking glasses (clear during the day, amber at night), and keep screens dim. My sleep is deeper, my mornings feel brighter, my gut feels more balanced, and my skin repairs itself overnight like it should. I have steady energy all day — no more afternoon crashes — and I feel more in sync with my body.

It’s simple, free, and one of the most powerful things I do for my 40+ wellness.

These five swaps didn’t happen overnight, but layered together they’ve completely shifted how my skin looks and how I feel in my body. Clearer, calmer skin. More stable energy. A deeper sense of taking care of myself so I can show up fully for my family and the work I love.

Remember: progress over perfection. You don’t have to do all five at once. Pick the one that feels most doable this week and build from there.

Here’s to feeling good in our skin and in our homes at every age. You’ve got this.
