Why do products that worked in my 40s suddenly irritate my skin now?
As skin thins and the lipid barrier weakens, it becomes more reactive and takes longer to recover from stress. Cleansers that once felt fine can now strip too much oil. Retinoids that once tightened skin can now cause persistent flaking. The skin’s threshold for irritation drops while its recovery speed slows. This is not a sign that your skin is broken – it is a signal to simplify, go gentler, and choose formulas designed for this stage of life. Fragrance is often the first thing to cut.
