1, pay attention to the edge side cover of the bottle cap, the fake is very transparent under the light, and the genuine is much thicker.
2. Look at the edge of the fake bottle cap carefully, it is very rough and irregular, and the edge of the genuine product is very detailed.
3. Look at the difference between sunscreen lotion and liquid. The fake is light yellow, and Watson's genuine is white.
