Glycolic is a strong chemical exfoliant. Due to its nature, using it to alleviate dryness and irritation on your skin can cause more harm than good. If you must exfoliate, as a registered dermatologist, I highly suggest you opt for gentler exfoliants, including lactic acid or AHAs.
Most cleansers come with sulfates to help eliminate dirt and oil on your skin accordingly. Although they can work for other skin types, people with aging skin should avoid them at all costs. Sulfates can cause irritation and dryness, worsening your skin health.
Most skincare and make-up products come with alcohols, including denatured and isopropyl alcohol. The bad news is that alcohols cause extreme dryness and irritation to aging skin. That’s not all, they can worsen skin conditions, including rosacea, psoriasis, and eczema.
