You might think that blackheads, whiteheads, and acne are caused by excessive sebum secretion, but Dr. Eric Berg points out that the real problem is not "too much oil," but "too sticky oil ." Hong Kong people's diet is high in sugar, high in seed oil, and low in nutrition, so skin problems may be a reflection of metabolic imbalance in the body .

🧪5 root causes of thick sebum (not surface problems )
1. Hormonal imbalance ( high DHT )
· Puberty or high stress levels → Increased testosterone levels
· DHT (dihydrotestosterone) makes sebum stickier , which easily clogs pores.
2. High insulin levels (Insulin Resistance )
· High sugar, high starch → insulin spikes → stimulates DHT increase
· Simultaneously inhibits zinc absorption → exacerbates sebum viscosity
3. Zinc deficiency
· Zinc can regulate sebum secretion and texture.
· Zinc deficiency → thickened oil, clogged pores, and uncontrolled DHT
· Zinc is also a cofactor of vitamin A → Zinc deficiency = Vitamin A deficiency
4. Vitamin A deficiency
· Vitamin A helps with skin renewal and oil production.
· Lack → Oily and sticky skin, dead skin buildup, clogged pores
· Zinc is needed to aid absorption → Vitamin A is also ineffective when zinc is deficient .
5. Excessive intake of seed oils
· Including corn oil, soybean oil, sunflower seed oil , etc.
· Highly processed → promotes inflammation and damages liver function
· It hinders bile secretion , thus preventing the absorption of fat-soluble vitamins (such as vitamin A ).
· Seed oils can remain in the body for up to 1.5–2 years , continuously affecting the texture of skin oils.
🍟List of Problem Foods (Skin Killers )
| type | Food examples |
| Refined sugar | Candy, soda, dessert |
| Refined starch | White bread, pasta, biscuits |
| Seed oil | Salad dressing, fried food, processed food |
| Grain-fed animal products | Chicken, eggs, and pork (non-grass-fed) |
✅ Solution: Improve skin from the root cause of diet
1. Sugar-free diet + low-carb diet
· Lowering insulin levels reduces DHT and lipid viscosity .
· Stabilizing hormones and skin metabolism
2. Supplement with zinc and vitamin A
· Zinc sources: red meat, shellfish, sardines, grass-fed beef
· Vitamin A sources: Grass-fed butter, beef liver, cod liver oil (such as cod liver oil ).
· Zinc and Vitamin A work together to improve skin lipids and unclog pores.
3. Avoid seed oils and choose healthy fats.
· Replace with: olive oil, butter, coconut oil, beef tallow
· Choose grass-fed beef, lamb, and wild fish.
· Reduce inflammation and liver burden → Improve vitamin absorption
🧾Conclusion: Skin problems are not just on the surface; they are a reflection of metabolic imbalances within the body.
Hong Kong people lead busy lives, eat out frequently, and consume refined diets. Blackheads, whiteheads, and acne may be warning signs of liver, hormonal, or nutritional imbalances . Starting today, a plate of grass-fed steak, a spoonful of cod liver oil, and a cup of unsweetened green tea will lay a solid foundation for your skin !
