π¬ Ingredient Breakdown
πΆ Galactomyces Ferment Filtrate 60% Proven
A yeast ferment (similar to SK-II's Pitera) that brightens skin, minimizes pores, reduces sebum production, and improves overall skin texture and radiance.

- Synergy: Works synergistically with niacinamide for enhanced brightening
π Snail Secretion Filtrate Promising
Italian-sourced snail mucin rich in glycoproteins, hyaluronic acid, and peptides. Supports skin regeneration and helps smooth textural irregularities.

β Frequently Asked Questions
Use with caution. While topical niacinamide and tranexamic acid are generally considered safe during pregnancy (Category B), Niacid contains snail mucin and galactomyces ferment which have limited safety data for pregnant/nursing mothers. Consult your healthcare provider before use.
No, Niacid is NOT safe for fungal acne. It contains 60% Galactomyces Ferment Filtrate, a yeast-derived ingredient that can feed Malassezia and worsen fungal acne. If you have malassezia folliculitis, consider alternatives like Good Molecules Discoloration Correcting Serum or The Ordinary Niacinamide 10% + Zinc 1%.
Yes! Niacid pairs well with most actives. Niacinamide and vitamin C can be used together despite old myths. For retinol/AHA/BHA, apply Niacid first, wait a few minutes, then apply the other active. Alternatively, use them at different times of day (Niacid AM, actives PM or vice versa).
Niacid is formulated for all skin types including sensitive skin. It's especially excellent for oily, combination, and acne-prone (non-fungal) skin. The oil-free, fragrance-free formula won't clog pores or cause irritation. Dry skin types can use it but should follow with a richer moisturizer.
Many users notice an immediate brightness boost overnight. Fading of blemishes and healing of indentations typically becomes prominent during days 3-7 and continues improving cumulatively. Significant results for hyperpigmentation usually appear within 2-4 weeks with consistent use. Full transformation may take 2+ months.
Apply Niacid after cleansing and toning, as step 3 in your routine. Dispense 3-6 drops onto palms and press into skin. Follow with serums, moisturizer, and sunscreen (AM). Niacid can be used both morning and night. Always use SPF during the day to protect healing skin.
No, Niacid has a low comedogenic rating of 1/5. The oil-free formula is designed to absorb fully without clogging pores. It's safe for acne-prone skin (non-fungal type). The transdermal technology actually helps the formula penetrate rather than sit on top of skin.
Niacid has a PAO (Period After Opening) of 12 months. Store in a cool, dry place away from direct sunlight to maintain efficacy. The glass dropper bottle helps protect the formula from degradation. If you notice any changes in color, texture, or smell, discontinue use.
Verdict: Slurp Niacid is an innovative K-beauty serum that delivers on its promise to fade acne scars and brighten skin. The unique transdermal technology and powerhouse combination of 60% Galactomyces, niacinamide, tranexamic acid, and snail mucin make it a standout product for those dealing with PIE/PIH. While the premium price and unsuitability for fungal acne are drawbacks, the fragrance-free, oil-free formula with visible results makes it worth the investment for the right skin concerns.
