According to dermatopathologist Dr. Gretchen Frieling, “Lash serums are growth-enhancing formulas that stimulate lash growth. When applied regularly, the lash serum extends the telogen phase of growth, lengthening the lash growth cycle. This will keep lashes thicker and stronger,” (via Byrdie). Formulas can have variations of proteins in them, including amino acids and peptides, that can help build up your lashes. Most of these eyelash growing serums are available over the counter. You can ask your dermatologist about Latisse, too, which is the only FDA-approved lash serum. With regular use, you’ll see results in about two months using Latisse (via Mayo Clinic).
In comparison, eyelash extensions give you immediate results post-appointment. They’re also waterproof, customizable, and painless to apply (via Byrdie). However, you will have to invest time and money with extensions — they only last about four weeks, and they don’t come cheap. They’re also sensitive to oils and any kind of rubbing and serums, and possible side effects include infection and irritation. Serums can give you similar side effects, too, so we’d recommend speaking to a provider before using either option.
