⏱ 1 min read
⚡ Quick answer: Using Amino Acids (NMF) 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.

Using Amino Acids (NMF) 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.

Amino acids do double duty in Korean routines: as humectants in essences, and as the basis of the low-pH amino-acid cleansers that replaced squeaky foaming washes.

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.

How that changes Amino Acids (NMF)

Winter is when barrier support outranks everything. Actives that were comfortable in August frequently are not in January. Amino Acids (NMF) works on dehydration (water-poor skin), damaged moisture barrier, reactive & easily-stung skin, and it is normally applied BOTH.

What to layer it with

💧 Glycerin💧 Hyaluronic Acid🧱 Ceramides🩹 Panthenol (Pro-B5)
