Lactobacillus / Bifidobacterium / Gut-Skin Axis
The gut-skin axis is a well-established relationship: gut dysbiosis is associated with acne, rosacea, eczema and psoriasis. Oral probiotics — particularly Lactobacillus rhamnosus, L. paracasei and L. acidophilus — have shown efficacy in RCTs for reducing acne severity, eczema symptoms and rosacea flushing.
Oral 10–50 billion CFU/day from high-quality multi-strain probiotic with food. Look for refrigerated products with guaranteed potency.
