Hi dear, Summer is harder on the barrier than most people realize. UV exposure, air conditioning, chlorine, salt water, and the instinct to cleanse more when the skin feels oily — all of it chips away at the lipid matrix that holds the barrier together. By mid-July, the skin that looked its best in May is often reacting to products it used to tolerate, flushing more easily, and feeling tight an hour after moisturizing. This is not a coincidence. It is a season that strips the barrier slowly, and most routines are not built to compensate for it. Aida's protocol below is. |
