Strengths and forms

Concentrations

U.S. sunscreen products may use titanium dioxide up to 25%. The filter percentage is not the product’s SPF or a guarantee of broad-spectrum protection.

25%

U.S. sunscreen ceiling

A permitted maximum, not a target dose or proof that the product provides adequate UVA protection.

Choosing a strength: Choose the finished sunscreen by its tested broad-spectrum and SPF labeling, texture and ability to apply enough.

Higher strengths: A higher filter percentage does not reliably predict stronger protection or better tolerance.

Formula matters: Particle properties, dispersion and other filters affect the finished product. Titanium dioxide in makeup or a moisturizer is not automatically a sunscreen.

Zinc oxide sunscreen and thick barrier ointment have different jobs. U.S. sunscreen concentrations can be up to 25%; some skin-protectant ointments use more than 25% through 40%.

25%

25–40%

U.S. sunscreen ceiling

The permitted upper concentration is not an SPF rating. Choose a finished sunscreen by its tested protection.

Higher skin-protectant ointments

The monograph specifies more than 25% through 40% in ointments. These barrier products are not automatically sunscreens.

Choosing a strength: For sun protection, choose a tested broad-spectrum sunscreen with appropriate SPF. For a barrier ointment, choose its labeled protective purpose.

Higher strengths: More zinc oxide alone does not prove higher SPF, better UVA coverage or a better diaper-rash result.

Formula matters: Particle characteristics, dispersion and the full formula affect protection and feel. An unlabeled zinc paste should not be substituted for sunscreen.

Common reactions

Can leave a white cast; avoid inhaling powder or spray products.

May leave a white cast or feel heavy; other formula ingredients can irritate.

When to stop

Stop for persistent burning, swelling, blistering or a new rash. Seek urgent care for breathing difficulty or a severe allergic reaction.

How it works

In the skin

On the skin. The finished product delivers titanium dioxide in a particular vehicle.

Entering skin. Formula-unit mass is not particle size. These mineral particles act in the surface sunscreen film; the 500 Da guideline does not predict particle penetration.

Conversion. No activation step is established as necessary for its intended topical role.

Skin response. Particles absorb and scatter UV in the surface film; particle coating, size and the filter blend affect performance.

Additional effects. Proposed pathways do not establish a measured depth of delivery or clinical benefit beyond the studies cited.

Conversion. No activation step is established as necessary for its intended topical role.

Skin response. Particles absorb and scatter UV at or near the surface; barrier pastes also shield skin from moisture and friction.

Product examples

Titanium Dioxide
  • Peter Thomas Roth Max Mineral Tinted Sunscreen — A tinted mineral sunscreen in one universal shade. It works on light-to-medium skin and fails the deep-skin buyers it claims to serve.
  • Revision Skincare Intellishade Original — A tinted moisturizer with SPF 45 at a dermatology-office price. One universal shade, which is the catch.
  • La Roche-Posay Anthelios Mineral Ultra-Light Face Sunscreen — La Roche-Posay's fully mineral face sunscreen — titanium dioxide and zinc oxide, no chemical filters, in a fluid that absorbs unusually well.
Zinc Oxide
  • ROUND LAB Birch Juice Sun Cushion — A zinc oxide sunscreen in a cushion compact, made for reapplying over makeup. Unlike much of the K-beauty sun market, this one is sold here by the brand itself.
  • Vanicream Facial Moisturizer SPF 30 — Fragrance-free mineral sunscreen — 19.5% zinc oxide, five ceramides. Cheap, boring, built for reactive skin.
  • EltaMD UV Clear Tinted — The same formula as EltaMD UV Clear, with iron oxides added for a sheer tint. The tint cancels the white cast — up to a point.

Common questions

Titanium Dioxide:What should I choose titanium dioxide for?

Choose a comfortable tested broad-spectrum sunscreen; check its UVA coverage.

Titanium Dioxide:How strong is the evidence?

Penetration experiments depend on the particles, model and skin condition; the cited study used minipigs. The formula-unit mass is not nanoparticle size and does not predict entry through skin.

Zinc Oxide:What should I choose zinc oxide for?

Choose a broad-spectrum sunscreen you will use consistently, or a labelled barrier paste for wetness.

Zinc Oxide:How strong is the evidence?

Sun protection is established for tested sunscreen products, not loose zinc powder. Formula-unit mass is not particle size. A sunscreen ageing trial cannot isolate zinc oxide or prove reversal of existing wrinkles.
