A: You absolutely need to protect your scalp from the sun. Most people can get away with using regular sunscreen on the scalp, but if this bothers you, there are sprays designed specifically for the scalp, such as Oscar Blandi Capri Sun Shield Spray.

A: You can treat yourself by creating a DIY mask for your face. Also, remember that small splurges can feel luxurious. If you’ve got $10, splurge on vegan nail polish. SpaRitual is free of DBP, formaldehyde and toluene and offers an extensive line of lacquers. Depending on where you live, you can score a manicure — that even includes a mini-massage — for under $10. (Usually, these are bigger cities, but it doesn’t hurt to call around and ask about the specials!) Or try Korres Lip Butters, deeply hydrating lip balms that double as blush and come in a variety of colors. Got $20? Splurge on an ultra-moisturizing hand cream or foot cream. Our hands are exposed regularly to environmental assaults like UV rays and chilly, windy weather, and feet take a beating on a daily basis. So pampering them is really a must! Got $30 or $40? Consider a lip gloss that also plumps your pout or an entire set of plumpers.

A: Your skin may have become accustomed to the formula. Look for formulas with higher concentrations of active ingredients. If you’re using a treatment with 2.5 percent benzoyl peroxide, go up to 5 percent. You also might consider seeing a dermatologist for a stronger prescription. Retinoids are highly effective at treating acne and they repair signs of aging and sun damage, too.

A: ATOPALM MLE Cream deeply hydrates the skin, and is perfect for those frigid, blustery days. It even helps dramatically dry skin, sensitive complexions and skin conditions such as eczema and rosacea. La Roche Posay Nutritic Ultra Fine Cream addresses four types of dryness: tightness, sensitivity, rigidity and roughness. It helps strengthen the skin’s natural barrier.
