In one sentence, describe what the following article is about: Run the Brussels sprouts under cold water and remove any yellowed leaves. Then, cut them in half from the top to the stem, and make a 1/2 inch (1.3 cm) incision in the stem. This will help the heat penetrate the Brussels sprouts. Make sure the saucepan is large enough to hold the sliced Brussels sprouts. Season the sprouts with salt and pepper to taste. Cook them one side for about 5 minutes until they're golden brown, and then turn them over to the other side. The water should coat the bottom of the entire pan. Cook the Brussels sprouts until the liquid has evaporated and they're cooked through. Then, toss them with the lemon juice and serve them while they're hot.
Summary: Wash and cut the Brussels sprouts. Heat 1/4 cup of olive oil in a saucepan over medium-high heat. Place the Brussels sprouts in the pan sliced-side down and season them. Sauté the Brussels sprouts. Pour 1/3 cup of water into the saucepan and finish cooking the sprouts.

Problem: Article: When shopping for skincare products, look for facial moisturizers that contain collagen peptides. Collagen is a part of your skin that helps it remain moisturized and elastic. Over time, the collagen in facial skin breaks down, contributing to both sagging and wrinkles. Using a collagen cream may help replenish your skin’s natural collagen, making your skin appear tighter and more moisturized. Not all collagen creams contain the same added ingredients or percentage of collagen. When using a collagen cream, read the label carefully to see how often the cream should be applied. Vitamin C serums contain concentrated doses of vitamin C that can tighten skin, reduce sun and age spots, reduce redness, and boost the production of collagen. Unlike drinking vitamin C (which is also healthy!), serums allow your skin direct contact with the vitamin so that the benefits are absorbed right into your skin.  Vitamin C serums are safe for most skin types, so this is a great option if you have any allergies or skin sensitivities.  Serums often include other skin-tightening ingredients, including retinols, hyaluronic acid, and collagen peptides.  Most vitamin C serums are safe to use 1 to 2 times per day. However, always check the label on your vitamin C serum to see how often it is safe to use. Hyaluronic acid is a naturally-produced molecule that binds water to the collagen in your facial skin. Like collagen, hyaluronic acid breaks down over time, leaving your skin vulnerable to dehydration and sagging. Applying a hyaluronic acid moisturizer daily can help re-hydrate your skin, making it appear tighter and healthier. Hyaluronic acid is generally considered a great option for all skin types and does not usually trigger allergic reactions, break outs, or rosacea. Thus, it can usually be added to your daily skincare routine. These products work through exfoliation, meaning they cause shedding of the surface skin. Be aware that using creams with glycolic or lactic acid can increase your skin’s sensitivity to UV. If you start noticing that your skin is getting redder in the sun than before you started using this cream, stop using it and try a different treatment. Check the ingredients before you buy, because the concentration of acid should be 10 percent or less to be safe. Retinol is one of the most popular skin-tightening ingredients and can be found at almost any pharmacy, drug store, or skincare retailer. Retinol creams have been shown to help reduce wrinkles, tighten skin, and make skin damage less visible.  While retinol can be the most effective skin-tightening ingredient for some, it comes with a long list of potential side effects, including dryness, irritation, sensitivity to sunlight, redness, swelling, and blistering. Because retinols can cause irritation, it is generally recommended that you use them only 2 to 4 times per week. If you experience any side effects, decrease your usage to 1 time per week. Contact your doctor if the side effects persist or are extreme.  Retinol may also help reduce acne outbreaks.
Summary:
Use a collagen cream to keep skin supple. Try a vitamin C serum to brighten and tighten your skin. Apply a hyaluronic acid serum or cream for hydrated, plump skin. Use a cream or serum with glycolic or lactic acid to tighten skin. Use retinol to reduce the wrinkles on your face.
