We formulated Shine Vitamin C Serum™ with MAP (magnesium ascorbyl phosphate), a stable form of vitamin C that brightens and evens tone without the irritation of traditional ascorbic acid. 

Built on a base of three house-distilled hydrosols (geranium, chamomile, witch hazel) rather than plain water, this serum delivers botanical benefits from the first ingredient. Goldenseal extract, green tea, and helichrysum provide antioxidant protection against UV exposure and environmental stress, while phytic acid supports gentle brightening. Hyaluronic acid delivers multi-depth hydration that lasts. 

Key Effects: Brighten • Even Tone • Hydrate • Protect

Key Botanical + Clinical Ingredients: Vitamin C, Goldenseal Extract, Green Tea Extract, Helichrysum Extract, Geranium + Chamomile + Witch Hazel Hydrosols, Phytic Acid, Hyaluronic Acid

Best For: Dullness, uneven tone, dark spots, dehydration, sensitive skin that can't tolerate ascorbic acid, anyone seeking stable daily vitamin C

This is a daily brightening serum designed to prevent cellular stress from UV exposure and protect from damage that can create fine lines without the stinging, oxidation, or sensitivity that can come with traditional vitamin C.

Pair with: Glow Oil (daytime protection layer), Fresh Start Cleanser (morning prep)

Benefits

Shine is for people who want daily vitamin C performance without the drama. It's especially good for: Sensitive skin that reacts to ascorbic acid, dullness or uneven tone, post-inflammatory hyperpigmentation (dark spots after breakouts), dehydrated skin that needs brightness + moisture, and anyone who wants a stable, low-maintenance vitamin C serum.

If you want to brighten your skin without stinging, peeling, or oxidation anxiety, this is it.
