Kelp / Laminaria Extract in winter: how to adjust
Using Kelp / Laminaria Extract in winter: the season brings cold air, indoor heating and moisture loss, so what changes is texture, frequency and what you layer around it — not usually whether you use it at all.
다시마 (dasima) is kitchen kelp, and in skincare it does what most seaweed extracts do: supplies big sugar molecules that hold water and form a soft film. Reliable as a humectant. The claims about detoxifying or delivering marine minerals into skin are decoration, not mechanism.
What winter does to your skin
Cold air and indoor heating strip moisture, so layer hydrating toners and essences under a richer cream or occlusive.
