Although serums are not new to skin care, they have become more prominent as products with higher concentrations of active ingredients have been developed to target specific skin care concerns. As the molecules in a serum are smaller, they are formulated to penetrate more deeply into the skin
The active ingredients in serums include but are not limited to Hyaluronic Acid (to reduce the appearance of fine lines and wrinkles), antioxidants (to slow the aging process of the skin), Vitamin C (to brighten the skin and help reduce the appearance of pigmentation and age spots), Glycolic Acid (an exfoliant), or Retinol and Vitamin A (highly effective in reversing sun damage and signs of aging).
Serums are applied after cleansing and toning and before a moisturizer. Ideally, apply the serum while the skin is still slightly damp after cleansing. As with cleansing and moisturizing it is important to include the neck and décolleté in your skin care regimen. A few drops of a serum, just enough to cover the face, neck and décolleté are all that is needed. This is one place where more is not better. The skin will absorb as much product as it needs and extra will only be wasted.
Although you may see an immediate improvement once you start using the serum, it usually takes about four weeks of consistent use to see visible results. Depending on the serum and the active ingredients, we often suggest to start with once a day, at night, and then increase to twice a day, morning and night, as the skin adjusts to the serum unless otherwise recommended by the manufacturer.
Be careful to see if there is increased sun sensitivity, and as we always recommend, use a sunscreen of SPF 30 or higher after you have applied your serum and moisturizer.
