How to Treat Years of Sun Damage (What Actually Works) | Dr. Idriss

Summary

Dr. Shereene Idriss explains that visible sun spots may be only the surface sign of pigment and sun damage that has accumulated deeper in the skin. Her main recommendation is to build a consistent, pigment-focused skincare routine and protect the skin from further UV exposure before considering laser treatment.

Key points and strategies

• Tell freckles and sun spots apart:

  • Freckles (ephelides) are often genetic, appear in childhood, and become more noticeable with UV exposure, but may fade when exposure decreases.
  • Sun spots (solar lentigines) tend to appear later, reflect cumulative sun exposure, and generally do not fade and return in the same way freckles do.
  • Both commonly appear on sun-exposed areas such as the face, nose, and cheeks.

• Understand the deeper pigment: Idriss describes melanin as part of the skin’s response to UV exposure. Pigment can accumulate below the visible surface and become more noticeable over time. A Wood’s lamp can make some underlying pigment easier to see, though the video presents it as a viewing tool, not a substitute for professional assessment.

• Make at-home care the first step for pigmentation: She advises trying a consistent skincare routine for 8–10 weeks, with a prescription option if appropriate, and then reassessing before spending money on laser treatment.

• Treat lasers as a possible later step, not the starting point: Lasers can help, but results may not last if underlying pigment is not managed or UV exposure continues. Idriss also cautions that laser-related inflammation may worsen pigmentation for people prone to post-inflammatory hyperpigmentation (PIH). She says melasma needs particular care and does not recommend laser as a first-line treatment for it.

• Consider a combination of pigment-targeting ingredients:

  • Kojic acid: Helps limit pigment production by inhibiting tyrosinase. Idriss identifies about 1% as a useful concentration and cautions that higher concentrations may cause irritation.
  • Tranexamic acid: May help calm inflammation-related pigment pathways. She describes it as a possible adjunct, especially for people prone to melasma or PIH, and says it may pair well with an exfoliating acid such as glycolic acid.
  • 4-butylresorcinol (resorcinol): Also targets pigment production through more than one pathway.
  • Her broader point is to combine compatible actives that work in different ways rather than relying on one ingredient at a high concentration. She also notes that vitamin C and glycolic acid can be part of a routine.

• Wear sunscreen consistently: Idriss emphasizes sunscreen to prevent new UV damage and help maintain results. Treating existing spots without ongoing sun protection may allow pigment to reappear.

• Don’t assume it’s too late: She encourages people of any age to take steps to improve their skin, while setting realistic expectations and focusing on what bothers them.
