| Alcohol Denat. | Witch Hazel (Hamamelis) | |
|---|---|---|
| What it is | The single most argued-about line on a Korean sunscreen label. Denatured alcohol is why that sunscreen feels like nothing and vanishes under makeup — it flashes off and leaves the filters behind. It genuinely stings compromised or sensitised skin. The claim that it damages a healthy barrier at cosmetic levels is far shakier than the internet suggests. | The tightening sensation is real and almost entirely temporary. Witch hazel's tannins constrict the skin surface for a while, which reads as smaller pores in a mirror. The bigger question is the distillate: many versions carry alcohol, and on already-reactive skin that combination gives you redness dressed up as freshness. |
| Best for | Oil control | Oil control, Pores & texture, Redness & sensitivity |
| When to use | BOTH | BOTH |
Which should you choose?
