Birch Juice Moisturizing Sun Stick SPF50+ PA++++

The Round Lab Birch Juice Moisturizing Sun Stick SPF50+ PA++++ is designed for skin that needs convenient sun protection to reapply during the day without having to go back to the bathroom.

Its balm texture, described by the brand as lightweight and non-sticky, leaves a fresh layer of UV protection without visible white residue.

The formula combines organic UV filters with niacinamide, birch juice (Betula Platyphylla Japonica Juice) and hyaluronic acid to provide hydration in addition to protection. Peptides and vitamin C complete the INCI list.

In a 19 g stick format, it is suitable for normal to dry skin looking for comfortable sun care, to be used alone or over a day cream.

What sets it apart from classic sunscreens is this dual moisturizing and protective role in a stick format, far from the fluid textures that are more difficult to reapply during the day.

How often should I apply the Round Lab Birch Juice Moisturizing Sun Stick?

The brand does not provide detailed directions for use for this stick. For general sun protection, apply in the morning before sun exposure and reapply approximately every two hours outdoors, especially after swimming or sweating, to maintain effective protection throughout the day.

Can I use this stick with vitamin C or retinol?

The stick already contains ascorbic acid (vitamin C) and niacinamide in its formula, so you can use it as the final step in your morning routine without any issues. If you apply retinol in the evening, this is not an issue since this stick is designed for morning use as sun protection.

How long does it take to see a difference in hydration?

The manufacturer does not publish a specific timeframe or clinical test results for this product. The perceived moisturizing effect depends on your skin and the rest of your routine: it is fair to say that no specific timeframe has been communicated by the brand to date.

Is it a mineral or chemical sunscreen?

According to the INCI list, this stick uses organic UV filters (often called chemical filters), such as Ethylhexyl Triazone, Diethylamino Hydroxybenzoyl Hexyl Benzoate, and Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine. It is therefore not a mineral formula based on zinc oxide or titanium dioxide.

Can I buy this Round Lab product in France with complete confidence?

Yes, the stick is shipped from France, with no customs fees, and the product's authenticity is guaranteed. You can also find the entire range in the Round Lab collection to create your complete routine with the same brand.
