When visiting Tulum, it's important to protect your skin from the strong tropical sun. Here are some sunscreen recommendations: - Choose a broad-spectrum sunscreen with an SPF of at least 30 to protect against both UVA and UVB rays. - Look for a water-resistant formula, as you'll likely be swimming or sweating in the hot and humid climate. - Consider a mineral-based sunscreen with ingredients like zinc oxide or titanium dioxide, which are less likely to irritate sensitive skin.
