The Retinol Serum - 0.5oz

The Retinol Serum - 0.5oz by Augustinus Bader is a skincare product, filed under Skincare. Active ingredients can be effective and irritating at the same time, which is why the usual advice is to introduce one at a time. Start with a small amount every other day and build up frequency once your skin has settled. 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.
