Ingredient breakdown

INGREDIENTS

L-Ascorbic Acid (Vitamin C) 15%Gold Standard

The purest and most researched form of vitamin C. At 15%, it provides powerful antioxidant protection while remaining tolerable for most skin types.

  • Clinical Research: Studies show 15-20% L-ascorbic acid stimulates collagen synthesis and reduces hyperpigmentation
  • Mechanism: Neutralizes free radicals, inhibits melanin production, and supports collagen formation
  • Stability: Mix-to-activate system maintains potency by keeping powder separate until first use
Has a "reservoir effect" - stays active on skin for up to 72 hours and cannot be washed off.

Ferulic Acid 0.5%Proven

A plant-derived antioxidant that enhances the stability and effectiveness of vitamins C and E when combined.

  • Synergy: Duke University research shows vitamin C + E + ferulic acid provides 8x more photoprotection than vitamin C alone
  • Source: Derived from plant cell walls, particularly rice bran and oats
  • Function: Stabilizes vitamin C, extends shelf life, and provides additional UV protection

Tocopherol (Vitamin E) 1%Proven

A lipid-soluble antioxidant that works synergistically with vitamin C to neutralize free radicals and protect cell membranes.

  • Benefit: Maintains moisture levels and soothes irritation
  • Synergy: Regenerates vitamin C after it neutralizes free radicals, extending antioxidant protection

Pumpkin Ferment Extract -Promising

Provides gentle enzymatic exfoliation to dissolve dead surface skin cells and boost the penetration of active ingredients.

  • Function: Natural fruit enzymes break down keratin bonds for gentle exfoliation
  • Benefit: Enhances absorption of vitamin C complex for better results
Fermented ingredient may not be suitable for those prone to fungal acne (Malassezia folliculitis).

Marula Seed Oil -Hydrating

Lightweight, fast-absorbing oil rich in antioxidants and essential fatty acids. Known as "the elephant's favorite treat" in South Africa.

  • Composition: High in oleic acid, linoleic acid, and vitamin E
  • Source: Extracted from the fruit of the Sclerocarya birrea tree

Frequently asked questions

FAQ

Yes! Drunk Elephant confirms that C-Firma Fresh is safe for pregnant and nursing women. It contains no retinoids, salicylic acid, hydroquinone, or chemical sunscreens - all ingredients typically avoided during pregnancy. Vitamin C is considered safe and beneficial during pregnancy for its antioxidant properties.

No, C-Firma Fresh is NOT fungal acne safe. It contains Lactobacillus/Pumpkin Ferment Extract, Lactobacillus/Punica Granatum Fruit Ferment Extract, and Sclerocarya Birrea Seed Oil (Marula Oil) - all of which contain fatty acids or ferments that can feed Malassezia yeast. If you're prone to fungal acne, consider alternatives like Paula's Choice C15 Super Booster or SkinCeuticals C E Ferulic.

Yes, but with caution. Use vitamin C in the morning and retinol/acids at night to avoid irritation. If layering with acids, apply vitamin C first, wait a few minutes, then apply acids. Drunk Elephant recommends their "smoothie" method of mixing compatible products. Start slowly and build tolerance before combining multiple actives.

C-Firma works best for normal, oily, and combination skin types looking to address dullness, uneven tone, dark spots, and early signs of aging. It's also suitable for dry skin when layered with hydrating products. Those with very sensitive skin should start slowly as 15% vitamin C can be potent. Not recommended for fungal acne-prone skin.

Most users notice an immediate glow and improved radiance within the first 1-2 weeks. Visible brightening and dark spot fading typically begins around weeks 4-6. Significant improvements in hyperpigmentation, firmness, and overall skin texture usually appear after 8-12 weeks of consistent daily use.

Apply C-Firma in the morning after cleansing and toning, but before moisturizer and sunscreen. Apply to clean, dry skin - water dilutes vitamin C effectiveness. Wait 1-2 minutes before layering other products. Can be mixed with Drunk Elephant B-Hydra serum for added hydration. Always follow with SPF 30+ sunscreen.

C-Firma has a low comedogenic rating of 1/5, meaning it's unlikely to clog pores for most people. The lightweight serum formula is designed to absorb without leaving heavy residue. However, individual reactions vary - if you're very acne-prone, patch test first. The formula is silicone-free which some find less pore-clogging than silicone-based serums.

Once mixed, C-Firma stays fresh for approximately 6 months. The innovative mix-to-activate system ensures you're getting fresh vitamin C from the first use. Store in a cool, dry place away from direct sunlight. If the serum turns dark orange or brown, it has oxidized and should be replaced. Use daily for best results - one bottle typically lasts 2-3 months with regular use.

— Skincarisma verdict
4.3 / 5 ★★★★☆

Verdict: Drunk Elephant C-Firma Fresh Day Serum is a premium vitamin C serum that delivers on its promises of brightening, firming, and protecting skin from environmental damage. The innovative mix-to-activate system ensures maximum potency, and the clean formula is suitable for pregnancy and most skin types. While the price point is high and texture slightly tacky, the proven CEF complex and visible results make it a worthy investment for those serious about anti-aging. Best suited for normal to oily skin; those with fungal acne or sensitive skin should consider alternatives.

question
lightbulb What are Notable Effects & Ingredients?

Ever used a product that promised a certain effect but provided no results? It might not have contained any notable ingredients that could have been responsible for that promised effect. It doesn't matter what the marketing or packaging «promises» it can do, if it doesn't contain anything that can help - then the likelihood of it helping is low.

We help you identify key notable ingredients that have been shown to help with effects such as acne-fighting, brightening, UV-protection, wound healing & anti-aging to help you achieve your skincare goals smarter. Please note that different notable ingredients have varying levels of research behind them, some are extremely well proven yet some have mixed research in their efficacy.

muscle Pro Tip Alert!

Just because a product doesn't contain any notable ingredients doesn't mean it's bad. And a product with notable ingredients (or even many) doesn't necessarily guarantee the efficacy of the product performing these effects either. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine this.

question
lightbulb What is the Ingredient Safety Breakdown?

Ingredient Safety Breakdown refers to the percentage % of ingredients in different risk categories as classified by EWG (Environment Working Group) if they are available. There are almost endless cosmetic ingredients and they are one of the few organisations globally that have assigned ratings to a lot of the more commonly used ingredients which is why we reference them.

muscle Pro Tip Alert!

EWG is seen by many to be more on the alarmist side in their assignment of health ratings resulting in rating ingredients as riskier than they actually are. We recommend using this a reference point rather than a strict guide of ingredient safety and to always do further research if into ingredients that you may find suspect.
