Need to Know

Frequently Asked Questions

Everything you need to know before choosing, using, and caring for your skin with Purity products.

Explore Help Center
Is SilkSHIELD a mineral sunscreen?

Yes, it's an all-mineral sunscreen using zinc oxide to provide broad-spectrum UVA and UVB protection. It's formulated to blend in sheer with a lightweight feel rather than leaving a heavy white cast.

How and when do I apply it?

Apply it generously about 15 minutes before sun exposure, either alone or under makeup. Because it's mineral, it protects as soon as it's applied and blended in.

How often should I reapply?

Reapply at least every two hours, and always after 40 minutes of swimming or sweating and immediately after towel drying, to maintain continuous protection.

Does it protect against more than just UV rays?

Yes. Beyond UVA and UVB, it's designed to help defend skin against infrared rays, pollution, and blue light, offering broader environmental protection.

What is TriHex Technology and why is it in a sunscreen?

TriHex Technology is Alastin's signature blend that supports the skin's natural renewal processes. Including it, along with soothing ectoin, means your sunscreen step also offers skin-supporting benefits.

Can I use it on my child?

It's a gentle mineral formula suitable for many skin types, but for children under 6 months of age you should ask a doctor before applying any sunscreen.
