Beautiful skin starts from within — literally. Topical creams work on the surface; supplements provide the building blocks from which the body itself can make collagen, elastin, and hyaluronic acid. At Plenthera, you'll find the complete beauty stack: collagen peptides, vitamin C (cofactor in collagen synthesis — EFSA-recognized), zinc, hyaluronic acid, astaxanthin, and biotin. Allow 8-12 weeks of consistent use for visible effects.
Which skin stack is right for you?
| Situation | Stack | Timing |
|---|---|---|
| General skin approach | Collagen + C + zinc | Daily |
| Anti-aging premium | Collagen + C + astaxanthin + hyaluronic acid | Daily 12+ weeks |
| Dry skin | Omega 3 + collagen + biotin | Daily |
| Acne / problematic skin | Zinc + omega 3 + vitamin A (if no retinol) | Consult a doctor |
| Pigmentation | Vitamin C + astaxanthin (UV protection support) | Morning |
What is beautiful skin from within?
The skin is built from three main components: collagen (structure, 80% of dermis), elastin (elasticity), and hyaluronic acid (hydration). From the age of 25, collagen production decreases by approximately 1% per year — gradually leading to drier and looser skin. Beauty supplements provide building blocks and cofactors from which the body can build these structures.
The scientific basis for "drinking collagen to get beautiful skin" is nuanced. The body breaks down collagen peptides into amino acids — which can be used anywhere, not specifically for the skin. Nevertheless, clinical studies (especially with 5-10 g/day collagen peptides for 8-12 weeks) consistently show improvements in skin hydration, elasticity, and wrinkle depth. The effect seems to work by stimulating the body's own collagen production through the amino acids glycine and proline.
Vitamin C is the only EFSA-recognized component for collagen formation for the skin. It is an indispensable cofactor in the hydroxylation of proline and lysine — without sufficient vitamin C, the body cannot make functional collagen. For those supplementing with collagen, a vitamin C supplement of 500 mg/day is a logical step.
For a complete beauty theme, add: zinc (EFSA claim for skin), biotin (EFSA claim for skin and hair), astaxanthin (UV protection and antioxidant) and omega 3 DHA (skin fatty acids). Plus always: sun protection, sleep, hydration, and sugar restriction.
Beautiful Skin from Within and EFSA — what is scientifically recognized?
EFSA has not recognized an overarching skin claim. However, there are components with relevant recognized claims:
"Vitamin C contributes to normal collagen formation for the normal function of the skin."
"Zinc contributes to the maintenance of normal skin."
"Biotin contributes to the maintenance of normal skin."
"Vitamin A contributes to the maintenance of normal skin."
Threshold values apply to daily intake that provides at least 15% RI.

How to use beautiful skin from within?
Simple basic approach for skin:
- Start with the basics: collagen 5-10 g + vitamin C 500 mg + zinc 10 mg.
- Give the stack at least 8-12 weeks — skin effects are cumulative.
- Add astaxanthin for antioxidant protection (skin + eyes).
- For dry skin: add omega 3 DHA.
- Always combine with SPF, hydration, and sleep.
- Limit sugar — advanced glycation end products (AGEs) harm collagen.
- For specific skin issues (acne, eczema, rosacea): dermatological care, not just supplements.
Myths and misconceptions about beautiful skin from within
Myth 1: "A pill solves skin issues."
Supplements are an addition to lifestyle, not a replacement.
Myth 2: "The more supplements, the better."
Stacking doesn't work — choose a targeted stack and allow time.
Myth 3: "Supplements work acutely for skin."
Cumulative effect, allow 4-8 weeks.
Myth 4: "All brands are equal."
Quality varies greatly — choose premium for targeted effect.
