HOW DO YOU USE NIACINAMIDE SERUM? Apply 2-3 drops to clean skin, gently pat in, wait 1-2 minutes, then follow with moisturiser. Use after cleansing but before thicker serums or heavier creams - the correct order is cleanse, hydrating serum, niacinamide, moisturiser, then SPF for daytime routines.

WHEN SHOULD YOU USE NIACINAMIDE SERUM? Use morning, evening, or both - it's particularly beneficial in the morning under SPF for all-day oil control, and at night for overnight blemish repair. Oily skin can use twice daily, while sensitive skin should start with evening use only.

CAN YOU USE NIACINAMIDE EVERY DAY? Absolutely! Niacinamide is gentle enough for daily use and works better with consistent application since you won't build tolerance like with acids or retinol. Daily use provides continuous oil control, pore refinement, and blemish prevention.

CAN I LAYER IT WITH OTHER ACTIVES? Yes, but avoid mixing with high-strength Vitamin C and exfoliating acids in the same routine step. It's perfectly safe with our 15% Vitamin C & EGF Serum, retinol, hyaluronic acid, and peptides - just apply niacinamide first.

CAN I USE THIS WITH RETINOL? Absolutely! Apply niacinamide before retinol to reduce potential irritation and make your retinol routine more comfortable. This combo is particularly effective for acne-prone skin since niacinamide preps your skin barrier and minimizes retinol sensitivity.

WHAT DOES NIACINAMIDE SERUM DO? Niacinamide serum regulates oil production, reduces blemishes and pore appearance, calms redness, and strengthens your skin barrier for clearer, healthier-looking skin. This vitamin B3 ingredient controls excess sebum and reduces inflammation without harsh side effects.

HOW LONG DOES NIACINAMIDE TAKE TO WORK? You'll notice oil control within 1-2 weeks, but allow 4-8 weeks for significant blemish reduction and pore refinement. The timeline progresses from immediate oil control to fewer breakouts around week 3-4, then visible pore improvement by weeks 6-8.

IS IT GOOD FOR DRY SKIN TOO? Yes! Niacinamide balances oil production rather than stripping it away, making it perfect for dry skin that gets congested or combination skin types. It strengthens your skin barrier and improves moisture retention - layer with our Hyaluronic Acid Serum for extra hydration. 

WHAT'S THE % OF NIACINAMIDE? This serum contains 10% niacinamide, the optimal concentration for effective oil control, pore appearance, and blemish reduction without irritation. Clinical studies show 5-10% niacinamide provides maximum benefits while being gentle enough for daily use on most skin types.

SHOULD I USE THIS OR THE 20% NIACINAMIDE SOLUTION? Choose based on your needs: oily skin all over = 20% Niacinamide for maximum oil control, but combination skin, t-zone oiliness, or no active breakouts = stick with 10%. The 10% is better for sensitive or acne-prone skin since it's gentler while still highly effective.

WHAT'S THE PH LEVEL? The pH is 6.09, optimal for niacinamide stability and skin compatibility. This slightly acidic pH ensures maximum ingredient effectiveness while being gentle enough for daily use and compatible with other skincare products.

IS IT SAFE FOR PREGNANCY OR BREASTFEEDING? Yes, completely safe since niacinamide is vitamin B3, which your body naturally produces. It's one of the safest active ingredients for expecting and nursing mothers wanting clear, balanced skin without risk. Learn more about pregnancy safe skincare here.

CAN I USE THIS WITH PRESCRIPTION TREATMENTS? Check with your doctor first, but niacinamide typically works well alongside prescription acne and anti-aging treatments since it's gentle and can help reduce irritation.

WHY ISN'T THIS PRODUCT VEGAN? This contains one egg-derived ingredient, but our 20% Niacinamide Solution is fully vegan and cruelty-free. Both deliver effective oil control for different skin needs.

IS THE SQUALANE ANIMAL-DERIVED? No, it's plant-based squalane derived from sustainable sugarcane, making it cruelty-free and environmentally friendly.
