Together with Dr. Emi, we'll take a look not only at the difference between SPF 30 and SPF 50, but also at what makes our SPF products special.

• Pleasantly light texture
• No Tears - No Tears
• Water and Sweat Resistance
  
• No white residue
  
• No sticky or greasy residue
  
• UVB and UVA Protection

The postbiotic Bifida Ferment Lysate in this product strengthens the skin's natural protective barrier, while ectoine provides moisture. In addition, vitamin E reduces oxidative damage caused by UV radiation and other environmental factors.

Key takeaway: 

UVB rays are short-wavelength and are the main cause of sunburn.

UVA rays are long-wavelength and penetrate deeper into the skin—they promote skin aging and cellular damage.
