How to Layer Serums Without Wasting Product

A common mistake: applying three serums at once, all in a thick layer, and wondering why nothing seems to absorb. The rule of thumb is thinnest-to-thickest, with a short wait between layers — 30–60 seconds is usually enough.

Ampoules are more concentrated than serums and are meant to be used in smaller amounts — a few drops go a long way. Save your priciest ampoule for the layer right after toner, when skin absorbs the most.

Not every active needs to go on every day. Alternate brightening and exfoliating actives with calming ones (like Centella) so your skin barrier gets a break — especially important if you're also using sunscreen daily, which most of Bangladesh's climate demands.
