Glycolic acid, sun exposure, and which two other results contribute to fading?

• A. Chemical peels and lasers
• B. Moisturizers and toners
• C. Sunscreen and SPF
• D. Vitamin C and retinol

Answer: (A)

Fading pigmented spots happens most effectively when you actively remove or disrupt the pigmented cells and stimulate faster turnover of skin. Glycolic acid helps with this by exfoliating the surface and promoting shedding of pigmented cells, while sun exposure worsens pigmentation by signaling the skin to produce more melanin.

The two treatments that most directly accelerate fading are chemical peels and lasers. Chemical peels work by applying a solution that deeply exfoliates and removes damaged outer layers, bringing fresher skin to the surface and reducing visible pigment. Lasers deliver targeted energy that breaks up melanin or removes pigment-containing layers and then stimulates new skin growth, leading to faster and more noticeable fading of spots.

Other options don’t fade existing pigmentation as directly. Moisturizers and toners don’t change pigment levels; sunscreen helps prevent future darkening but doesn’t reduce existing spots; while vitamin C and retinol can aid fading over time, the combination of chemical peels or lasers provides a more immediate and pronounced reduction through actual pigment removal or redistribution.
