Why consumers buy
Price-to-concentration value
Reviewers repeatedly cite the extremely low price for a 20% niacinamide concentration, often comparing it favorably to The Ordinary and other pricier niacinamide serums.
Repurchase / brand loyalty
Many reviewers mention being on their 2nd, 3rd, or even 10th empty bottle, and several state they buy 'all Derma Factory products' as trusted repurchases.
Influencer and word-of-mouth recommendation
Purchases were frequently prompted by Instagram influencers, YouTube reviews, Korean dermatologist endorsements, or recommendations from Korean friends.
Targeted pigmentation/dark spot treatment
A notable segment buys specifically to treat pigmentation on elbows, knees, underarms, buttocks, and scars, rather than as a general face serum.
High niacinamide reputation for brightening/pore care
Consumers associate niacinamide with tone-evening, pore-tightening, and sebum control, and chose this product to add niacinamide affordably to their routine.
How they use it
Face and body dual-use
While marketed as a facial serum, many reviewers apply it to elbows, knees, underarms, neck, and buttocks specifically to fade pigmentation and dark, rough skin.
Skin concerns raised — and how the product addressed them
✓Many reviewers applying the serum to elbows, knees, underarms, and facial dark spots report gradual lightening with consistent use, though several say results were less dramatic than hoped.
✓Frequent reports of brighter, more even-toned skin and a 'glow' after weeks of regular application, especially when used both morning and night.
✓Users note visibly smaller, tighter-looking pores and smoother texture around the nose and T-zone with continued use.
Sentiment breakdown
Share of analyzed reviews by overall sentiment.
AM/PM layering
Used both morning and night, typically after toner and before moisturizer or sunscreen; several note it absorbs quickly enough to wear under makeup.
Mixed into other products
A common technique is mixing a pump into moisturizer, cream, or body lotion to dilute the high concentration and reduce stickiness or irritation risk.
Cotton pad/pack application
Some reviewers soak a cotton pad with the serum and use it as a targeted mask ('pack') on trouble areas like the nose or pigmented patches.
Long-term, multi-bottle consistent use
Because visible brightening/tone results are described as gradual, many reviewers commit to using multiple bottles over weeks or months before judging efficacy.
✓Reviewers report reduced midday shine and better oil control, particularly for combination and oily skin types.
✓Most sensitive-skin users tolerate the formula well and describe it as gentle, though a minority experienced stinging, especially on broken skin or with overuse of the high concentration.
