Strict safety standards

Dr.G’s formula has completed skin irritation and sensitive-skin testing, providing gentle, clean care for the skin.

Dr.G Green Mild Up physical sunscreen, SPF 50+. The product text describes it as gentle and non-irritating.

Dr.G GREEN MILD UP SUN+, with physical sunscreen, SPF 50+ and PA++++.

Described as suitable after light-based procedures, easy to remove with facial cleanser, and suitable for layering for added protection.

Physical sunscreen with 0% chemical sunscreen agents. Described as suitable for sensitive skin and gentle. May be used after photoelectric treatments; skin is less likely to look dull after sun exposure. Lightweight, non-sticky, non-occlusive texture that forms a film quickly.

Pure zinc oxide sunscreen with full-spectrum ultraviolet coverage. The traditional sunscreen filters shown are octocrylene, ethylhexyl triazone (Uvinul T150), and avobenzone.

Physical sunscreen reflects ultraviolet rays. Chemical sunscreen absorbs ultraviolet rays, converts them into heat, and releases the heat.

Physical sunscreen forms a protective film on the skin's surface and reflects ultraviolet rays.

Large particles remain on the skin's surface and are less likely to penetrate the skin and cause irritation.

Nanoscale particles are smaller and may penetrate the skin, causing irritation or sensitivity.

Laboratory test.

More than sun protection; it also soothes and repairs.

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

A: Third-party laboratory testing verified that this product contains no alcohol, fragrance, colorants, or preservatives. Apply basic moisturizer before use, such as a moisturizing serum or cream. A richer skincare product may be layered afterward; this dual-moisturizing approach can help ease the skin feel.

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

A: The Little Green Shield sunscreen uses non-nano, large-molecule zinc oxide technology to significantly reduce whitening. For a better result, apply it in sections: dot the sunscreen on areas such as the forehead, cheeks, tip of the nose, and chin, then gently spread it evenly over each area without repeatedly rubbing. Leave it for 1–3 minutes after application; the white cast will naturally fade once it forms a film.
