5% Lactic Acid Treatment + Hylasin

What you are looking at is 5% Lactic Acid Treatment + Hylasin by Cosmedica, a skincare product. Active ingredients can be effective and irritating at the same time, which is why the usual advice is to introduce one at a time. Patch test on the inner arm or along the jaw first, especially if you are already using retinoids, acids or vitamin C. Discounted listings come and go, and rarely at the same shop twice. Check the period-after-opening symbol on the pack; once opened, a formula is on a shorter clock than the printed expiry. Whoever is cheapest today may not be tomorrow, so it is worth looking again before settling on the best deal.
