About Our Mandelic Acid Range:

Ishtar Skinlights is the company that bought Mandelic Acid to the UK. We formulated our mandelic acid products to trigger optimum skin renewal response using natural, organic ingredients.

Extra Info:

Long term use of mandelic acid, an Alpha Hydroxy Acid found in the bitter almond,  stimulates deep level skin renewal. It can fade unsightly marks and refine skin texture.   Mandelic acid has proven anti-ageing and antibiotic properties making it an excellent choice for adult acne sufferers. Unlike Glycolic Acid, Mandelic Acid is considered safe for use on darker skin as it carries low risk of causing pigmentation issues. Interestingly, Mandelic Acid is actually a stronger acid than Glycolic Acid (as measured by what is known as the PKa Value). However due to its molecular structure Mandelic Acid causes less irritation, as well as providing other unique skin benefits. This makes it one of the most exciting AHA's available for use in skincare (it has been compared to Retin-A  in this respect).

  By applying this leave on treatment regulalrly, a couple of times  a week, it is possible achieves better, more effective results than with a one off strong peel.

Apply once or twice a week after cleansing at night. Applying a moisturiser *before* applying the serum will slow down the delivery of the acid. This can be a helpful strategy for more sensitive skin. For people who have not used acid products before, we recommend applying Ultralase 10 (10% Mandelic Acid) before using this stronger 15% treatment. It is recommended to maintain a good mechanical exfoliation routine whilst using this product (e.g by using an exfoliating cloth or brush when cleansing).

After 2 weeks, usage may be increased to every other day as tolerated. Increased usage will not be necessary for all skin types, but for certain types of skin issues this can give fantastic results. This type of usage is especially effective for treating areas of melasma, acne and hyperkeratinization. (Note: avoid applying to open lesions). However, in the event of signs of visible peeling lower the frequency of application back down to once or twice a week.

When treating hyperpigmentation, be sure to protect treated areas from sun exposure, otherwise the hyperpigmentation will simply be reactivated by the UV rays!

Each bottle contains 30ml, enough for 2 months if used 2-3 times weekly.

Skin Type:

All skin types seeking to address dull, congested and acne/blemish prone skin. Melasma. Hyperkeratinization.

As with all AHA treatments, it is advisable to use a good SPF to protect the skin from UV rays. Exfoliation will increase UV penetration.
