Thank you for the information!
Hello Mrs.,
You did the right thing by trying products like Blistex, the basis of the treatment being hydration and other non-pharmacological measures:
An ointment or balm such as Vaseline or other balm should be applied as often as needed, depending on your preference. This should be applied whenever needed, and before and after outings among other things.
Avoid using soap on the face, clear water is sufficient and you will need to lightly tap to leave a thin layer of moisture, then apply moisturizer quickly after.
In cold weather, be sure to protect the face (scarf, neck warmer, etc.).
If the air is too dry indoors, you can also suggest a humidifier for your room. As for the sun, you should protect your skin in summer and winter with a screen with an SPF of at least 30.
Some references indicate that omega-3 supplementation could help alleviate dryness. However, these data are not yet mature.
I hope I've been helpful, and I'm available if you have any further questions!
Tom Samaha, pharmacist
