❓ Frequently Asked Questions
Yes! This serum is completely safe for use during pregnancy and breastfeeding. It contains no retinoids, salicylic acid, hydroquinone, or chemical sunscreens. Niacinamide (Vitamin B3) is considered one of the safest active ingredients for expecting and nursing mothers. The gentle 2% concentration and clean formula make it an excellent choice for pregnancy-safe skincare.
Yes! This serum is fungal acne safe. The formula contains no ferments, fatty acids (C11-C24), fatty acid esters, or polysorbates that can feed malassezia yeast. All 8 ingredients have been verified as FA-safe, making this an excellent option for those struggling with fungal acne or pityrosporum folliculitis.
Yes, niacinamide is well-tolerated with most active ingredients! You can safely combine this serum with retinol (use niacinamide AM, retinol PM, or layer together), vitamin C (modern formulations work well together), and AHAs/BHAs. The low 2% concentration makes it especially compatible. If you experience any irritation, alternate days or use different actives at different times of day.
This serum is excellent for all skin types, but particularly shines for oily, combination, and sensitive skin. The lightweight gel texture and sebum-regulating properties make it ideal for oil control, while the gentle 2% niacinamide concentration and fragrance-free formula suit reactive skin. Dry skin types can use it but may want to layer with a richer moisturizer.
Results vary by concern: Hydration and smoothness are often noticed within 1-2 weeks. Pore refinement and sebum control typically improve around weeks 3-4. Visible brightening and fading of dark spots usually takes 6-8 weeks of consistent use. For best results, use daily (AM and/or PM) for at least 12 weeks. The lower 2% concentration provides gradual, sustainable results rather than dramatic overnight changes.
Apply this serum after cleansing and toning, but before heavier serums, essences, moisturizer, and sunscreen. The general rule is thinnest to thickest texture. A typical order would be: Cleanser → Toner → This Niacinamide Serum → Essence/Ampoule → Moisturizer → Sunscreen (AM only). Can be used both morning and evening.
No, this serum is non-comedogenic with a rating of 0/5. All ingredients have very low to zero comedogenic potential. The lightweight gel formula absorbs quickly without leaving pore-clogging residue. It's actually beneficial for acne-prone skin as niacinamide helps regulate sebum and minimize pore appearance.
The Period After Opening (PAO) is 12 months. Once opened, the serum remains effective and safe to use for one year when stored properly in a cool, dry place away from direct sunlight. The 30ml bottle typically lasts 2-3 months with daily use (2-3 drops, twice daily).
Verdict: The Mary & May Niacinamide + Chaenomeles Sinensis Serum is an excellent choice for those seeking a gentle, clean-beauty approach to brightening and sebum control. The standout 93% Chinese Quince extract provides unique antioxidant benefits you won't find in most niacinamide serums, while the conservative 2% niacinamide concentration makes it ideal for sensitive skin or those new to the ingredient. The minimal 8-ingredient formula, pregnancy/FA-safe profile, and eco-friendly packaging align perfectly with clean beauty values. While those seeking aggressive, fast results may prefer higher-concentration alternatives, this serum delivers steady, sustainable improvement with virtually no irritation risk. A solid K-beauty gem for the conscious skincare enthusiast.
