Natural Acne Solutions
Most acne treatments rely on external solutions like topical creams, antibiotics, or hormonal medications but they rarely address the true internal causes of skin inflammation. Functional medicine flips the script by digging deep into your body’s biochemistry, hormones, nutrition, gut health, and immune responses. It’s a science-based approach that treats the whole person, not just the symptoms. Instead of short-term fixes, this method offers real understanding and lasting skin clarity.

Conditions Addressed with Functional Medicine
Sandra McDonald, NP‘s goal is to strengthen the overall health and wellness of Southwestern Ontario patients with personalized integrative care.Hormonal Imbalance
By regulating estrogen, testosterone, and insulin levels, functional medicine helps stabilize the hormonal swings that fuel acne.
Chronic Inflammation
It addresses inflammation at the source, making a difference not only in acne but also in other inflammatory conditions.
Gut Dysbiosis
An imbalanced gut often leads to acne and skin sensitivity—restoring microbial diversity is key.
Insulin Resistance / Blood Sugar Dysregulation
Blood sugar spikes and crashes can worsen acne. Functional medicine stabilizes glucose with diet and lifestyle strategies.
Frequently Asked Questions
How is functional medicine different from dermatology for acne?
Functional medicine looks inside the body for answers by analyzing gut health, hormones, and immune function rather than just treating skin symptoms.
Will I still need medications or antibiotics?
In many cases, no. Functional medicine often eliminates the need for medications by resolving the root causes that drive acne.
How long until I see results?
Most patients see initial improvements in 4–8 weeks, but full skin healing may take 3–6 months depending on severity and root issues.
Is this treatment just diet-based?
Nutrition is one part, but Sandra McDonald, NP also uses lab testing, advanced supplementation, lifestyle strategies, and sometimes detox protocols.
What kind of tests are done?
We may test for hormones, blood sugar, stool microbiome, food sensitivities, nutrient levels, and inflammation markers.
Will this help if I’ve already tried everything?
Absolutely. Functional medicine is often the breakthrough for people who’ve “tried everything” because it customizes care based on your biology.
