New Retinol Peel

September 13, 2011

Now up on deck: the I Peel featuring a blend of retinol, salicylic acid and lactic acid. This cocktail is appropriate for aging skin showing signs of deeper wrinkles, unwanted pigmentation, roughness and lack of firmness, e.g. almost anyone over 55. This peel desquamates so look for peeling/flaking by day three and continuing for several days. Results are worth it…fresher, healthier-looking skin.

Prep for this peel is important: use of a daily AHA, retinol, or other form of exfoliant. Be sure to discontinue any exfoliant three days prior to the peel to avoid potential irritation.

Post-peel care includes a medical barrier cream, a mild cleanser and most importantly, an SPF of 30 or higher.

Use It Up

August 15, 2011

I am often asked about the shelf-life of skin care products.  There are two answers to this question.  In the case of products with “reactive” ingredients such as retinols, ascorbic acid, alpha hydroxy and beta hydroxy acids, product is old if it has been manufactured more than 8 to 12 months before being used by the client.  This problem occurs because active ingredients undergo auto0oxidation to varying degrees in any formulation.  Stability is defined as maintaining 50% of biologic activity.

The second case involves products with non-reactive ingredients such as hyaluronic acid, minerals and many essential oils.  The general rule of thumb is that unopened containers have a shelf-life of two years while opened product should be discarded after two years.  If in doubt, toss.

Spot Peel Treatment

Certain peeling agents can be used as a spot treatment.  For example, individual blemishes can be treated with 20% salicylic acid to help them heal faster.
