Oily Skin: Mechanisms
Sebum overproduction results from overactivation of the sebaceous glands by DHT (dihydrotestosterone) — produced locally in the skin by 5α-reductase type 1 (different from 5α-reductase type 2 present in the ginger and prostate). Acne, seborrheic dermatitis, and a shiny complexion result from this. Inflammation amplifies sebogenesis: IL-1α and TNF-α directly increase sebum production by sebocytes.
Ginger Mechanisms
1. Inhibition of Cutaneous 5α-Reductase
6-shogaol inhibits 5α-reductase type 1 in cutaneous pilosebaceous follicles, reducing the local conversion of testosterone to DHT. Less cutaneous DHT → less sebocyte stimulation → less sebum.
2. Reduction of Perifollicular Inflammation
NF-κB in sebocytes increases lipogenesis (production of fatty sebum lipids) and IL-8. Ginger inhibits cutaneous NF-κB, reducing the inflammatory component of seborrhea.
3. Anti-bacterial Action (Malassezia, S. aureus)
Seborrheic dermatitis is exacerbated by Malassezia furfur (lipophilic yeast). Ginger has mild anti-fungal activity against Malassezia and anti-bacterial activity against S. aureus (staphylococcus that colonizes seborrheic areas).
INTI Protocol for Oily Skin
| Method | Action | Synergistic |
|---|---|---|
| Oral (hormonal) | 1 INTI bottle/day, morning | Zinc 30 mg (inhibits 5α-reductase), vitamin B6 50 mg |
| Diet | Low GI diet | Reduction of ginger insulin → less cutaneous DHT |
"I had very oily skin since adolescence. 3 months of INTI + zinc, my skin is much less shiny and I have fewer blackheads. Surprised by the effectiveness." — Alexis, 25, Ghent
Ginger & Oily Skin FAQ
Can topical ginger directly reduce sebum?
Topical application (0.5–1% diluted extract) of ginger can locally reduce 5α-reductase and perifollicular inflammation. But systemic action (oral) is more complete because it addresses the overall hormonal context.
Does ginger help with seborrheic dermatitis of the scalp?
Yes — via reduction of hair follicle inflammation and (mild) anti-Malassezia activity. A ginger shampoo (ginger infusion concentrate or extract) can be applied topically. Oral use acts on the systemic inflammatory component.
