I’m in my 60’s and use the S/A every other night on my T zone where I have open and clogged pores and some congestion. I do dilute it with a little pure Aloe Vera to make it a little less harsh plus this allows me to keep it on my skin longer. Has made a huge difference to all these issues. I us the Glycolic Serum every night which is fabulous for all round skin benefits and certainly dealing with pigmentation spots. Again I prefer to mix it with Aloe Vera so that it isn’t to strong on my slightly sensitive skin. This all works perfectly for me as one of the more mature gals using the brilliant bravura products. Very helpful responses to any queries. All round fantastic service. Thank you.
