It sounds like you're asking about the authenticity of a 20 ml Wishcare product bottle when the company usually offers 30 ml bottles.

To clarify this, the best approach is to directly contact the original Wishcare company or check their official website for product details. Manufacturers sometimes introduce different packaging sizes, but verifying through official sources ensures you get genuine products.

If you are considering using this product for health purposes, I recommend consulting a doctor or a relevant specialist to ensure it is safe and appropriate for your needs.
