Frequently Asked Questions

Q.I realised your product contains AHA ingredient. I've heard before that AHA is detrimental to skin.
Can you please explain?

A. While we cannot explain what other people claim, we can explain how TNS uses Alpha Hydroxy Acids. TNS USeS AHA in concentrations of 1-2% so as to provide a gentle peel over time, rather than an aggressive action within a short period. Concentrations of less than 4%, especially within a moisturising formula, are proven to be effective and gentle - even on sensitive skins. At this time, we have not combined AHA and sunscreen, because sunscreen is not  stable at the pH required to make the AHA effective. What you may have heard about is how skincare practitioners use AHA's, and the concentrations determine who can use it. For example, cosmetologists can be registered to use AHA products with a concentration of 20% to 30%, and these peels give results similar to microdermabrasion -erasing fine lines/giving the skin a smoother appearance with 1 to 3 applications and then need to be repeated every 3 to 6 months to maintain this skin appearance. Doctors can use AHA products with a concentration of 50% to 70%. These treatments also erase fine wrinkles and remove surface scars, but the effects last longer - up to 2 to 5 years. As always, we recommend you consult your doctor if you have concerns with any products you are considering using.
