10% Niacinamide Spot Correcting Serum
Post-acne marks linger due to excess melanin, inflammation, and slow skin renewal. /PHD/’s 10% Niacinamide Spot Correcting Serum is designed to break this cycle. Niacinamide regulates oil and minimizes pores, NAG accelerates skin repair, and Arbutin works to fade dark spots for a visibly clearer, more even complexion. Formulated for oily and acne-prone skin, it repairs without irritation—so you see results, not side effects.
Do's
- Apply on Clean, Dry Skin: Use the serum after cleansing and before moisturizing for maximum absorption.
- Use Daily: Niacinamide is gentle enough for daily use, even twice a day (morning and night), if your skin tolerates it well.
- Layer Wisely: It pairs well with most ingredients like hyaluronic acid, peptides, and ceramides.
- Follow with Sunscreen: If used in the morning, always follow with a broad-spectrum SPF.
- Be Consistent: Results can take a few weeks, so regular use is key to seeing visible improvements in marks and oil regulation.
Don’t
- Don’t Mix with Low pH Acids Immediately: Avoid applying niacinamide right after strong AHAs/BHAs or Vitamin C to reduce chances of flushing or temporary irritation.
- Don’t Overuse: A little goes a long way, using too much product won’t speed up results and can overload the skin.
- Don’t Skip Moisturizer: Always follow with a good moisturizer to lock in hydration and strengthen the skin barrier.
- Don’t Expect Overnight Results: Niacinamide works gradually—be patient and give it at least 4–6 weeks for post-acne marks and oil regulation to improve visibly.
- Don’t Use on Broken or Inflamed Skin: Wait until active wounds or inflamed acne calm down before applying.
