Rebuilding after over-exfoliation.
Redness, tightness, stinging, and shine. Four signals the barrier is asking for a two-week reset.

Over-exfoliation is the most common cause of a barrier crisis in a modern routine. Acids twice a week become acids every night. A scrub joins the party. A retinoid layered on top. Within three weeks the skin is red, shiny in a bad way, and sensitive to plain water.
The reset is boring and works. Remove every exfoliant for two weeks. Cleanse with an amino acid wash at pH 5.4. Layer Skin Repair Serum morning and night. Seal with a ceramide cream. SPF at 30 mineral. On day fifteen, the acids come back in at a fraction of the frequency, once a week only.
