FAQ - About O4S products

Q1: What are the key ingredients in O4 Skincare products?

A: O4 Skincare products are formulated with a variety of effective ingredients, including activated stabilized oxygen, nano-colloidal silver, nano-colloidal zinc, a range of vitamins, and plant-derived minerals. Specific ingredients vary by product, so please refer to each product's individual listing for a full breakdown.

Q2: What are the benefits of using O4 Skincare products?

A: O4 Skincare products are designed to improve skin elasticity, texture, and hydration. They also aim to lift sagging skin, reduce age spots and discoloration, and promote firmness and radiance. Regular use can lead to brighter, smoother, healthier-looking skin.

Q3: How does the oxygen in O4 Skincare products work?

A: Oxygen is essential for the healthy functioning of skin cells. As we age, our skin cells lose their ability to absorb oxygen efficiently, leading to dull, lifeless skin. The activated stabilized oxygen in O4 Skincare products delivers molecular oxygen to the skin, reversing signs of aging, healing, and repairing damaged skin cells. This process promotes natural collagen production, improving your skin's texture and overall appearance.

Q4: How do I use the O4 Skincare routine?

A: Start with the O4S Oxy-Hydrate Rejuvenating Spray. Spray a light mist on your face and neck as needed to refresh and hydrate the skin. This is followed by the O4S Face, Eye & Neck Firming Crème, applied gently on the forehead and other areas of the face and neck until completely absorbed. Finish with the O4S Moisturizing Face & Neck Crème, applying it gently with the fingertips once a day or as needed. For special occasions or instant improvement, consider using the O4S Instant Eye Lifting & Firming Gel.

Q5: Are O4 Skincare products suitable for all skin types?

A: O4 Skincare products are designed to be gentle on the skin and are typically suitable for all skin types. However, we recommend conducting a patch test before full application if you have sensitive skin or are prone to allergies.


Q6: Can I use O4 Skincare products alongside my other skincare products?

A: O4 Skincare products are designed to be compatible with other skincare products. However, it's always wise to introduce new products into your routine gradually and to monitor your skin's response. If you have specific concerns or a complex skincare routine, you may wish to consult with a dermatologist.

Q7: How often should I use O4 Skincare products?

A: The recommended usage varies by product. For the O4S Oxy-Hydrate Rejuvenating Spray, you can use it as needed throughout the day. For the O4S Face, Eye & Neck Firming Crème and the O4S Moisturizing Face & Neck Crème, you should use them once a day or as needed. The O4S Instant Eye Lifting & Firming Gel can be used for special occasions or whenever you want an instant lift.

Q8: Where are O4 Skincare products made?

A: O4 Skincare line is formulated and produced in the United States, ensuring top-notch quality and adherence to industry standards. Our skincare line is crafted in an FDA-registered facility, ensuring product safety and compliance with stringent regulations for your peace of mind.

A: Yes, O4 Skincare products are formulated to be effective for all genders. Regardless of gender, our products can benefit anyone looking to improve the health and appearance of their skin.


Q10: How long will it take to see results from using O4 Skincare products?

A: Results can vary depending on individual skin types and conditions. However, some users may start to see improvements in their skin's appearance and feel within a few weeks of consistent use. For best results, we recommend using O4 Skincare products as part of your daily skincare routine.

Q11: What if I have an adverse reaction to an O4 Skincare product?

A: If you experience any discomfort or adverse reaction after using any O4 Skincare product, stop use immediately and consult a healthcare provider or dermatologist. It's always a good idea to test a new product on a small patch of skin before applying it to larger areas.


Q12: Can O4 Skincare products help with acne?

A: The active ingredients in O4 Skincare products, such as oxygen and nano-colloidal silver, have properties that can help clear skin and reduce inflammation. However, O4 Skincare products are not specifically designed to treat acne. If you have acne-prone skin or severe acne, we recommend consulting with a dermatologist before starting any new skincare regimen.
