Dry skin is identified as skin severely lacking natural oil and moisture. Characteristics include roughness, flakiness, tightness, fine pore redness, pronounced fine lines around the eyes and mouth, and a thin, fragile texture. The skin may also appear flaky, ashy or dull from dead skin build up.

Daily Skin Care Regimen
If you have dry skin, you will need moisturizing products that nourish, so you will want to find protective and restorative products. Achieving a moisture balance with the right pH is key.

Begin with a very mild soap, possibly cream based. Since your skin is acidic, the alkaline in soap can easily disturb the delicate pH balance. Also, make sure that the soap does not contain harsh chemicals which will also remove the acid mantel and cause further dryness. Choose a toner that soothes and nourishes your skin. It should refresh with a hint of moisture—a low or no alcohol formulation is recommended to prevent over drying the skin.

A daily moisturizing routine is essential for dry skin. Begin with a serum to enhance moisture, then apply a day moisturizer. Try to use a day cream with an SPF Your evening ritual can include a serum application and a heavier moisturizer. Eye creams and serums are recommended for the delicate area around the eyes that are subject to fine lines and wrinkles.

Weekly Skin Care Routine
Use an extremely mild exfoliator in order to expose fresh skin and allow products to penetrate deeper. This will maximize the effectiveness of your skin care products. A moisture-enhancing mask that you put on and wipe off will moisturize and plump dry and dehydrated skin.

Product Recommendations:

  • Makeup remover
  • Cleanser, mild or cream based
  • Toner (low or no alcohol)
  • Morning moisturizer with SPF
  • Evening moisturizer
  • Eye moisturizer
  • Serum
  • Mild exfoliant
  • Moisture enhancing mask

    Why Moisturize?
    Everyone can benefit from using a moisturizer after cleansing. The key is finding the appropriate moisturizer based on your skin type. Moisturizers seal moisture into the skin, so the effect is hydrating while also inhibiting evaporation. Many moisturizers contain active ingredients that deliver vitamins, minerals, antioxidants and skin supporting compounds to provide therapeutic benefits that sooth, protect and ultimately help delay the onset of early aging.
    Eye creams are optional, but may be desirable for those with dry or aging skin as a welcome addendum to a moisturizer. Some individuals have very delicate eye areas that are more susceptible to wrinkling, dark circles and puffiness. An eye cream can help address these specific concerns with intense moisture and a high concentration of active ingredients.

    How to Choose a Moisturizer
    The oilier your complexion, the lighter and more liquid your moisturizer should be. Some moisturizers even have oil free ingredients that still serve to moisturize the skin without adding oil. Conversely, dry or aging skin requires a more moisturizing-nourishing preparation. Use a moisturizer labeled with your skin type or specific skin concern. If you live in a particularly harsh climate, consider wearing a more moisturizing face cream during the winter and switch to a lighter formula during warmer months.
    Night creams tend to be thicker and more moisturizing than day creams. It is generally recommended to have separate moisturizers simply for the fact that you will want a day cream with a Sun Protection Factor (SPF). This will provide you with added protection from sun damage that can lead to premature aging.
    Based on the amount of time you spend outside on any particular day, you might want to wear a moisturizer designed for outdoor use with a significantly higher SPF. You must also factor in how easily your skin burns and take precautions to protect your skin with a sufficient SPF. As a general rule, it is recommended that your day moisturizer should have at least 15-20 SPF, and if you spend more time outdoors, consider a moisturizer with 30+ SPF.

    How to Use Moisturizer
    After you wash your face and apply toner or a serum (optional), scoop out enough moisturizer to comfortably cover your face and neck area. Using your fingertips, rub it in using upward strokes, making sure to moisturize the neck, décolletage and earlobes. In order to prevent streaks, allow your moisturizer to penetrate before applying foundation.

    After you wash your face and apply toner or a serum (optional), scoop out enough moisturizer to comfortably cover your face and neck area. Using your finger tips, rub it in using upward strokes, making sure to moisturize the neck, décolletage and earlobes. In order to prevent streaks, allow your moisturizer to penetrate before applying foundation.

    Sun Protection
    SPF is an acronym for Sun Protection Factor. The Sun Protection Factor in products can range from 2-60, referring to its level of ability to block the sun's rays. Many variables should be considered when determining the level that is right for you. They include duration of exposure, time of day, season, activities you're doing, geographic location/altitude, prescription drugs that could leave you more susceptible to exposure, and your own skin's predisposition.

    Zinc oxide and titanium dioxide are both considered to be physical sunscreens or sunblocks, as they protect against both UVA and UVB radiation. UVA and UVB represent different waves on the electromagnetic spectrum of ultraviolet (UV) light. While UVB can cause sunburn and damage to the eyes, UVA can cause long term damage to the skin.

    Look for products that offer protection from both UVA and UVB rays. UVB rays are especially intense during the summer and UVA rays are present year round.

    There are two basic types of sunscreens/sunblocks. Depending on their ingredients, they work to either reflect or absorb the sun's rays. Inorganic particles like zinc oxide and titanium dioxide create a physical barrier to block out the rays, whereas organic particles absorb UV rays and release the energy as heat.

    Both sunblock and sunscreen are similar in use, but are slightly different in their protective abilities. Sunblock is more opaque and therefore protects more from UVA/UVB and radiation. Sunscreen tends to be more transparent and therefore needs to be reapplied more often. For this reason, it is recommended to choose a higher SPF since its ingredients break down more rapidly than sunblock.

    It's important to protect your face from the sun's harmful rays on a daily basis. Sun exposure is reflected and intensified by the pavement, snow, water and sand. Higher SPF is recommended for higher elevations and locations closer to the equator. It is also recommended to wear an SPF of 15 or higher regardless of your activity or weather condition.

    Increase the SPF when your sun exposure peaks, such as in the summer or during vacations. Apply sunscreen/sunblock according to its directions. Most directions indicate applying approximately one ounce of sunscreen at least 15-30 minutes before sun exposure. Make sure to reapply at least every two hours throughout your exposure, especially after perspiring, toweling or swimming.

    Be particularly cautious between the hours of 10:00 a.m. and 4:00 p.m. Limit your exposure outside, wear sunscreen, and spend time indoors or in the shade under an umbrella/structure.

    Even if you're not spending significant time outside, it's important to wear products with SPF to protect your skin. Choose a day moisturizer with an SPF in order to keep your skin moisturized while providing sun protection. This will help protect you from sun damage that ultimately leads to premature aging. As a general rule, it is recommended that your day moisturizer have at least 15-20 SPF. If you spend more time outdoors, consider a moisturizer with 30+ SPF.

    What is a Serum?
    Deciding to use a serum can depend on various factors including skin type, age or degree of damage. They are able to effectively absorb onto the skin, delivering active ingredients for maximum benefit. Depending on ingredients, serums contain anti-aging properties that help to firm, tighten, provide anti-oxidants, re-texturize, or address the signs of aging. If you decide to use a serum with your moisturizer, select one with the ingredients or benefits associated with the concerns you wish to address.

    Aging skin may have any combination of wrinkles, sagging or slack skin around the jowls, chin, cheeks and jawline. It may also have evidence of sun damage (photo damage/hyperpigmentation) in the form of spots or leathery texture. The skin may also feel tight and dry. If you tend to have dry skin, you will need moisturizing products that nourish, so you will want to find protective and restorative products. Achieving a moisture balance with the right pH is key.
