Botox or botulinum toxin type A (BoNT-A) has significant and beautifying effects on several askpects of skin quality. Both the injection technique,, timescale of effect, and the physiological mechanism is significantly different from the classic neuromuscular paralysis that reduces dynamic wrinkles. Skin quality including the pore size, oily sebum production, redness and flushing, texture, fine lines all improve with Botox for skin health. These qualities will take effect more slowly, but then actually have a longer duration of action than the rapid transient muscle-relaxing effect, indicating the underlying pathways are distinct.
Mechanism of action is complex!
Botox’s skin-improving effects may go beyond simply relaxing muscles. Research suggests it interacts directly with skin cells involved in collagen support, oil production, and circulation. The chemical messenger modulating this effect is acetylcholine-driven signaling pathways that help regulate tissue remodeling and skin behavior, Botox injected into the skin may improve skin elasticity, refine texture, and soften fine lines. These benefits appear to occur through pathways within the skin itself, rather than solely through its effects on facial muscles. This may help explain why many patients notice smoother, firmer, and more radiant skin following treatment.
New Collagen
Botox BoNT-A stimulates collagen production and reorganizes the dermal collagen network. The collagen molecules relax, repair, align correctly to restore the skin extracellular matrix (area around skin cells) and producing more youthful skin characteristics. Skin cells called fibroblasts that product collagen have dermal fibroblasts showed BoNT-A increased procollagen type I peptide, upregulated type I collagen expression, and downregulated matrix metalloproteinases (MMPs) that breakdown collage. Over time this dual effect (more synthesis, less breakdown) remodels aging or damaged skin. Because collagen synthesis and elastic remodeling take time, these changes account for the delayed but prolonged improvement
Reduces Oily Sebum and pore-size effect
BoNT-A decreases sebum production and pore size. Specifically this is from the inhibition of acetylcholine-driven sebocyte lipid production; partial denervation of the arrector pili muscle around hairs (a cholinergically controlled smooth muscle whose contraction normally compresses sebaceous acini and expels sebum); and a reduction in the number of sebocytes and hair follicles. The pore-shrinking effect is measurable as early as one week but persists over 6 months, consistent with the slow recovery of these structures. The pores shrink producing the glass effect.
Less Flushing, Less Inflammation of Skin after Botox
BoNT-A, Botox, reduces facial erythema and flushing, likely via effects on vascular endothelial cells and cholinergic mediators controlling cutaneous vasodilation, supporting its off-label use in rosacea and flushing. Botox BoNT-A demonstrates anti-inflammatory properties (relevant to acne, rosacea, and inflammatory dermatoses), which may contribute to overall skin-quality improvement through modulation of signaling in immune and epithelial cells.
Our Technique is Unique
Overall, the currently favored model is that intradermal/microdroplet (“microtoxin”) delivery targets these non-neuronal pathways—fibroblast-driven collagen homeostasis, sebocyte and arrector pili activity, and vascular/inflammatory mediators—whereas conventional intramuscular injection primarily reduces dynamic rhytides via neuromuscular blockade. So for muscles: inject the muscles, for skin: inject the Botox into the skin with little droplets. Dosage varies for what we want to accomplish for your skin, but does take many very small injections. Studies have been completed with both Xeomin and Botox.
When combined with Skinvive, Exosomes, and hyaluronic acid building skin care the effect is even better.
