Thanks to our very generous friends at Sephora, we're giving away a different product every day throughout the month of June. First, a big congratulations to Danigirl77, who won yesterdays's giveaway for Calvin Klein's ck IN2U Fragrances for Him and Her.

No Summer beauty routine is complete without sunscreen, so for this sunshine-themed giveaway, we're offering one of the most serious sunscreens on the market. Shiseido Ultimate Sun Protection Cream SPF 55 PA+++ ($33) is a highly moisturizing face lotion that protects against both UVA and UVB rays. The super-sunscreen is water- and perspiration-resistant, and it covers skin evenly without residue or stickiness. What's more, it contains a retexturizing ingredient that counteracts roughness.

To enter the giveaway, leave a comment in the comments section below by 5 p.m. PDT / 8 p.m. EDT Thursday, June 7, and we'll announce the winner when we post the next giveaway. Please, only ONE comment per person; duplicate comments will be discarded, so commenting more than once won't up your chances of winning. You must be a TeamSugar member to comment, so if you're not a member, please register here for an account. For all of the rules and regulations, click here. Good luck!
