Texture & feel
SENSORYPure Mineral Defense
Zinc Oxide 11.5% + Titanium Dioxide 4.1% deliver immediate broad-spectrum UVA/UVB protection without any chemical filters.
Truly Invisible Finish
The universal tint and silicone-based vehicle erase white cast across all skin tones — a rare feat for a 100% mineral SPF.
Antioxidant Superfood Blend
Blueberry, açaí, green tea, and hibiscus extracts neutralize free radicals from UV exposure and urban pollution.
Oil-Free, Pore-Friendly
Non-comedogenic formula stays put under makeup and works as a smoothing primer, even on combination and oily skin.
Vegan & Reef-Safe
PETA-certified cruelty-free, vegan, and free of oxybenzone and octinoxate — safer for marine life and sensitive users.
Doubles as a Primer
Soft-focus silicone polymers blur pores and grip makeup, so you can skip foundation on no-makeup days.
Safety & compatibility
SAFE100% mineral filters (Zinc Oxide, Titanium Dioxide) are widely considered the safest UV protection during pregnancy. No retinoids, salicylic acid, or hormone-disrupting chemical filters.
Contains Squalane (safe) but also Glyceryl Caprylate, Sorbitan Caprylate, Stearic Acid, and Rosa Canina Oil — potential malassezia feeders. Patch test if you struggle with fungal acne.
Free of oxybenzone and octinoxate, the chemical UV filters banned in Hawaii and Key West for damaging coral reefs.
Compatible with retinol, vitamin C, niacinamide, AHAs and BHAs used in your morning routine — no chemical UV filter conflicts to worry about.
Lavandula Angustifolia Oil and Anthemis Nobilis (chamomile) Oil add fragrance. May irritate very reactive or fragrance-sensitive skin — patch test recommended.
Dermatologist-tested formula won't clog pores. Reviewers consistently note it doesn't sting or migrate into the eyes — a plus for contact-lens wearers.
Ingredient breakdown
INGREDIENTSZinc Oxide 11.5%Proven
The hero filter. A naturally occurring mineral that provides excellent broad-spectrum protection across UVA1, UVA2, and UVB. Sits on top of the skin and is recognized by the FDA as GRASE (Generally Recognized as Safe and Effective).
- Source: FDA-approved as a Category I sunscreen ingredient.
- Source: Considered the gold standard for sensitive, post-procedure, and pregnancy skin.
- Benefit: Begins protecting on contact — no 15-minute wait required.
Titanium Dioxide 4.1%Proven
The second mineral filter, working alongside Zinc Oxide for stronger UVB and short-UVA coverage. Highly stable in sunlight — it does not degrade like many chemical filters.
- Source: A 2016 study showed inorganic sunscreens like Titanium Dioxide work mostly by absorbing UV light, not just reflecting it.
- Benefit: Coated with Aluminum Hydroxide in this formula — protects skin from reactive oxygen species generated under UV.
Antioxidant Superfood Blend ~1%Promising
A carefully chosen mix of botanical extracts: Vaccinium Angustifolium (Blueberry), Euterpe Oleracea (Açaí), Camellia Sinensis (Green Tea), Hibiscus Sabdariffa, and Oenothera Biennis (Evening Primrose).
- Source: Green tea contains EGCG, a polyphenol shown in clinical studies to reduce UV-induced free radical damage.
- Source: Açaí and blueberry are rich in anthocyanins — potent antioxidants that complement UV filters.
Sodium Hyaluronate <1%Proven
The lower-molecular-weight, more skin-penetrating salt form of Hyaluronic Acid. Helps offset any drying effect from the high silicone load and keeps skin comfortable under the filter.
- Source: Holds up to 1,000× its weight in water for surface hydration.
Squalane <1%Proven
A stable, plant-derived emollient that mimics skin's own sebum. Smooths the formula's silicone slip without adding heaviness or pore-clogging risk.
- Source: Comedogenic rating of 1/5 — suitable for most acne-prone skin.
Silicone Soft-Focus Complex ~15-20%Proven
A blend of Cyclopentasiloxane, Dimethicone, Polymethylsilsesquioxane, and Vinyl Dimethicone/Methicone Silsesquioxane Crosspolymer that creates the signature blur effect, mattifies, and grips makeup.
- Benefit: Spherical silicone powders fill pores and fine lines optically — essentially a built-in primer.
- Benefit: Silicones form a breathable, water-resistant film that helps mineral filters distribute evenly.

Where it fits in your routine
ROUTINEAlways the last step of your morning skincare. Wait ~1 minute for moisturizer to absorb before applying. Reapply every 2 hours of direct sun exposure.
How to use
HOW TO USEShake before use
Mineral pigments can settle. Give the tube a gentle shake to redistribute the formula evenly.
Dot onto face
Squeeze a generous half-teaspoon (about 2 finger-lengths) and dot across forehead, cheeks, nose, chin, and neck.
Blend in thin layers
Use fingertips to press and blend in buildable layers. The tint disappears within ~10 minutes as it sets.
Apply 15 minutes before sun exposure
Let the film set fully so it can grip your skin and form an even protective layer.
Reapply every 2 hours
Especially after sweating, swimming, or towel-drying. Use a sunscreen stick or compact powder for easy touch-ups over makeup.
Who is it for?
WHOPerfect for you if:
- You have sensitive, reactive, or rosacea-prone skin and avoid chemical UV filters
- You're pregnant or breastfeeding and want a fully mineral SPF
- You've struggled with white-cast on past mineral sunscreens
- You have combination to oily skin and want a satin-matte finish
- You want a sunscreen that doubles as a makeup primer
- You prefer vegan, cruelty-free, reef-safe formulas
Consider alternatives if:
- You have very dry skin and prefer dewy-finish sunscreens
- You're sensitive to lavender or chamomile fragrance
- You're strictly fungal-acne (malassezia) safe and avoid fatty acid esters
- You need SPF 50+ for high-altitude or beach-day exposure
- You dislike silicone-heavy textures or "slip" finishes
- You need water-resistant sunscreen for swimming
Skin type compatibility
SKIN TYPESSoft-focus silicone powders deliver a true satin-matte finish that controls shine without flat-looking flatness.
Hyaluronic acid and squalane add light hydration, but dry types should layer over a richer moisturizer to avoid emphasizing dry patches.
Balances T-zone shine while blending seamlessly across drier cheek and jaw areas — a true all-rounder for combo skin.
100% mineral and dermatologist-tested, but contains lavender and chamomile oils — patch test first if you're highly fragrance-reactive.
Non-comedogenic, oil-free, with a low overall comedogenic rating. The matte finish is ideal for breakout-prone skin.
Antioxidant blend supports anti-aging, but a satin-matte silicone finish can settle into deeper lines — apply lightly.

Criticized
- Small tube size — 40 ml goes quickly with proper application
- Lavender scent may bother fragrance-sensitive users
- Universal tint isn't perfect for very fair or very deep skin
- Can pill if layered over silicone-rich moisturizers
- Silicone-heavy texture isn't for everyone
- Only SPF 30 — those wanting SPF 50+ need to look elsewhere
- Not water-resistant for swimming or heavy sweating
Budget-friendly alternatives (dupes)
DUPESSame 100% mineral approach with universal tint and similar SPF 30 protection. Slightly more hydrating thanks to ceramides; less of a satin-matte finish.
Affordable mineral SPF with vitamin E. Tint is medium-only (less universal), and finish is closer to natural than satin-matte.
Universal tint and antioxidant additions (vitamin C, niacinamide). Lighter serum-like texture, but less mattifying and shorter wear-time than Block Star.
Slightly higher SPF and excellent for sensitive skin. Fragrance-free (a plus over Block Star's lavender). Tint isn't as universal-friendly.

Frequently asked questions
FAQYes. Block Star uses 100% mineral filters (Zinc Oxide 11.5% + Titanium Dioxide 4.1%), which are widely considered the safest UV protection during pregnancy and breastfeeding. There are no chemical UV filters, retinoids, salicylic acid, or hydroquinone. The only ingredient worth flagging is lavender essential oil, which most OB-GYNs consider safe in topical leave-on sunscreen at this concentration — but if you're cautious, mention it to your doctor.
Mostly, but with caution. The mineral filters and most silicones are fungal-acne safe. However, the formula contains Glyceryl Caprylate, Sorbitan Caprylate, Stearic Acid, and Rosa Canina (rosehip) Fruit Oil — ingredients that can potentially feed malassezia yeast. If you struggle with fungal acne, patch test on a small area for 2 weeks before committing.
Yes, perfectly. Because it's 100% mineral, there are no chemical UV filter conflicts. Apply your vitamin C serum or exfoliating acids in your morning routine, follow with moisturizer, and finish with Block Star. If you use retinol at night, daily SPF use is even more important to protect your photosensitive skin — Block Star is an ideal pairing.
Block Star excels for combination, oily, acne-prone, and sensitive skin thanks to its non-comedogenic, oil-free, satin-matte finish. Dry-skin users may want to layer a richer moisturizer underneath. It's also pregnancy-friendly and rosacea-friendly because of the all-mineral filter system.
Sun protection is immediate — mineral filters work on contact. Cosmetic benefits (blurred pores, even tone, satin finish) appear within 10 minutes of application. Long-term anti-aging and pigmentation prevention benefits build over months of consistent daily use.
Always last in your morning skincare, after moisturizer and before makeup. The order is: cleanser → toner → serum → moisturizer → Block Star SPF → makeup. Wait about 1 minute after moisturizer to avoid pilling, then dot and blend.
No. Bliss markets Block Star as non-comedogenic, and the formula is dermatologist-tested. The overall comedogenic rating sits around 1/5. Most ingredients are low-pore-clogging, with Squalane (rating 1) and Rosa Canina Oil (rating 1) being the most notable. Acne-prone reviewers consistently report no breakouts.
12 months after opening (PAO of 12M). For maximum SPF efficacy, mineral sunscreens should be used within this window — the filters remain stable, but emulsion separation and antioxidant degradation can occur over time. Replace yearly even if there's product left, especially if you've been exposing it to heat.
Verdict: Bliss Block Star Invisible Daily Sunscreen SPF 30 is a standout 100% mineral SPF that genuinely lives up to its "invisible" promise. With 11.5% Zinc Oxide, 4.1% Titanium Dioxide, an antioxidant superfood blend, and a soft-focus silicone matrix, it delivers serious broad-spectrum protection without the white cast that plagues most mineral sunscreens. It's an excellent pick for combination, oily, and acne-prone skin — and a top choice for pregnancy or rosacea-prone users seeking a clean, vegan, reef-safe formula. The small tube size, lavender scent, and SPF 30 (not 50) ceiling are the main trade-offs. For daily city wear and under-makeup use, it's hard to beat at this price point.
Product Overview
Quick product notes are a great way to check if a product is free from commonly avoided ingredients by skincare enthusiasts. These preferences come about for different reasons depending on the ingredient such as personal experiences, sensitivities, health preferences & etc.
Just because a product is not free from a common preference does not mean it's a bad product! You can make a personal decision whether or not you want to use a product that contains these ingredients or not - click the labels of the preference to read more about them.
Quick Product Notes
Ever used a product that promised a certain effect but provided no results? It might not have contained any notable ingredients that could have been responsible for that promised effect. It doesn't matter what the marketing or packaging «promises» it can do, if it doesn't contain anything that can help - then the likelihood of it helping is low.
We help you identify key notable ingredients that have been shown to help with effects such as acne-fighting, brightening, UV-protection, wound healing & anti-aging to help you achieve your skincare goals smarter. Please note that different notable ingredients have varying levels of research behind them, some are extremely well proven yet some have mixed research in their efficacy.
Just because a product doesn't contain any notable ingredients doesn't mean it's bad. And a product with notable ingredients (or even many) doesn't necessarily guarantee the efficacy of the product performing these effects either. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine this.
Be smart and use this as just a starting point for you to make more informed and smarter choices and compare it with reviews to see if the product is right for you
Notable Effects & Ingredients
Why are some products great for some people and horrible for others? Well everyone has different skin types and different reactions to the same ingredients.
We've identified a range of ingredients that are commonly regarded as potentially good or bad for those with Dry, Oily/Acne-Prone or Sensitive skin.
A product that contains good or bad ingredients for your skin type doesn't always flat out make the entire product good or bad for your skin. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine your skins reaction.
One of the best ways to use this section is to troubleshoot products you've had bad experiences with in the past. Check if it contains any of the marked ingredients to point out suspect ingredients to avoid in the future!
Ingredients Related to Skin Types
Ingredient Safety Breakdown refers to the percentage % of ingredients in different risk categories as classified by EWG (Environment Working Group) if they are available. There are almost endless cosmetic ingredients and they are one of the few organisations globally that have assigned ratings to a lot of the more commonly used ingredients which is why we reference them.
EWG is seen by many to be more on the alarmist side in their assignment of health ratings resulting in rating ingredients as riskier than they actually are. We recommend using this a reference point rather than a strict guide of ingredient safety and to always do further research if into ingredients that you may find suspect.
