Return & Refund Policy

We want you to love your YinShun experience. If something isn't right, we'll make it right.

Our quality promise

We stand behind every product we make. Our enzyme activity is validated to retain ≥80% potency after accelerated stability testing (40°C / 3 months), and every pad is designed to work like the first one — until the very last. If you feel a product didn't perform as promised, we want to hear about it.

Returns

You may request a return within 30 days of delivery.
Items should be unused or lightly used, in their original packaging where possible.
To start a return, email us at support@yinshunlab.com with your order number and reason for return. We'll guide you through the next steps.

Refunds

Once we receive and inspect your return, we'll process your refund to the original payment method within 5–7 business days.
The refund amount will include the product price. Original shipping fees are non-refundable unless the return is due to our error (wrong item, damaged item, etc.).
You'll receive an email confirmation when your refund is issued.

Skin sensitivity

Skincare is personal, and even the gentlest formulas can be unsuitable for a rare few. If you experience irritation:

Stop use immediately and rinse with cool water.
Let your skin recover before trying anything new.
Contact us — we'll listen first, offer calming guidance, and work out a fair solution (including refunds for opened product in genuine sensitivity cases).

We also recommend a patch test before first use, especially if you have sensitive skin, rosacea, or a history of barrier concerns.

Damaged or incorrect items

If your order arrives damaged or contains the wrong item, contact us within 7 days of delivery with photos — we'll replace or refund at no cost to you.
