There are so many benefits to getting a great facial treatment with a qualified aesthetician, but in order to see that clearer, smoother, brighter, firmer, and more even skin, the treatment must be suited to your skin's needs.
Your first step is to choose a spa or clinic that specifies in their menu that there will be a skin analysis and consultation as part of your facial. This is important for two reasons: first, you will get a service that is tailored to your skin's needs while avoiding irritation, allergic reactions, or undesirable outcomes; second, establishments that do include skin analysis are more likely to have active, professional-grade products and equipment in their treatment rooms that can achieve visible results.
While breakouts after facials are unusual when the aesthetician is trained in proper extraction techniques and when care is taken after extractions to use treatments which suppress acne bacteria (blue LED light, high frequency zapper, benzoyl peroxide, and sulfur are all options at your aesthetician's disposal), it's still a good idea to schedule your first facial at least 3-5 days in advance of any special event you have planned, if for no other reason than to avoid stressing about the possibility of a breakout.
Once scheduled, collect all of your medications, supplements, skincare products, and cosmetics. Prepare for a detailed intake form and verbal confirmation of things like allergies (even to substances seemingly unrelated to skincare), autoimmune disorders, cosmetic procedures, seizure disorders, diabetes, hormonal factors, and eye conditions, as well as a discussion of your past experiences with skincare treatments and products. Each piece of the puzzle will give the aesthetician valuable insight into your skin's type and condition--all necessary to select the right products and treatments. Remember that certain medical conditions will rule out certain techniques (i.e., no microcurrent or salicylic acid for pregnant ladies, no waxing after recent treatment with corticosteroids) in ways you may not even think of, so it's important to arm your aesthetician with all the information she needs to ensure a safe treatment.
On the day of your facial, arrive early with all the information in hand. You'll usually be offered tea or flavored water, and it's a good idea to be in a relaxed state of mind going into your facial, since you don't want to forget anything during the consultation. Be open and honest with your aesthetician (even if you fall asleep with makeup on sometimes!) and relax with confidence knowing that your skin will look great!
