Why your vitamin C serum may stop working — and what to do about it
Quick Answer
Eve Hansen Vitamin C Facial Serum is formulated with vitamin C, an antioxidant that may help support a more even, brighter-looking complexion over time. Used consistently as a step 3 serum, it may help skin appear more radiant. Most people notice visible changes after 4–6 weeks of regular use as part of a complete routine.
Dark spots, post-acne marks, melasma, sun damage — hyperpigmentation takes many forms but the frustration it brings is consistent. It affects confidence, leads to spending on products that are not targeted enough, and creates a cycle of routine-hopping that never quite delivers. A consistent, correctly layered approach using the right ingredients may help improve the appearance of uneven skin tone over time.
Why does this skin concern happen?
Hyperpigmentation occurs when melanin — the pigment that gives skin its colour — is overproduced in certain areas. Triggers include UV exposure, post-inflammatory response from acne or injury, hormonal changes, and aging. The result is patches or spots that appear darker than surrounding skin.
What does the key ingredient do?
Vitamin C is widely used in cosmetic skincare to help support a more even-looking complexion. As an antioxidant, it may help skin appear more uniform in tone over time.
Eve Hansen's Rosehip oil, rich in essential fatty acids, is an excellent complementary ingredient that helps support the appearance of more even, deeply nourished-looking skin.
How Vitamin C Facial Serum may help
The Vitamin C+E Serum is applied as a targeted treatment step — after cleansing and toning, before moisturizer. Its serum texture allows active ingredients to work effectively. Used daily as part of a complete brightening routine, it may help support a more even-looking complexion over time.
"Consistency is the most important factor. Using Eve Hansen Vitamin C Facial Serum daily as part of a complete targeted routine is what produces cumulative, visible results in how skin looks and feels over time."
The complete routine
Targeting this concern effectively requires a layered approach — each step supporting the next.

Eve Hansen Pro Tip
Consistency is everything with hyperpigmentation. Most people need 8–12 weeks of daily use before noticing visible improvement. Daily SPF is essential — UV exposure drives new pigmentation formation faster than any serum can address.
Frequently Asked Questions
How long does it take to see improvement in dark spots?
Most people notice changes after 8–12 weeks of daily use. Post-acne marks may respond more quickly than deeper pigmentation.
Does vitamin C help with all types of hyperpigmentation?
Vitamin C is used cosmetically to help support a more even-looking complexion. Effectiveness varies by pigmentation type and individual skin response.
Do I need SPF alongside a brightening routine?
Yes — SPF is the most important complementary step. UV exposure actively contributes to pigmentation formation.
Can I layer vitamin C and rosehip oil?
Yes. Apply vitamin C products first, allow to absorb, then apply Eve Hansen Organic Rosehip oil as the final PM step to seal in layers beneath.
Is a brightening routine suitable for all skin tones?
Yes. Hyperpigmentation affects every skin tone and ethnicity. A cosmetic brightening routine is appropriate across all skin types and tones.
