Offer to take your mother-in-law out for coffee or lunch and ask to discuss the issue when the two of you sit down. Start by explaining that you aren't angry or upset, but simply want to understand why she's being so critical. There may be an underlying issue that is bothering her, and discussing the problem in a collaborative way will get you closer to solving the problem. Start by making it about you. Say, "I'd love to sit down with you and talk through something that's been bothering me lately." This will make it seem like you have a problem, not her, and will prevent a potential argument. If your mother-in-law critiques your style or beliefs, play her comments off like she's making a suggestion, not an objective comment. This will undermine your mother-in-law's comments by making them seem like they're entirely a matter of opinion. It will also relieve tension a little bit by making it easier to move on in the conversation. "I guess I'll have to think about that," "That's an interesting perspective," and, "I see where you're coming from, let me think about it," are good responses that will make it seem like there's nothing more to say. If your mother-in-law comments or critiques something relating to your religion, culture, political beliefs, or class, create a firm boundary by calling her out. If you consistently show her that you're unwilling to tolerate her comments, she'll be forced to confront her unfair beliefs and defend them. If she doesn't want to do that, which is the more likely response, she'll simply lay off of the sensitive subjects. Be firm, but respectful. For example, if your mother-in-law says you need to start going to church, say, "I don't criticize your religious beliefs and you have no right to criticize mine. I will not tolerate you tearing me down. Please stop now and we can move on."

Use the attachments on your vacuum to sweep the cracks and crevices of the furniture. Remove any cushions and vacuum away all visible dirt. Use the soft brush attachment to clean the surface of the furniture, too. Always use the vacuum attachments rather than picking up the entire vacuum and putting it on the furniture. The weight of the vacuum and its sharp edges could easily scratch the leather. Use a clean, dry microfiber cloth to give the entire piece of furniture a thorough wipe down. Start at the top of the furniture and work your way down so that any dislodged dust or dirt will fall to areas that haven't been wiped clean yet. While you're wiping the furniture down, take note of any areas that are stained or particularly dirty so you can treat them later. In a small bowl, combine 12 cup (120mL) of water with 12 cup (120mL) of white vinegar. To prevent spilling the mixture, place the bowl on the ground near the furniture that you're cleaning. Test out new cleaning products on an inconspicuous area first just in case it doesn't react well with the leather. Dip a clean microfiber cloth into the solution and squeeze it out so that it's damp, but not dripping. Use a gentle, circular motion to clean away dirt and grime. It's not necessary to clean the entire piece of furniture, though it won't hurt the leather to wipe the whole thing down. Be very gentle if you're cleaning unprotected leather, as it is much easier to scratch and damage. After you wipe down the piece of furniture, take a clean, dry microfiber towel and wipe away any excess moisture that remains. Avoid letting wet spots air dry. If the microfiber cloth gets too wet while you're drying off the furniture, use a fresh, dry towel. Read the manufacturer's instructions carefully before you apply the conditioner. Generally, you'll apply the conditioner to a clean washcloth and rub it into the leather using gentle, circular motions. Make sure to check how long the conditioner needs to be left alone before you use the furniture again. Test the conditioner out on an inconspicuous area of the furniture before applying it to the entire piece.

Get the kind of lip gloss that comes with a wand applicator. Do not use the kind that you have to squeeze to get out. Set the wand applicator aside, preferably on a plate so that your table won't get sticky. Both cinnamon essential oil and peppermint essential oil have lip-plumping abilities. They help improve blood circulation to your lips. This may help make your lips appear fuller. Cinnamon oil can be irritating. Consider mixing a drop or two with some oil (such as olive oil) and dabbing it on your inner elbow. If it doesn't irritate your skin, you're good to go. You can also pump the wand applicator up and down in the tube a few times to mix the oil into the lip gloss.
