I can understand your apprehension regarding acne scars and I will try my best to answer your query in a rightful way. Acne scars are pretty challenging to treat and treatment comes with variable results. Only retinoid or glycolic acid based creams can help to some extent, but the results are very subtle and unpredictable and works for very mild scars only. Therefore, I would suggest you to go for laser therapy (Fractional Co2 laser, Non-ablative RF etc.) as it has the best results of all other treatment modalities. Moreover, if additionally treated with dermaroller or 100%TCA peel (CROSS technique), pretty appreciable results can be achieved. For dark lips use a good quality moisturizing lip balm with added sunscreen agents (SYNDROME LIP BALM).  Chat Doctor. Hope this will take care of your query.
