Sanitas Vita C Serum 30% THD Vitamin C, 1 oz — Antioxidant Brightening Oil-Serum with Vegan Squalane

Sanitas Vita C Serum is a 30% THD vitamin C antioxidant serum blended with vegan squalane and exotic seed butters to brighten skin, hydrate deeply, and improve texture.

This nutrient-rich, fully active serum pairs a high concentration of lipid-soluble THD vitamin C with moisturizing botanicals to help the skin appear smoother and more even-toned. Formulated without parabens, phthalates, dyes, harsh preservatives, or gluten, the product is cruelty-free and made in Sanitas’s Boulder, Colorado facility. The lightweight oil-serum texture is built to deliver antioxidant protection while replenishing natural lipids for a firmer-looking finish.

How does this serum help brighten and even skin tone?

The 30% THD vitamin C in this formula is a lipid-soluble derivative designed to penetrate and help support skin clarity and radiance. Regular topical use can help address the look of dark spots and uneven pigmentation while fortifying the skin’s response to environmental stressors.

• 30% THD vitamin C: high-strength antioxidant in a lipid-soluble form
• Targets visible dark spots and dullness for a brighter appearance
• Supports a more even-looking complexion with consistent use

Will this serum hydrate without leaving a greasy feel?

Sanitas Vita C Serum balances rich emollients with a lightweight carrier to sink in and leave skin feeling nourished rather than oily. Plant-derived butters and vegan squalane restore moisture and strengthen skin’s natural lipid barrier for soft, supple texture.

• Murumuru and cupuaçu seed butters: deep but non-greasy hydration
• Vegan squalane: skin-identical lipid that improves ingredient delivery
• Fast-absorbing oil-serum base suitable under moisturizers or SPF

Is this serum suitable for sensitive or reactive skin?

The formula omits common irritants such as parabens, phthalates, dyes, harsh preservatives, and gluten, and uses plant butters to help calm redness. As with any high-concentration active, start gradually and patch test to assess tolerance before full-face application.

• Free from harsh preservatives and known common irritants
• Soothing seed butters help reduce the look of irritation
• Recommended: patch test and introduce slowly into your routine

How should I incorporate this serum into my daily routine?

Use the serum after cleansing and toning, applying a few drops to face and neck and following with a moisturizer and SPF in daytime. At night, layer it under your usual moisturizer; because it contains a potent vitamin C concentration, adjust frequency based on your skin’s response.

• Apply 1–3 drops to clean skin, morning or night
• Follow with moisturizer; always use SPF during daytime
• Introduce slowly (every other day) if you have sensitive skin

Who is this for: Sanitas Vita C Serum is aimed at people seeking a potent antioxidant serum to improve the look of uneven texture, dullness, and dark spots while also replenishing moisture. It suits those who prefer clean, cruelty-free skincare made in the U.S., and users comfortable introducing a high-strength vitamin C derivative into their regimen. If you want brighter-looking skin with added lipid nourishment and prefer an oil-serum finish, this product fits that need.
