Skin Health Starts from Within
Skin is the body's largest organ and reflects your overall health. Creams and serums work from the outside, but truly healthy and radiant skin requires nutrients from within. In Estonia's climate, where a long dark winter and dry indoor air put extra stress on skin, the right internal support is especially important.
Here is a science-backed guide to supplements that support normal skin function.
Essential Supplements for Skin Health
1. Vitamin C — Supporting Collagen Formation
Vitamin C contributes to normal collagen formation for the normal function of skin (EFSA-approved claim). Collagen is skin's structural protein, providing elasticity and firmness.
- Recommended dose: 500-1,000 mg per day
- Form: Buffered vitamin C is gentler on the stomach
- Additional benefit: Protects cells from oxidative stress (EFSA-approved)
- Tip: Split the dose — morning and evening
2. Zinc — Maintaining Normal Skin
Zinc contributes to the maintenance of normal skin (EFSA-approved claim). It is an essential mineral for skin cell renewal and the skin's protective barrier function.
- Recommended dose: 15-25 mg per day
- Form: Zinc bisglycinate (good absorption)
- Tip: Take with food to avoid nausea
- Additional benefit: Contributes to normal macronutrient metabolism
3. Biotin (Vitamin B7) — Skin and Hair Support
Biotin contributes to the maintenance of normal skin and mucous membranes (EFSA-approved claim). It is often known as the beauty vitamin.
- Recommended dose: 2,500-5,000 mcg per day
- Form: D-biotin tablets or capsules
- Additional benefit: Also contributes to the maintenance of normal hair (EFSA-approved)
- Tip: Results typically become visible after 2-3 months of regular use (Patel et al., 2017)
4. Collagen
Collagen is skin's primary structural protein. With age, the body's own collagen production decreases. Hydrolysed collagen peptides are easily absorbed.
- Recommended dose: 5-10 g hydrolysed collagen per day
- Form: Collagen peptides (type I and III for skin)
- Tip: Combine with vitamin C, which contributes to normal collagen formation
- Timeframe: Achieving results typically requires 8-12 weeks of regular use
5. Omega-3 Fatty Acids
Omega-3 fatty acids support the skin's normal moisture balance. EPA and DHA are important for the skin's fatty acid composition.
- Recommended dose: 1,000-2,000 mg EPA+DHA per day
- In Estonian climate: Especially important in winter when dry indoor air dehydrates skin
- Tip: Fish oil contains both EPA and DHA in an optimal ratio
6. Hyaluronic Acid
Hyaluronic acid is a natural substance that binds water and helps maintain skin moisture. The body produces it naturally, but production decreases with age.
- Recommended dose: 100-200 mg per day
- Form: Oral capsules (low molecular weight hyaluronic acid is better absorbed)
- Tip: Drink enough water to support hyaluronic acid function
Lifestyle Factors for Skin Health
Supplements are one piece of the puzzle. Equally important for skin health:
- Hydration: At least 1.5-2 litres of water per day
- Sleep: 7-9 hours — skin cells renew during sleep
- Sun protection: UV radiation is the primary cause of premature skin ageing
- Diet: Antioxidant-rich foods — berries, vegetables, nuts
- Stress: Chronic stress affects skin negatively
Estonia's Climate-Specific Skin Challenges
Estonia's climate presents different challenges to skin across the seasons:
- Winter: Dry indoor air + cold outdoor air = skin moisture barrier stress. Omega-3, hyaluronic acid, and vitamin C are especially important.
- Spring: Allergens and increasing UV radiation. Zinc and vitamin C support skin.
- Summer: UV radiation and sweating. Antioxidant needs (vitamin C, vitamin E) increase.
- Autumn: Transition to drier climate. Begin increasing omega-3 and collagen doses.
Common Mistakes
1. Focusing only on topical products — creams work on the surface; true change comes from within
2. Expecting results too quickly — skin cells renew on a 28-day cycle; give supplements time (at least 2-3 months)
3. Forgetting to drink water — dehydration is skin health's biggest enemy
4. Overdosing biotin — mega doses do not produce better results
5. Ignoring sun protection — no supplement replaces SPF protection
Frequently Asked Questions
Does collagen really help skin?
Hydrolysed collagen peptides are absorbed from the digestive tract. Many users notice changes after 8-12 weeks, but results are individual.
Does biotin help with acne?
Biotin contributes to the maintenance of normal skin, but it is not specifically an acne treatment. For acne, consult a dermatologist.
Can I get all these nutrients from food?
Partially yes — vitamin C from berries, zinc from meat and nuts, omega-3 from fish. However, collagen and hyaluronic acid are harder to obtain in sufficient amounts from food alone.
