In one sentence, describe what the following article is about: “Therefore” should always be followed up with a comma. This is because there is a natural pause after “therefore” when it is included in a sentence. Without the comma the sentence may sound rushed to readers.  For example, “I love spending time in nature. Therefore I go camping every summer.” Without the comma, there is no pause after “therefore.” However, if you add the comma, then this will tell readers to pause after they read the word “therefore.” The revised sentence reads like this: “I love spending time in nature. Therefore, (pause here) I go camping every summer.” If you are using “therefore” in the middle of a sentence to separate 2 independent clauses, then you will need to use a semicolon. In other words, if each part of the sentence could stand alone as a sentence, then place a semicolon at the end of the first independent clause, follow that with “therefore,” and then place a comma after therefore before continuing the sentence. For example, “Marcus loves to travel with his family; therefore, he is constantly on the lookout for low-cost airfares.” As with any sentence, “therefore” should be capitalized if it is at the beginning of a sentence, but it does not need to be capitalized in any other instance.
Summary: Follow “therefore” with a comma. Place a semicolon (;) before “therefore” when separating independent clauses. Capitalize “therefore” when it is at the beginning of a sentence.

In one sentence, describe what the following article is about: Creams with antioxidants can be beneficial. They help absorb free radicals that can cause damage to your skin. Antioxidants to look for include vitamin C, vitamin B3, and vitamin E. These vitamins are particularly effective in a cream because they are able to be absorbed into the skin more readily than others.  A free radical is just oxygen that isn't stable.  As an added bonus, vitamin B3 helps your skin retain moisture. Though vitamin A is also an antioxidant, it does more than just work on free radicals. It can also help increase production of collagen fibers in your skin. Collagen fibers affect elasticity, meaning it can cut down on wrinkles. Retinol is a form of vitamin A, so look for that on the label. This ingredient can also help reduce wrinkles. In addition, it may help protect your skin against the sun. These ingredients mimic peptides in your skin. Specifically, they can mimic collagen or elastin, the fibers the help regulate elasticity. They encourage your skin to produce more of these molecules, which in turn helps reduce wrinkles on your skin. Certain extracts also act as antioxidants. In addition, many of them are also anti-inflammatory, helping your skin be less puffy. Two to look for are green tea extract and grape seed extract. Grape seed extract also helps you heal from skin injuries.
Summary: Look for the antioxidants. Choose one with vitamin A. Pick one with coenzyme Q10. Check for polypeptides or oligopeptides. Read for extracts.

In one sentence, describe what the following article is about: Your vet will know your pet almost as well as you do and can recommend the type of walking equipment you may need. Trust the vet’s expertise when it comes to selecting a collar and leash for your dog’s specific body type or weight. Your vet can assist you with tips to avoid neck conditions that can arise from an improper collar. There is a wide variety of collars and leashes available on the market, but not all of them are suitable for your animal. For example, a traditional buckle collar and hook leash are typically used when there is little issue with walking your dog. For those that have more difficulty with a non-cooperative pet there is a variety of more restrictive collars and leashes available.  Slip collars help keep the easily distracted dog in line. Pack leader collars are used on dogs that like to pull. Harnesses are useful on dogs with elongated necks. Special-use collars include shock collars, vibrating collars, and GPS collars. Glow in the dark collars make sure you are visible to others. Use retractable leads if you live near a large park or in the countryside so you can enable your dog to explore. This device is highly regarded as a safe and effective method for dog training. Use the clicker to reinforce good behavior and communicates in a clear, concise way to the dog. The click sound, followed by a treat, communicates to the dog that it has done the right thing. The clicker method is effective in training a dog to walk and other areas of training as well, such as barking, potty-training, and tricks. Use the clicker, followed by a treat, for the following steps:  Begin with putting the leash on. When your dog stops resisting the leash. As the dog walks behind you or beside you. Repeat periodically throughout the walk. When returning home, remove the leash. Repeat daily.
Summary:
Talk to your vet before buying walking equipment. Buy the proper collar and leash for your pet. Consider the clicker device for training.
