What is the structure of the skin?
The skin consists of three layers, each with its own function:
A) Epidermis (outer layer of skin)
• Protective layer against bacteria, UV rays, and irritants
• Contains the stratum corneum, which stores moisture
• Melanocytes are located here → responsible for pigmentation
• Renews itself approximately every 28 days
B) Dermis (inner layer of skin)
• Contains collagen and elastin → provide firmness and elasticity
• Blood vessels supply the skin with nutrients
• Hair follicles, sebaceous glands, and sweat glands
C) Subcutis (inner layer of skin)
• Fatty tissue → cushioning and temperature regulation
• Energy storage

Was the skin quality truly determined?
The most important factors:
1. Moisture balance of the skin barrier
2. Sebum production
3. Collagen content
4. Elastin & hyaluronic acid
5. Blood circulation
6. Inflammation level (stress, diet)
7. UV exposure
Almost all skin problems can be traced back to these points.

How to improve your skin quality? (Practical guide)
A) Strengthen the skin barrier (foundation for beautiful skin)
The skin barrier is the most important part – if it is damaged, products are less effective or cause irritation.
Key measures:
• Gentle cleansing (no harsh scrubbing, no aggressive face washes)
• Moisturizing: Hyaluronic acid, glycerin, aloe, panthenol
• Occlusive agents: Ceramide, squalane, shea butter → prevent water loss
Maintain & build collagen
Collagen makes skin firm, plump, and youthful.
Scientifically Proven Measures:
1. Sunscreen (SPF 30–50)
→ UV radiation destroys up to 80% of collagen.
2. Retinoids (Vitamin A, Retinol, Tretinoin)
→ Promote collagen production
→ Improve structure and pore size
→ Reduce wrinkles
3. Vitamin C (Ascorbic Acid)
→ Stimulates collagen
→ Neutralizes free radicals
→ Gives a healthy glow
4. Protein-Rich Diet
→ Collagen consists of glycine, proline, and hydroxyproline
5. Sleep and Stress Management
→ Cortisol destroys collagen
→ Growth hormone builds it up during sleep
⸻
Regulating Pores and Sebum
Large pores are usually genetic, but you can make them appear smoother.
What really helps:
• Niacinamide (4–10%) → reduces sebum production and redness
• Salicylic acid (BHA) → cleanses pores from within
• Retinoids → normalizes sebum production
• Non-comedogenic moisturizer
⸻
Boosts moisture for radiance and glow
Best moisturizing ingredients:
• Hyaluronic acid
• Glycerin
• Panthenol
• Beta-glucan
• Urea (low concentration: 2–5%)
Hydrated skin automatically looks:
• smoother
• plumper
• more radiant
Nutrition & Lifestyle (often underestimated)
Good nutrition = good skin.
Specifically, the following can help:
• Omega-3 (fish, flaxseed oil) → reduced inflammation
• Antioxidants (berries, green tea) → protect against oxidation
• Low sugar intake → reduces acne and inflammation
• Drinking enough water → supports the skin's barrier function
• Exercise → improved blood circulation and cell regeneration
