Great sunblock, so enjoy the sun!
Size: 6 Fl Oz (Pack of 2)
This sunblock blocks it all and hasn’t any harsh chemicals, meaning it is safe for your baby and for the tenderest of skin. Blocks very well. Easy to use. No harsh scent. I purchased two for our family.

Not greasy at all
Size: 6 Fl Oz (Pack of 2)
This is my first mineral sunscreen. I love that it is not greasy at all. It's easy to apply, and hasn't caused any irritation to my baby's skin.

Fantastic start up
Truskin products are fantastic in my opinion. Not expensive AND effective.. what more can you ask. This 3 pack with Hyaluronic acid, Retinol, and Vitamin C is perfect. I go through the HA faster than the rest so I end up buying the bigger bottle of it. The Vitamin C serum feels incredible on my skin. It feels more moisturizing than the HA. I love using it- just please don’t forget the SPF. This combo pack is perfect for anyone looking to care for their skin. I don’t notice any off putting odors. They all dry down quickly. My skin has not reacted poorly to any of the products. I do stick to my routine of actives(retinol, vit c, tea tree- rotated)to 3x a week and the other days are gentle cleansing, moisturizer and SPF. Since I have switched my skin care routine to TruSkin, I have noticed better looking skin. I’m moisturized with soft youthful looking skin. Recommend and will be buying more.
