Won’t that yellow vitamin C serum stain my skin?

If you’ve ever received my Vitamin C serum (or hand cream) and thought “Wow — that’s yellow!” you’re absolutely right.

That rich golden hue isn’t added colour, or mica. It comes directly from one of the most nutrient-dense botanical oils used in skincare: sea buckthorn berry oil.

And that colour tells an important story.

Colour in Natural Skincare = Active Nutrition

In truly natural skincare, colour often comes from the plant itself — and the deeper the colour, the more biologically active compounds it usually contains.

Sea buckthorn berry oil is naturally bright yellow to deep orange because it’s exceptionally rich in:

• Carotenoids

• Fat-soluble vitamins

• Antioxidants

• Essential fatty acids

This isn’t just a “nice-to-have” ingredient — it’s a powerhouse, a functional, high-performance component of the formula.

What Is Sea Buckthorn Berry Oil?

Sea buckthorn (Hippophae rhamnoides) is a hardy plant that thrives in extreme conditions — strong winds, cold climates, intense sun.

To survive, it produces a remarkably protective oil inside its berries. Unlike sea buckthorn seed oil, which is pale, berry oil is extracted from the whole fruit — and that’s where the magic (and the colour) comes from.

Exceptionally Rich in Carotenoids

Carotenoids are powerful antioxidants responsible for the oil’s yellow-orange colour.

On the skin, they:

• Help neutralise damaging free radicals

• Support repair after environmental stress (sun, wind, cold, pollution)

• Improve overall skin resilience and vitality

In a vitamin C serum, this adds another layer of antioxidant defence, helping to protect the skin from daily oxidative stress — one of the primary drivers of premature ageing.

Naturally High in Vitamin E

Sea buckthorn contains multiple forms of tocopherols and tocotrienols (vitamin E). In a vitamin C serum, this is particularly important, as vitamin E works synergistically with vitamin C to enhance antioxidant performance and stability.

Vitamin E:

• Strengthens the skin barrier

• Reduces moisture loss

• Supports healing and comfort in dry, cracked skin

Together, vitamins C and E create a more complete antioxidant network, supporting brighter, more resilient skin

Rare Omega Fatty Acid Profile (Including Omega-7)

Sea buckthorn berry oil is one of the very few plant oils naturally rich in palmitoleic acid (omega-7) — a fatty acid also found in healthy human skin.

Omega-7:

• Supports skin regeneration

• Improves elasticity

• Helps soothe compromised or irritated skin

Combined with omega-3, 6, and 9, this creates a lipid profile that closely mimics the skin’s natural barrier — helping your serum not just treat the skin, but support its structure.

Supports Ageing and Thinning Skin

As we age, skin becomes thinner, drier, and slower to repair — especially on the hands (which is why my hand cream also features sea buckthorn oil).

Sea buckthorn helps by:

• Supporting cell turnover

• Improving skin softness and flexibility

• Giving skin a healthier, more resilient appearance

Sea buckthorn complements vitamin C’s role in collagen support and brightening

Will the Yellow Colour Stain My Skin?

A very common (and sensible!) question

The answer: No — not when properly formulated.

Although sea buckthorn berry oil is intensely coloured, it’s used at carefully balanced levels within the serum. It absorbs readily into the skin rather than sitting on the surface, so you won’t be left with any yellow tint.

Why I Choose Ingredients That Look Like This

I use ingredients that do something.

That yellow colour is a sign your skin is receiving a concentrated dose of protective, restorative nutrients.

And in a vitamin C serum designed to support brightness, resilience, and long-term skin health — that’s exactly what you want.
