Unfortunately, Yonka only samples their SPF 25. Both SPF 20 & 50 have no samples available. Many times I create a “sample” by emptying a sample toner bottle then squirting one of the sunscreens inside and labeling the bottle so there is no confusion. I actually empty several bottles in advance and store them so the liquid has plenty of time to dry before I add a product inside.
Taking the place of the discontinued (and much loved by me and many of my clients) Lait Solaire, SFP 20 is comparable in its thinner nature—more like a “lotion” vs. a thicker “cream” consistency.
With this or any sunscreen, Yonka or other brand, sunscreen is meant to keep your skin from burning—not from any and all sun exposure. What this will look like, especially during a cruise on the ocean, is your skin will definitely get tanned. But if you use your sunscreen product frequently and apply it well, you should avoid sunburns throughout your trip.
