Vitamin C Serum

Yes, Mad Hippie Vitamin C Serum is considered pregnancy and breastfeeding safe. The formula does not contain any of the ingredients typically flagged during pregnancy: no retinoids (retinol, retinaldehyde, tretinoin), no salicylic acid, no hydroquinone, no chemical UV filters, and no formaldehyde-releasing preservatives. The key active, Sodium Ascorbyl Phosphate (SAP), is a safe and gentle form of Vitamin C. As always, we recommend consulting with your OB-GYN or midwife before introducing new skincare products during pregnancy.

Yes — Mad Hippie Vitamin C Serum is fungal acne safe. An independent analysis by Folliculitis Scout confirms zero fungal acne triggers in the formula. The product contains no fermented ingredients, no fatty acid esters that feed Malassezia yeast, and no polysorbates. Alkyl Benzoate (C12-15 Alkyl Benzoate) in the formula is a benzoate ester, not a fatty acid ester, and is not a documented Malassezia trigger. The Konjac Root also has documented antifungal properties. This makes the serum an excellent choice for those managing fungal acne or Malassezia folliculitis.

Yes — and this is one of the biggest advantages of using SAP over L-Ascorbic Acid. Because SAP does not require a low pH to be effective, it is far more compatible with other actives. You can layer it with niacinamide, AHAs (glycolic acid, lactic acid), BHAs (salicylic acid), and retinol without worrying about pH conflicts or inactivation. For a morning routine: apply the Vitamin C Serum after cleansing, then moisturizer and SPF. For evening routines with retinol, apply Vitamin C first, wait for it to absorb, then follow with your retinol product. Start slowly if combining multiple actives and patch test any new combination.

Mad Hippie Vitamin C Serum is particularly outstanding for sensitive, acne-prone, and oily skin types — arguably the best Vitamin C serum available for these skin types. Its 0% irritation rate in clinical testing and SAP's natural antimicrobial activity against P. acnes make it uniquely suited for reactive and breakout-prone skin. It also works well for normal and combination skin. For dry skin types, the serum provides good hydration from Hyaluronic Acid and Glycerin, but you may need a more nourishing moisturizer on top. Mature skin types benefit from the antioxidant and collagen-supporting properties, though they may also want to pair this with a dedicated retinol product for enhanced anti-aging results.

Most users notice an initial improvement in skin glow and radiance within the first 1–2 weeks. A more noticeable improvement in skin texture, tone evenness, and reduced redness typically becomes visible around weeks 3–4. For significant brightening, dark spot fading, and discoloration reduction, the 6–8 week mark is the key milestone — in Mad Hippie's own clinical study, 94% of participants saw measurably softer and brighter skin with less discoloration at 8 weeks of consistent daily use. Full collagen-supporting and long-term anti-aging benefits continue to accumulate over 3+ months of regular use. Consistent daily application is essential for optimal results.

Apply Mad Hippie Vitamin C Serum as your 3rd step — after cleansing and toning, but before heavier products like eye cream, moisturizer, and sunscreen. The general rule is to apply products from thinnest to thickest consistency. The serum's lightweight gel texture means it should always precede heavier creams and oils. In the morning, always follow with a broad-spectrum SPF 30+ — Vitamin C enhances the effectiveness of sunscreen and together they provide compounding photoprotection. The serum can also be used in your PM routine if you're not using another treatment serum at night. Avoid using it at the same time as a separate oil-based serum in the same step.

Mad Hippie Vitamin C Serum has a comedogenic rating of 1/5 — considered non-comedogenic. The formula is water-based with no heavy oils, waxes, or high-comedogenic ingredients. Glycerin, Hyaluronic Acid, and Konjac Root are all rated 0 on the comedogenic scale. C12-15 Alkyl Benzoate is a light emollient that rates 1-2 on most comedogenic scales but at the concentration used in this formula does not pose a significant pore-clogging risk for most users. Independent analysis by Folliculitis Scout confirms the formula does not trigger fungal acne. The brand explicitly markets this product as suitable for congested and acne-prone skin types.

Mad Hippie Vitamin C Serum has a Period After Opening (PAO) of 12 months. Because it uses Sodium Ascorbyl Phosphate — one of the most oxidation-stable forms of Vitamin C — rather than pure L-Ascorbic Acid, it has a much longer shelf life than most Vitamin C serums. In practice, because only 2–4 drops are needed per application, many users report their 30ml bottle lasting 6–10 months of daily use. Store in a cool, dark place (or refrigerator) to maximize longevity. If the serum changes color from its natural pale yellow to a dark orange or brown, it has oxidized and should be replaced.
