Retinol and retinoid buying guide
Retinol, retinal, adapalene and tretinoin: what strengths mean and how 9 products compare on formula and cost.
Skincare research: what it does and what it costs
Label-by-label comparisons of everyday skincare: what an ingredient is meant to do, how to start it, how much you actually get and where skincare ends and treatment begins.
Skincare: the short answer
- Start retinoids gently. The AAD suggests the least-intense formula every other night, built up slowly. Adapalene 0.1% is sold for acne without a prescription, and results can take up to three months.
- Read the percentage carefully. 0.2% retinol and 0.2% retinal are different ingredients, and a “complex” percentage can describe a mixture.
- Choose sunscreen for your day. Use a broad-spectrum SPF 30 or higher you will apply generously, and check the 40- or 80-minute water-resistance label for sweat or swimming.
- Compare cost per use, not the bottle. Size and labeled supply change the real price, so compare per ounce or per month.
- How to choose sunscreenEveryday wear, outdoor activity and sensitive skin, with five products compared on SPF, size and price.
- Fine lines and wrinklesWhere skincare and retinoids fit, and when lines call for a treatment instead.
- Hydrafacial: is it worth it?What the facial includes, how long results last and advertised prices.
- Skincare after a treatmentA general routine is not a prescription for recently treated skin. Follow your clinician’s aftercare.

Skincare questions, answered
How should I start a retinoid?
Choose the least-intense formula and use it every other night, building up slowly as your skin tolerates it. Follow any gentler product-specific instructions, and use sunscreen daily.
What SPF should I use every day?
A broad-spectrum SPF 30 or higher in a texture and price you will use generously. Choose water resistance when sweating or swimming is likely, and reapply.
Is a Hydrafacial worth it?
It can be worthwhile for temporary smoothness and a refreshed look. It is a weaker choice for lasting scar correction or treating a skin condition. Try a basic visit before committing to repeat appointments.
