Skincare ingredients: retinoids and sunscreen basics

Retinoids are not one-size-fits-all

Retinoids, including retinol, are vitamin A-related ingredients. Some products can help with mild acne, uneven pigmentation, or fine lines. The formulation and strength matter, and stronger products are not automatically a better choice.

Irritation is a common concern. In darker skin tones, irritation can contribute to dark marks. A clinician can help you choose an appropriate product and discuss gradual introduction and moisturizing. Do not use retinoids during pregnancy; ask your clinician about alternatives.

Read the sunscreen label

The American Academy of Dermatology recommends a broad-spectrum, water-resistant sunscreen with SPF 30 or higher. Broad-spectrum protection covers both UVA and UVB rays. Sunscreen does not block all ultraviolet exposure, so combine it with shade and sun-protective clothing.

Reapply sunscreen at least every two hours outdoors and follow the label after swimming, sweating, or towel drying. Water-resistant products have a labeled protection period of 40 or 80 minutes; they are not waterproof.

Ask before changing your routine

Bring the ingredient lists from your current products to a visit, especially if your skin is sensitive or you already use prescription treatment. Results vary, and persistent acne, discoloration, or irritation may need individualized assessment.
