The commercial look is usually created by reducing the contrast of direct sun rather than simply shooting in harsh midday light.

Best options:

• Diffuse the sun: Put a large translucent scrim/silk above the subject to soften direct sunlight.
• Fill the shadows: Use a large white reflector, nearby bright surfaces, or flash for stills to bounce light back into the face.
• Shoot earlier: Early morning light is naturally softer and less intense. Longish shadows in the ad suggest it may have been shot around that time rather than at noon.
• Use the environment: On a beach, white sand and the sea can act as big natural reflectors, which helps soften shadows.
• Clouds help: Thin cloud cover can act like a giant diffuser.

For a similar look, avoid overhead midday sun when possible, or create your own soft light with a scrim plus reflector. If you want a wide aperture in bright sun, an ND filter can help reduce exposure while keeping shallow depth of field.
