Vitamin C Serum Before & After: 1 Month Skin Results

I’ve always had a love-hate relationship with my oily skin — one day it glows, the next it breaks out. So, when I came across DERMATICA REJUVA C Serum Vitamin C Serum, I decided to try it for 30 days and document what really happens. Can vitamin C for oily skin actually help with acne scars, dullness, and texture? Here’s what I found out.

Week 1: Setting the Base Right

Before diving into any serum, I made sure my skincare base was solid. I washed my face daily using the Cetaphil face wash for oily skin, which kept my skin clean without stripping natural oils. It's gentle, fragrance-free, and perfect for prepping the skin for treatment.

For moisturising, I used the Cetaphil DAM moisturiser, which paired beautifully with the serum — lightweight but hydrating enough to maintain a balanced skin barrier.

Then came the main player: DERMATICA REJUVA C Serum Vitamin C Serum. It’s light, non-greasy, and quickly absorbed — perfect for my oily, acne-prone skin. I applied a few drops every morning, followed by sunscreen.

Week 2: Subtle Changes & Tiny Breakouts

By the end of week two, I noticed a faint brightness to my skin tone. It didn’t look drastically different, but it definitely felt fresher. That’s one of the well-known vitamin C for skin uses — it boosts glow and revives dull complexions.

I also had a couple of small breakouts, which I learned is normal when introducing potent actives like vitamin C. Luckily, they healed quickly, thanks in part to the consistent use of Cetaphil face wash for oily skin and Cetaphil DAM moisturiser, which helped maintain balance.

So to answer the common question: “Is vitamin C serum good for oily skin?” — absolutely, especially when paired with the right skincare.

Week 3: Noticeable Brightening & Fading Marks

Now things were getting exciting. My skin looked more even-toned, and the acne scars that had been lingering for months started to fade. That’s when I truly saw the vitamin C serum benefits for oily skin.

One thing I didn’t skip: vitamin C serum with sunscreen. They’re like skincare soulmates — vitamin C protects against damage, and sunscreen prevents new pigmentation. Together, they gave me a noticeable difference in sunspots and dullness.

Week 4: The Results Are In

After 30 days of consistent use, I was genuinely impressed. My skin was visibly brighter, less oily, and smoother. Breakouts were minimal, and old acne scars were visibly lighter.

If you're asking, “which vitamin C serum is best for oily skin?”, I’d confidently say DERMATICA REJUVA C Serum Vitamin C Serum is a strong contender. It’s gentle, effective, and fits seamlessly into a routine with Cetaphil DAM moisturiser and Cetaphil face wash for oily skin.

I also learned that taking care of internal health matters. Vitamin C deficiency diseases can show up as dull, dry, or inflamed skin. I added more citrus and berries into my diet to get a holistic glow from the inside out.

Why Is Vitamin C Important in Skincare?

Besides brightening, vitamin C helps neutralize free radicals, supports collagen production, and reduces pigmentation. It’s especially helpful for those dealing with oily, acne-prone skin, like me.

If you’re wondering, “what is vitamin C serum used for?”, the answer is: to brighten, protect, repair, and smooth the skin.

There are even vitamin C face serum for dry skin options if your skin leans that way. And if you’ve ever had sensitivity, don’t worry — most reactions or vitamin C symptoms on skin are mild and go away with regular use or adjusting frequency.

Final Verdict

After one month of using DERMATICA REJUVA C Serum Vitamin C Serum, my skin is healthier, clearer, and noticeably more radiant. Combined with the Cetaphil face wash for oily skin and Cetaphil DAM moisturiser, it created a routine that I’ll definitely continue.

So if you’re looking for a serum that tackles dullness, acne scars, and uneven texture — and you're wondering if vitamin C for oily skin is worth the hype — I say, go for it.
