Any dermatologist will remind you that an ingredient-rich sunscreen isn't just an investment in your physical appearance but your overall health; about 90 percent of nonmelanoma skin cancers are associated with ultraviolet (UV) radiation from the sun, according to the Skin Cancer Foundation. That's why it's essential to find and apply the right sunscreen daily. However, it may seem impossible to find one that doesn't irritate your skin or leave a white cast.

When I finally came across Biossance's Squalane + Zinc Sheer Mineral Sunscreen, it almost seemed too good to be true. The one and only Reese Witherspoon felt similarly when she discovered the brand's products at Sephora, explaining to PEOPLE that she loves how Biossance offers such a "light, easy to wear product range" and was "blown away by how effective it all was considering how clean it is." After championing the brand, she became its latest ambassador and even curated a must-shop bundle for Biossance, which includes a shopper-loved sunscreen.

Buy It: Squalane + Zinc Sheer Mineral Sunscreen, from $30,

Customers have coined this broad spectrum SPF 30 sunscreen a "holy grail" essential for a reason, comparing its versatility to a "Mary Poppins"-like product. It protects even the most sensitive skin, deeply hydrates the skin, and leaves a soft, dewy finish. Its leading ingredient, a nontoxic, non-nano zinc oxide, blocks UVA and UVB rays — which contribute to skin damage, cancer, and burns — and is photostable, so it won't quickly break down in the heat. Concurrently, the other active ingredients, squalane and water lily, work together to provide weightless moisture and calm the skin.

This sunscreen is suitable for all skin types and colors, too. One shopper declared, "The search is over: I finally found a mineral sunscreen that does not leave a white cast on my dark skin, is not greasy, and does not break me out," adding that they will "repurchase [it] for life." Another reviewer appreciated that the sunscreen blends in beautifully without making their fair skin look gray. Even better, they said it provides a summer-like glow that looks great under makeup.

Dr. Loretta Ciraldo, a Miami-based board-certified dermatologist and founder of Dr. Loretta skincare, agrees that the ingredients are hydrating, making it a "nice formula to multitask as both a moisturizer and SPF." However, Dr. Loretta suggests only using this sunscreen as a daily facial protectant and moisturizer since it's not sweat- or water-proof. She also noted that users should reapply this (or any sunscreen) every two hours — the standard FDA-approved direction for all SPF products.

For healthier, glowier, and softer skin, consider adding this broad spectrum sunscreen to your daily routine. The Biossance Squalane + Zinc Sheer Mineral Sunscreen is available at the brand's website, starting at $30.
