What Do You Love About Think?


"Many patients are more cautious these days about the types of ingredients in the products they apply to their skin. When thinking about sun care with physical/mineral blocking ingredients that we know are safe, Think Sun Care is on my short list that I recommend."

"It’s great that ThinkBaby Suncare is paraben, phthalate and PABA-free and a top pick of the Environmental Working Group.This gives me confidence to recommend it, knowing that the ingredients are safe even for my tiniest patients"

Dermatologist Recommended Think Baby & Body Care by Dr. Fieleke

"Think Everyday Face provides mineral protection without the white cast we often see with mineral-based products that sit on the surface of the skin to physically block UV rays. The natural, sheer tint helps even out skin tone, making it an excellent base for makeup or a great standalone face sunscreen for everyday use."

"Even if you’ve been vigilant about sun protection, hours at the beach or the pool can leave your skin feeling parched and irritated. Aloe Vera After Sun is like a drink of water for your skin, quenching it with aloe and providing tingling refreshment with menthol."

"The youngest members of our families often have more sensitive skin or just a plain aversion to having white stuff rubbed all over them. ThinkSport Kids All Sheer Sunscreen Spray SPF50 makes safe sunscreen application a simpler process that parents and kids will both appreciate!"

"After a long run, ThinkSport After Sport Lotion provides soothing, cooling relief to my skin"

"Think Body Wash makes me feel clean and refreshed without drying out my skin. I love that I can use it on my bald head and on my body!"
