Dr.G Little Green Shield sunscreen is a physical sunscreen with zinc oxide as its sunscreen ingredient and is labeled SPF50+. It is described as gentle and non-irritating for sensitive skin, with a fresh texture that is non-sticky, non-stuffy, and quick to form a film; it is also described as suitable for use after photoelectric procedures.

The product is labeled as containing one sunscreen ingredient: zinc oxide, and as SPF50+. The diagram states that zinc oxide sunscreen covers UVB and UVA.

Purely physical sunscreen that reflects ultraviolet rays; high-level sun protection without reapplication.

Non-nano, large molecules are less likely to penetrate the skin.

More than sun protection; also soothes and repairs.

Test comparison: before use and 30 minutes after use.

Washes off easily with facial cleanser; comparison before and after cleansing with facial cleanser.

Zinc oxide works alongside three plant extracts: Centella asiatica extract, Houttuynia cordata extract, and maritime pine bark extract. The product description highlights sun protection and soothing care for sensitive skin after sun exposure.

The formula is labeled 4-free, indicating no added fragrance, mineral oil, colorants, or parabens.

Developed for fragile skin, with a gentle feel. Creamy texture and comfortable skin feel.

Suitable skin types: sensitive skin and fragile skin after cosmetic procedures.

Directions: After skincare, apply an appropriate amount evenly to the areas needed. Two layers are recommended, with extra application to sun-exposed areas such as the bridge of the nose and cheekbones.

Testing: Data from six sensitive-skin tests. After 28 days of use, participants agreed: 100% found it refreshing and non-sticky; 100% found it soothing without redness; 100% found it lightweight; 100% found it unlikely to cause sensitivity; 97% reported improved skin smoothness.

Q: How can you avoid the feeling of skin tightness that may occur after using physical sunscreen?

A: The product has been tested by a third-party laboratory and was found not to reduce skin moisture. If your skin is dry, apply basic moisturizer before use, such as a moisturizing serum or cream. You may then layer on a richer skincare product; this two-step moisturizing approach can help balance the skin feel.

Q: How can you make physical sunscreen look more natural after application?

A: The Little Green Shield sunscreen uses non-nano, large-particle zinc oxide technology to significantly reduce the appearance of a white cast. Apply in sections: use an amount for the forehead, then apply to areas such as the tip of the nose and chin. Gently spread it evenly over each area and avoid repeatedly rubbing. Let it set for 1–3 minutes; the white cast will naturally fade after a film forms.
