    Favorite Sunblock for Toddlers –Clean, Easy, and Effective
    Size: 1 Fl Oz (Pack of 1), Set name: Spray - 5 fl oz., Size: 1 Fl Oz (Pack of 1), Set name: Spray - 5 fl oz.
    This is my favorite sunblock for kiddos! The ingredients are very clean, and it provides excellent coverage. It’s super easy to apply to wiggly toddlers, and the easy-lock top lets me do it with just one hand. I highly, highly recommend this to parents of toddlers and young kids, it makes sun protection so much easier.

    Easy application
    Size: 0.5 Ounce (Pack of 1), Set name: Stick - 0.5 oz.
    The stick’s shape makes it easy to apply on kids’ faces and provides solid sun protection. Like most zinc-based sunscreens, it leaves a noticeable white cast on the skin, which becomes less visible when rubbed in but doesn’t fully disappear.

    My Go-To Brow Pencil!
    Color: Deep Brown, Size: 0.006 Ounce (Pack of 1), Color: Deep Brown, Size: 0.006 Ounce (Pack of 1)
    I've purchased the e.l.f. Instant Lift Brow Pencil twice already, and I'll definitely be buying it again. As you can see in my photo, I used it all the way down to the last bit! The shade is a perfect match for my brows and gives them a very natural, filled-in look without appearing harsh or overly drawn. The built-in spoolie is a huge plus—it helps blend the product beautifully and keeps my brows looking soft and natural. For the price, the quality is amazing. It's easy to apply, lasts well throughout the day, and has become a staple in my makeup routine. Highly recommend!

    Goes on smooth and great color
    Color: Deep Brown, Size: 0.006 Ounce (Pack of 1)
    Long lasting buildable color and glides on smoothly. Comparable quality and color payout to other more expensive brands. If you're not sure what color you are, the taupe is a good choice. The harder you press, the deeper the color. Great product for the price!
