❓ Frequently Asked Questions
Yes, this serum is safe to use during pregnancy and breastfeeding. Niacinamide (Vitamin B3) is FDA-approved and considered completely safe for topical use during pregnancy. The formula contains no retinoids, salicylic acid, hydroquinone, or other ingredients to avoid during pregnancy. It's actually recommended as a safe alternative for brightening and skin tone concerns during this time.
Yes, the simple 9-ingredient formula is fungal acne safe. It's free from ferments, problematic fatty acids, esters, and polysorbates that feed malassezia yeast. Niacinamide itself has shown anti-fungal properties in studies. This makes it an excellent choice for those with pityrosporum folliculitis.
Yes, niacinamide is compatible with most active ingredients. It pairs especially well with retinol (can reduce retinol irritation), hyaluronic acid, and peptides. For vitamin C, some experts recommend using them in separate routines (vitamin C in AM, niacinamide in PM) to maximize effectiveness, though using them together is generally safe. It can also be used with AHAs and BHAs - just introduce new actives gradually to avoid irritation.
This serum is suitable for all skin types but works exceptionally well for oily, combination, and acne-prone skin. The lightweight formula regulates sebum production and minimizes pores. Those with dry skin can still use it but should layer a hydrating moisturizer on top. Very sensitive skin types should start with once-daily use and patch test first, as 10% may be strong for some.
Results vary by concern: Initial hydration and calming effects may be noticed within 1-2 weeks. Oil control and texture improvements typically appear at 3-4 weeks. Brightening and more even skin tone become visible around 5-8 weeks. Significant fading of hyperpigmentation and lasting results usually take 8-12 weeks of consistent twice-daily use.
Apply this serum after cleansing and toning, but before heavier serums, oils, and moisturizers. The general rule is to apply products from thinnest to thickest consistency. Use 2-3 drops morning and/or evening. Allow the serum to fully absorb (30-60 seconds) before applying the next product. Always finish with SPF during the day.
No, this serum has a comedogenic rating of 0/5, meaning it will not clog pores. The oil-free, lightweight formula is specifically designed to minimize pore appearance rather than contribute to congestion. It's safe for acne-prone skin and actually helps regulate sebum production that can lead to clogged pores.
The serum has a Period After Opening (PAO) of 12 months. Store in a cool, dry place away from direct sunlight to maintain effectiveness. The 30ml bottle typically lasts 2-3 months with twice-daily use. Signs of expiration include changes in color, smell, or texture - discontinue use if you notice any of these.
Verdict: Good Molecules Niacinamide Serum delivers exceptional value with its effective 10% niacinamide formula at an unbeatable $6 price point. The minimalist 9-ingredient formula makes it pregnancy-safe, fungal acne-safe, and suitable for sensitive skin. While it lacks the added zinc found in competitors like The Ordinary, the simple formulation works well for most skin types, particularly oily and combination skin. Expect visible improvements in pore size, oil control, and skin brightness within 4-8 weeks of consistent use. A solid choice for those seeking a no-frills, budget-friendly niacinamide serum that actually works.
