buttah. by Dorion Renaud 15% Vitamin C Serum 1 fl oz — Brightening, Ferulic Acid & Vitamin E

buttah. by Dorion Renaud 15% Vitamin C Serum is a lightweight, antioxidant-rich facial serum formulated to help even skin tone, reduce the look of dark spots, and support smoother-looking skin.

This serum blends a stable 15% vitamin C concentration with ferulic acid and vitamin E to enhance antioxidant protection and improve product performance. Designed for daily use in a morning or evening routine, it has a creamy, non-greasy texture and a subtle green tea scent that calms the senses. The formula focuses on brightening and comfort rather than clinical treatment claims, making it suitable as part of a targeted skincare regimen to address uneven tone and post-inflammatory discoloration.

How should I use this vitamin C serum in my routine?

Apply the serum after cleansing and toning but before heavier creams and oils. Start with 1–2 drops, gently patting it into dry or slightly damp skin; follow with moisturizer and sunscreen in daytime routines. Use consistently for visible texture and tone improvement over weeks.

• Use morning and/or evening depending on tolerance
• Apply 1–2 drops to face and neck, avoiding eyes
• Layer under moisturizer; apply broad-spectrum SPF after daytime use
• Patch-test if you have very sensitive skin

What active ingredients are in the formula and why do they matter?

The serum combines 15% vitamin C with ferulic acid and vitamin E to create a synergistic antioxidant system that supports brightening and protects against environmental stressors. Green tea extract contributes soothing properties and a light fragrance, while anti-inflammatory elements aim to reduce redness and irritation.

• 15% vitamin C for brightening and evening skin tone
• Ferulic acid to stabilize and enhance antioxidant effects
• Vitamin E to nourish and support skin barrier function
• Green tea extract provides calming and antioxidant support

Will this serum work for sensitive or dry skin?

The formulation includes soothing and nourishing agents intended to make the serum tolerable for many dry or reactive skin types, but individual sensitivity varies. Because it contains active acids and potent antioxidants, start slowly—use every other day or mix with moisturizer—and monitor for irritation.

• Gentle green tea scent and anti-inflammatory components
• Vitamin E and comforting base to help reduce dryness
• Begin with lower frequency to assess tolerance
• Discontinue if persistent redness or stinging occurs

How quickly can I expect to see results and how should I store it?

Visible improvements in brightness and the appearance of dark spots typically appear with consistent use over several weeks to months. Store the serum in a cool, dark place, and keep the bottle tightly closed to preserve potency—refrigeration can extend freshness but is not required.

• Noticeable tone improvement often in 4–12 weeks with regular use
• Keep bottle capped and away from direct sunlight and heat
• Use within the manufacturer’s recommended period after opening
• Refrigeration optional to prolong active ingredient stability

Who is this for: buttah. 15% Vitamin C Serum is for anyone looking to even skin tone and reduce the visible appearance of dark spots while using a formulation that balances potency with soothing support. It suits dry, combination, and normal skin types seeking an antioxidant-rich step in their skincare routine; those with very sensitive or compromised skin should patch-test and introduce the serum gradually. Pair with daily sun protection for best maintenance of results.
