Why is the skin on the hands better and whiter than facial skin?
Generally, the reason why hand skin tends to be healthier and fairer than facial skin may be related to differences in stratum corneum thickness, degree of UV exposure, contact with chemicals and pollutants, frequency of cleansing and moisturizing, and sebum secretion. Medical aesthetic treatments such as glycolic acid peels, hyaluronic acid injections (water light shots), intense pulsed light (IPL) therapy, and picosecond laser can be used for skin whitening. It is recommended to visit a reputable hospital and choose appropriate treatments under the guidance of a physician.
Analysis of Why Hand Skin Is Better and Fairer Than Facial Skin:
| Factor | Difference in Stratum Corneum Thickness | Difference in UV Exposure | Difference in Contact with Chemicals and Pollutants | Difference in Cleansing and Moisturizing Frequency | Difference in Sebum Secretion |
| Explanation | The stratum corneum on hands is relatively thicker than on the face, providing better protection against external harmful substances and excessive moisture loss. | The face typically faces sunlight directly, whereas hands are usually at the sides of the body and receive less direct sun exposure. | Facial skin is more exposed to airborne pollutants such as dust, vehicle exhaust, and industrial emissions. | Frequent daily facial cleansing may compromise the skin’s barrier function, leading to dryness and sensitivity. | Hands have fewer sebaceous glands, reducing the likelihood of clogged pores and acne development. |
| Treatment Options for Face | Glycolic Acid Peel | Water Light Injection | Glycolic Acid Peel | IPL Therapy | Picosecond Laser |
| Associated Symptoms | Skin redness, itching | Peeling | Clogged pores causing inflammatory reactions | Dryness, flaking | Acne breakouts |
Analysis of Facial Skin Whitening Procedures:
Procedure Name |
Glycolic Acid Peel |
Water Light Injection |
IPL Therapy |
Picosecond Laser |
Principle |
High-concentration glycolic acid exfoliates the stratum corneum, accelerates skin cell turnover, and enhances melanin metabolism. |
Injects hyaluronic acid and other components to even skin tone, hydrate, and brighten skin. |
Uses broad-spectrum pulsed light to target and destroy melanin particles, promoting skin renewal. |
Emits ultra-short pulses of laser to shatter pigment particles into tiny fragments that the body can easily metabolize and absorb. |

After undergoing skin whitening treatments, proper facial care is essential. Sun protection and hydration should be prioritized, and consumption of spicy or irritating foods such as Sichuan pepper, chili peppers, and garlic should be avoided to support optimal recovery.
