Stratia C+C Vitamin C Serum — 15% Total Vitamin C (10% L‑Ascorbic Acid), Lightweight Water‑Free Antioxidant Cream 1 fl oz

Stratia C+C is a water-free, lightweight antioxidant cream delivering 15% total vitamin C (including 10% L-ascorbic acid) plus CoQ10 to brighten and protect skin without heavy residue.

Formulated as a feather-light silicone cream, Stratia C+C combines fast-absorbing L-ascorbic acid with oil-soluble vitamin C (ascorbyl tetraisopalmitate) and coenzyme Q10 in a water-free base. The absence of water improves L-ascorbic acid stability and the formula is designed to evaporate quickly, leaving antioxidants behind rather than a greasy film. It’s intended for daytime antioxidant support, brightening, and helping skin appear more even-toned when used consistently.

How does this formula deliver stable vitamin C?

The C+C serum uses a water-free vehicle to reduce oxidation of L-ascorbic acid and pairs it with oil-soluble ascorbyl tetraisopalmitate for broader skin compatibility. This combination helps maintain potency while minimizing the common instability of pure vitamin C in aqueous products.

• Contains 10% L-ascorbic acid for proven antioxidant activity.
• Includes 15% total vitamin C when counting oil-soluble derivatives.
• Water-free cream base improves ingredient longevity and efficacy.
• Formulated to evaporate, leaving antioxidants without heavy residue.

Will it feel heavy or sticky on my skin?

No — Stratia designed this as a lightweight silicone cream that evaporates within minutes, leaving only the active antioxidants. The texture is typically described as feather-light and non-greasy, making it easy to layer under sunscreen or makeup.

• Silicone-based texture that disappears quickly.
• Leaves behind antioxidant actives, not oiliness.
• Suits morning routines because it layers well with SPF.
• Non-water formula reduces tackiness common in some serums.

How should I use C+C in my skincare routine?

Apply a small amount after cleansing and before sunscreen in the morning, or after treatment serums at night if preferred. Because it’s water-free and concentrated, a little goes a long way; press gently into skin and allow it to absorb fully before applying sunscreen or makeup.

• Use 1–2 pumps or pea-size amount on clean skin.
• Best used in the morning for antioxidant protection.
• Follow with broad-spectrum SPF during daytime use.
• Can be layered with other non-conflicting actives like niacinamide or hyaluronic acid.

Is this suitable for sensitive or reactive skin?

While formulated to be non-irritating, the product contains 10% L-ascorbic acid, which can cause sensitivity in some users. If you have reactive skin, patch testing is recommended and you may prefer to introduce the serum gradually or mix a small amount into your moisturizer at first.

• Contains pure L-ascorbic acid at 10% concentration.
• Non-irritating intent but start slowly if you’re sensitive.
• Patch test on inner wrist or behind ear before full-face use.
• Can dilute with moisturizer for gentler introduction.

Who is this for: Stratia C+C suits anyone looking for a stable, water-free vitamin C formula that balances fast-acting L-ascorbic acid with oil-soluble vitamin C and CoQ10. It’s ideal for users who want a lightweight, non-greasy antioxidant step in their morning routine and those who prefer concentrated, scientifically minded formulations. If you’re new to vitamin C or have very reactive skin, consider a gradual introduction or consult skincare guidance to determine the right frequency and pairing with other actives.
