Hello Roni,
How are you?
The 'cracking' you talk about is mostly as a result of two things;
1.not exfoliating your skin
2. using too much products (foundation or concealer)
3. not setting your makeup with powder afterwards or using too much powder.
My advice is to try and exfoliate your face at least twice a week because this will remove any dead cells on your skin and allow for new smooth skin to show.
Don't pack on too many products when doing your makeup, start with a little, then build up accordingly and always remember to blend properly so it looks and feels natural.
After applying your foundation and/or concealer, you should always go back and apply /set with powder. you can use either a loose or pressed powder. Use just a little bit to keep your makeup from shifting around and settling into lines on the face that end up looking like cracks.
If you do these three things, you should see a huge difference.
Let me know if you have any more questions,
Stacey.
