Does NULASTIN's 24M symbol mean two years from manufacture?
No. The brand describes 24 months after opening, as indicated by the PAO symbol. Record your own opening date and follow the label on that particular product.
NULASTIN serum dates and after-opening care
NULASTIN LASH Follicle Fortifying Serum, BROW Shape Altering Serum and HAIR Vibrant Scalp Treatment are designed for different application areas. LASH and BROW each contain 3 mL, but their applicators and formulas differ; keep the exact product name with its package markings.
NULASTIN FAQ
Is a thick NULASTIN BROW serum necessarily old or spoiled?
No. BROW is intentionally thick to stay in place, and some resistance when removing the brush can be normal. Unexpected changes or irritation still warrant stopping use.
Should HAIR Vibrant Scalp Treatment be rinsed out like the shampoo?
No. The scalp treatment is left on after application to dry or towel-dried hair. Vibrant Scalp Shampoo and Conditioner have separate rinse-out directions.
NULASTIN: production date, opening date and supply duration
Before you rely on the decoded date
- If your package has a clearly labelled MFG date, read it as the manufacturing date. Keep a neighbouring LOT separately for product identification and enquiries; do not combine the two fields.
- NULASTIN describes a typical serum supply as four to six weeks when used as directed. That estimates how quickly the contents are used up, not a manufacturing date or an instruction to discard every tube after six weeks.
Common lookup mistakes
- Apply LASH before mascara, not over it, to avoid contaminating the applicator. The product directions specify the upper lash line and advise against the lower lash line; avoid direct eye contact.
- Store unopened products in a cool, dry place away from sunlight. NULASTIN says refrigeration is optional and warns against freezing its serums.
