The Bright Side: What’s Really in Solstice Serum - Althaea Soul

Vitamin C: hyped by many, misunderstood by most. Used wrong, it oxidises, irritates, or just... doesn’t do much. But when it’s done right? It’s skin-transforming.

Vitamin C serums often get tossed into the “brightening” category and left at that. But when done right, they’re not just a glow gimmick — they’re barrier-boosting, collagen-coaxing, pigment-fighting powerhouses.

Meet Solstice — your morning sunshine in serum form. Packed with 10% L-ascorbic acid (the gold standard of vitamin C) and stabilised for peak performance, this little bottle is here to transform dull, stressed, or sun-kissed skin into a luminous masterpiece. And yes, it smells faintly like citrusy joy, because science and sensorial pleasure can coexist.

🔬 The Skin-Boosting Breakdown

Every ingredient in Solstice has a job to do — and trust us, there are no slackers in this serum.

🍊 Ascorbic Acid (10% Vitamin C)

Let’s start with the star. L-ascorbic acid is the most potent, active form of vitamin C — but also notoriously unstable. That’s why many serums oxidise faster than avo on toast.
But not this one. Solstice uses smart formulation to keep things stable and effective.

What it does:

  • Neutralises free radicals (sun, pollution, stress — the whole chaotic crew)

  • Boosts collagen production for firmer, bouncier skin

  • Fades dark spots and uneven tone

  • Brightens like your skin’s had eight hours of sleep and a green juice

💧 Glycerin & Propylene Glycol

These are your moisture magnets — humectants that draw water into the skin and help keep it there.

Bonus: They also help vitamin C penetrate deeper, meaning better results and faster glow.

🧴 Isododecane

This lightweight emollient creates a smooth, silky finish without clogging pores or feeling greasy.
Think of it as the primer for your skincare — locking in actives while giving that breathable second-skin feel.

🌬️ Cyclopentasiloxane & Dimethicone

Yep, these are silicones — and no, they’re not the villains they’ve been made out to be. These silky agents:

  • Provide that weightless, non-tacky glide

  • Help reduce water loss

  • Act as skin conditioners, keeping things smooth and comfy
    They’re breathable, non-comedogenic, and actually help sensitive skin tolerate strong actives like vitamin C.

🧪 Tocopherol Acetate (Vitamin E)

Vitamin C’s ride-or-die. This antioxidant:

  • Enhances the power and stability of vitamin C

  • Helps calm inflammation

  • Strengthens the skin barrier
    The result? Brighter skin that’s less reactive and more resilient.

🍊 Citrus Sinensis (Sweet Orange Oil)

Here for the vibe and the benefits.
This essential oil gives Solstice its subtle citrus scent — no synthetic fragrance needed — and offers a gentle dose of antioxidant and antimicrobial action.

✨ Polysilicone-11

A silicone-based texture enhancer that also works like a skin blurring filter IRL.
It creates a breathable barrier, smooths over fine lines and uneven texture, and helps the formula stay lightweight and stable.

  • Pro tip: Store it in a cool, dry place to preserve the potency (no steamy bathroom shelves, please).

✔️ Especially beneficial for pigmentation, sun damage, or general dullness
