FAQ to this Product
Which skin types is this serum suitable for?
Niacinamide is particularly interesting for oily skin, visible pores and uneven-looking skin tone. Suitability also depends on the concentration and complete product formulation.
How and when should I apply this serum?
Apply the serum in the evening to cleansed skin. Gently spread 2–3 drops over your face and allow the serum to absorb. Follow with a suitable moisturizer if needed.
How often should I use this serum?
Start by applying the serum 2–3 times per week. Once your skin becomes accustomed to the formula and tolerates it well, gradually increase the frequency of use.
Which other serums can I combine it with?
Niacinamide can often be combined with hyaluronic acid or vitamin C. It may also complement a retinol routine, depending on the concentrations and the overall tolerance of your skincare products.
Which ingredient combinations should I avoid?
Niacinamide is not inherently incompatible with vitamin C or retinol. However, avoid introducing several high-strength serums or intensive exfoliating products at the same time.
Can I use this serum morning and night?
Evening use is recommended for this serum. Frequency can be increased gradually as your skin develops tolerance. During the day, complement your routine with moisturizing care and sunscreen.
How long does it take to see results?
A more balanced-looking complexion may develop after several weeks of regular use. Niacinamide may improve the appearance of visible pores but cannot permanently reduce their actual size.
Which DS V-LINE products complement my routine?
Pair your niacinamide serum with SucraEx Barrier Repair Cream for moisturizing care. Finish your morning routine with Lumea SPF50 Sunscreen Cream .
