Although aging doesn't usually become too visible until your early 40s, you might begin to develop wrinkles in your 30s due to genetic or environmental factors. According to the American Academy of Dermatology, there are two types of skin aging -- intrinsic and extrinsic 2. Intrinsic aging is your skin's genetic predisposition, and extrinsic aging is related to environment, sun exposure and other variables. While there's little you can do to turn back the hands of time, you may be able to prevent or slow premature extrinsic aging with the right skin care regimen.

Avoid excessive sun exposure. You may already be aware that exposure to ultraviolet rays can contribute to premature aging. According to dermatologist Elizabeth Tanzi, Dr.Oz.com, many of the earliest visible signs of aging such as wrinkles, brown or red spots and dull skin, aren't due to aging -- but to sun exposure or other lifestyle factors. Tanzi recommends you protect your skin against the sun by using a sunscreen with an SPF of at least 30.

Seek out quality skin creams. Tanzi says it's important to sift through the countless "anti-aging" skin care products on the market and focus on quality. Prescription-strength retinoid products such as tretinoin and tazarotene, are thought to be highly effective anti-wrinkle agents, according to Tanzi. However, the potential redness and irritation caused by these products might not be tolerable to all skin types.

Investigate treatment options. The American Academy of Dermatology reports that if you want to take stronger measures to reverse wrinkles in your 30s, you can investigate medical procedures that may achieve this result 2. Currently, many dermatologists offer procedures such as dermal fillers, botulinum toxin, microdermabrasion, chemical peels and more. Many of these procedures require minimal downtime and may temporarily revitalize your skin. You can also talk to a dermatologist about prescription-strength skin creams.

Implement a skincare regimen. Smooth on a thin layer of a serum or targeted cream both morning and night to revitalize skin and minimize the appearance of wrinkles. To remove any dead skin cells and treat dullness, exfoliate skin before bedtime with a moisturized skin brush or dampened washcloth.

Tips

Wear hats or other protective clothing to cover up skin.

Dermatologist Rosemarie Ingleton says on the Today Show website that antioxidants can combat wrinkles caused by extrinsic aging factors such as cigarette smoke and pollution. Ingleton recommends antioxidants like idebenone, coenzyme Q10, vitamins C and E.

Warnings

Refrain from doing "facial exercises." The American Academy of Dermatology emphasizes that exercising your face to prevent aging generally has the opposite effect. By repeatedly making certain facial expressions, you may be inviting fine lines and wrinkles.
