A: Wrinkles are a natural result of aging, but you can delay their onset or minimize their appearance. To do so, limit sun exposure, wear sunscreen every day, and use skin products that contain antioxidants and retinoids, which can reduce fine lines and wrinkles.

A: Since sun damage increases the risk of skin cancer, as well as skin problems ranging from wrinkles to dark spots, wearing sunscreen on a daily basis is essential. Choose a broad-spectrum sunscreen with a minimum sun protection factor (SPF) of 15. Beyond that, it takes just a few minutes each morning and each evening to do the basics: washing with a gentle cleanser and applying a moisturizer to your face and neck.

A: UV exposure and hormonal changes are two causes of dark spots. Avoiding the sun and wearing sunscreen can prevent new dark spots from forming, while exfoliating regularly or using prescription medications may help treat the existing spots you already have. Certain dark spot correctors or moisturizers may also make a difference over time. Remember to choose the products that are formulated for your skin type.

A: Be gentle with it! Always wash sensitive skin gently, and never use harsh cleansers. Avoid products that contain irritating substances. Instead, seek out those that are specifically labeled for sensitive skin.

A: An uneven skin tone is caused by an uneven distribution of pigment. Sun exposure and hormonal changes can also contribute to this issue. Certain serums, creams or moisturizers, especially those that contain vitamin C, can all help to even out your skin tone. It is also possible that your skin can develop an uneven tone due to a buildup of dead skin cells. If that is the issue, a simple way to even out your skin tone is to exfoliate once a day or every couple of days.
