Skin Care Basics

A plain-language reading list on what dermatologists generally agree on.

This is a small, non-commercial reading list on everyday skin care — the handful of habits and ingredients that have strong evidence behind them. No products are sold here, no brands endorsed, no anti-aging miracles claimed.

Not medical advice. Anything here is general background reading. For persistent skin concerns, allergies, or any condition that worries you, speak with a licensed dermatologist.

The short version

Most dermatologists agree on a surprisingly short list of things that actually matter for skin health over the long term:

Almost everything else is refinement on top of these.

Sun protection — by far the biggest lever

UV exposure is the single largest contributor to visible skin aging and the dominant modifiable risk factor for most skin cancers. Daily broad-spectrum sunscreen — yes, even when overcast, yes, even indoors near windows — does more for long-term skin appearance than any other single product.

"Broad-spectrum" means the product protects against both UVA (penetrates deep, contributes to aging) and UVB (causes sunburn). SPF 30 blocks roughly 97% of UVB; SPF 50 blocks about 98%. The difference is small, but real protection depends much more on whether you actually apply enough and reapply through the day.

Ingredients with the strongest evidence

Ingredients with weak or no evidence

Many trendy ingredients are marketed far ahead of their evidence. This does not always mean they are harmful — but it does mean claims should be read carefully. "Boosts collagen," "reverses aging," and "DNA repair" are marketing language, not measured outcomes in independent trials.

Simplicity beats complexity

Long, complicated routines rarely outperform short ones, and often cause irritation that undoes whatever benefit was hoped for. A short, consistent routine — cleanser, moisturizer, sunscreen during the day; cleanser, optional active, moisturizer at night — is what most dermatologists actually recommend for most people.

When to see a dermatologist

Persistent acne, suspicious moles or skin changes, severe dryness or eczema, or any concern that affects daily life is worth a professional visit. Telehealth dermatology has become widely available and is often quicker and cheaper than in-person care for routine questions.
