  • $\begingroup$ Have you tried sculpting to add the irregularities to get that sort of rough effect? $\endgroup$

  • $\begingroup$ Hello Allen, Sure, I would like to add a logo and kind of "embossed" if it is that the actual term to displace in the model of the bottle, but I have doubts of how it would be the right approach $\endgroup$

I would definitely go the displacement route. You can achieve what you're looking for rather easily by mixing a couple of Noise Textures - one "Large" and less detailed one for the warped shape of the bottle, and another "Smaller", more detailed one for the little surface bumps. I inverted the mix and darkened it a little to make the roughness of the Material as well. I mixed the result with white before the displacement to soften the effect and make it more realistic (default "contrast" is often too strong).

Warp1

Result in Cycles (denoised):

Warp2

If you're willing to subdivide your model quite a bit (using a subsurf modifier), you can enable true displacement to make the whole bottle warp (shown below with exaggerated effect - 0.4 displacement scale) - make sure to switch to "displacement and bump" or "displacement only" in the material settings (only works in Cycles):

Warp3
