Myderm Ultra-moisturizing SPF 50 Sport Sunscreen Lotion is a high-volume, lightweight SPF 50 lotion formulated without oxybenzone, octisalate, octinoxate or parabens and designed for active outdoor use.

Whether you manage a sports program, run a beachfront rental, or simply want a cost-effective family-sized sunscreen, this one-gallon (128 oz / 3.79 L) Myderm bottle delivers broad spectrum UVA/UVB coverage in a water-resistant, fast-absorbing formula. The lotion is made to be gentle on skin while meeting Hawaii 104 reef-compliant ingredient guidance, so it’s a practical choice when you need lots of product for frequent reapplication.

How does this sunscreen perform for outdoor activities?

The Myderm sport sunscreen is formulated to stay on during sweat and light water exposure, making it suitable for running, team practices, beach volleyball, and other active pursuits. It spreads smoothly without a greasy residue, so athletes and busy kids can apply quickly and continue moving.

• SPF 50 broad spectrum protection against UVA and UVB rays
• Water- and sweat-resistant for sport and active days
• Fast-absorbing, non-greasy lotion for comfortable wear
• Large 128 oz bulk size reduces frequent repurchasing

Is this sunscreen safe for sensitive skin and for reef areas?

Myderm’s formula avoids oxybenzone, octisalate, octinoxate and parabens—common irritants and ingredients of concern for some marine environments—so it’s designed to be milder on skin and align with Hawaii 104 reef-compliance guidance. People with sensitive skin should still patch-test new sunscreens, but the product is made to be less likely to irritate than formulations containing those excluded ingredients.

• Free from oxybenzone, octisalate, octinoxate and parabens
• Hawaii 104 reef-compliant formulation for responsible ocean use
• Suitable for repeated application on active, outdoor skin

How much coverage does one gallon provide and how should it be used?

A 128 oz bottle supplies a large quantity intended for frequent reapplication by families, teams, or facility guests; exact number of applications varies by amount used per person. Apply generously 15 minutes before sun exposure and reapply at least every two hours, or after towel drying, heavy sweating or prolonged water exposure.

• 128 oz (3.79 L) bulk bottle ideal for multiple users or long seasons
• Apply liberally and reapply every two hours or after heavy water contact
• Dispense into smaller pumps or bottles for day-to-day convenience

What practical benefits do buyers get from purchasing this bulk size?

Buying one gallon reduces packaging waste, lowers cost per ounce, and keeps a steady supply on hand for workplaces, camps, and large families. The lotion’s smooth texture speeds application, and the water-resistant performance reduces how often you need to reapply during active use.

• Cost-effective bulk quantity for teams, rentals, or households
• Less frequent restocking and reduced single-use packaging
• Convenient for refilling smaller containers or sunscreen stations
