20% vitamin C + vitamin E — clinically tested for dark spots, fine lines, skin tone and collagen support
The Gold Serum contains the same 20% vitamin C and vitamin E brightening complex as the YOUTH Vitamin C Serum — clinically tested to reduce fine lines, dark spots and age spots, smooth skin texture, improve skin tone, support collagen production and reinforce the moisture barrier.
Raspberry cell extract — plant stem cell technology for epidermal renewal and protection
Raspberry cell extract contributes plant stem cell actives that support epidermal cell renewal and protect the skin against environmental and UV oxidative stress — a third mechanism alongside the vitamin C and E antioxidant complex.

Vitamin C at 20%: why concentration is everything in brightening serums
Topical vitamin C studies show a clear dose-response relationship up to approximately 20% concentration: below 10%, the brightening and collagen effects are minimal; at 10–15%, moderate; at 20%, maximum efficacy within safe skin tolerability limits. The YOUTH Gold Serum formulates at this optimal 20% level.
The vitamin C and vitamin E combination provides two complementary mechanisms: vitamin C directly inhibits melanin synthesis and stimulates collagen; vitamin E regenerates spent vitamin C molecules, extending their activity. Together they provide significantly stronger and longer-lasting antioxidant protection than either alone. This synergy is well-documented in dermatological literature and is the reason the best brightening serums contain both actives.
Raspberry cell extract completes the formula with plant stem cell technology. Where vitamin C and E work primarily on melanin synthesis and oxidative damage, raspberry cell extract supports epidermal cell renewal — accelerating the turnover of pigmented surface cells and revealing the fresher, more evenly pigmented cells beneath. The three actives address pigmentation through three distinct pathways simultaneously.

How to use
AM use after toner — vitamin C for daytime protection
Apply in your AM routine after the YOUTH Toner (33510). Vitamin C provides antioxidant protection against daytime UV and pollution. Press 2–3 pumps into the face and neck and allow 60 seconds to absorb before moisturiser.
Follow with Day Cream and SPF for the complete AM stack
Apply YOUTH Moisture Lock Day Cream (33508) to seal the serum actives, then the Age Defense Mineral Moisturiser SPF 15 (33516) for UV protection. Vitamin C + SPF is the gold-standard daytime anti-pigmentation and anti-ageing stack.
Daily AM use — antioxidant protection is cumulative
Use every morning for continuous vitamin C defence. Keep the bottle tightly closed and away from direct sunlight to preserve vitamin C potency through the life of the bottle.
