FAQs

CAN I USE THIS IN THE AM OR PM? Both! It’s safe and effective morning and night.

CAN I LAYER IT WITH OTHER ACTIVES? Yes - but avoid using with high-strength Vitamin C (like our 30%) and exfoliating acids (AHAs, BHAs, PHAs). Safe to use with our 15% Vitamin C + EGF.

CAN I USE THIS WITH RETINOL? Absolutely. Apply Niacinamide before Retinol to help reduce potential irritation.

IS IT GOOD FOR DRY SKIN TOO? Yes! It helps balance oil production, making it great for both dry and oily skin types.

WHAT’S THE % OF NIACINAMIDE? 10%

SHOULD I USE THIS OR THE 20% NIACINAMIDE SOLUTION? If you have oily skin all over, go for our 20% Niacinamide. For combination or t-zone oiliness (and no active breakouts), stick with the 10%.

WHAT’S THE PH LEVEL? 6.09 HOW LONG UNTIL I SEE RESULTS? Give it 4–6 weeks of consistent use. More isn’t always better - overuse can cause irritation.

WHY ISN’T THIS PRODUCT VEGAN? It contains one egg-derived ingredient.

IS THE SQUALANE ANIMAL DERIVED? No - it’s plant-based.

IS IT SAFE FOR PREGNANCY OR BREASTFEEDING? Yes

CAN I USE THIS WITH PRESCRIPTION TREATMENTS? Check with your doctor first.

Super effective & lightweight!
Great for my sensitive skin- other niacinamide serums I've tried have had added products that irritated my skin, but this was perfect. No weird residue left and is super lightweight and feels great on the skin. Saw results after 2-3 days of use.
