Frequently Asked Questions
Clear answers to help you choose your next step.
How do I choose for sensitive skin?
Sensitivity is personal. Start with the step you need, then compare the ingredients, texture and product details with what you already know works for you. A sensitive-skin focus does not mean every formula will suit everyone.
How does this fit into my routine?
You do not need to add every step. Choose what is missing from your routine and follow the directions for the specific product. You can find those in How to Use or on the product packaging.
Are all products fragrance-free?
Formulas vary. Check each product’s ingredient list for fragrance and any ingredients you prefer to avoid. If a detail is missing, ask us before choosing.
Where can I check the size, shade and ingredients?
Check the product title and selected option for the exact size or shade, then open Product Details and Ingredients. Packaging has the latest ingredient list because formulas can change.
What should I know before ordering?
Check the shipping options and total at checkout. Read our shipping information and return policy before ordering, or email support@sensitint.com with a question.
