Hi! I live in Houston Texas, so I know all about heat and humidity. I sugguest that you try DHC White Sunscreen SPF25 (
www.dhccare.com). It has no chemical sunscreens and is a light easily absorbed lotion that doesn't look shiney.
Here's what they say about it:
Power of prevention. Nothing is as urgent as protecting your skin from the cumulative damage caused by the sun and its two types of UV rays: age-inducing UVA rays and UVB rays that tan and burn. DHC White Sunscreen is a broad-spectrum SPF 25 facial sunscreen that provides moderate sun protection from both UVA and UVB rays with powerful, chemical-free physical blockers—a safe, effective alternative to synthetic chemicals. Other megastar ingredients in White Sunscreen include alpha-arbutin, one of the strongest nonprescription brighteners available, and antioxidant vitamin C to up the radiance quotient. You’ll also get the benefit of olive leaf extract, aloe leaf extract, and vitamin E. Not only does this valuable sunscreen protect you from future damage, it also offers increased vibrancy as it lavishes your skin with anti-aging luminaries and moisturizers. Formulated with virgin olive oil. Gentle enough for even sensitive and acne-prone skin.
