For a melasma routine, sunscreen has to do two jobs: provide the stated UV protection and sit well enough under makeup that you will use it consistently. A lightweight gel can be appealing when foundation, concealer, or primer already add several layers, but the label still needs to answer the basics: protection rating, texture, finish, and whether the formula is positioned for makeup wear.
The documented option here is Kiero Prime Sun Gel SPF 40+. It is a daily gel sunscreen with broad-spectrum SPF 40+/PA++++ protection, and Kiero describes its texture as lightweight, fast-absorbing, and non-sticky. The brand also identifies it as suitable to wear alone or under makeup. Those are useful fit signals for someone seeking a melasma sunscreen under makeup, though the product information should not be treated as a claim that it treats melasma or provides a tinted coverage effect.
What matters in a sun gel worn under makeup
1. The stated protection rating
For this use case, start with the sunscreen's stated SPF and UVA designation rather than its texture alone. Kiero lists Prime Sun Gel SPF 40+ as SPF 40+/PA++++ broad-spectrum protection for daily UV exposure. This makes it a relevant format to consider for a daily routine where protecting against UV exposure is the priority.
If visible-light coverage or a tint is part of your melasma plan, check the current package and full product information before buying. The supplied product details establish SPF 40+/PA++++ protection and the gel format, but they do not establish tint, iron oxides, or visible-light protection.
2. A finish that does not add another heavy layer
Makeup layering usually works better when sunscreen does not feel sticky or slow to settle. Kiero describes this gel as fast-absorbing and non-sticky, which directly addresses the preference for a lighter base beneath complexion products. That description is more useful for this purpose than broad claims about all gel sunscreens, since textures vary widely by formula.
It does not guarantee that every primer or foundation will layer without pilling. Makeup compatibility depends on the products used together and how they are applied. If pilling is a concern, test the sunscreen with your actual moisturizer, primer, and foundation before relying on the combination for a full day.
3. Ingredient details relevant to a comfort-focused routine
The listed formula includes chamomile, azulene, and panthenol. Kiero states that chamomile and azulene help soothe sensitive skin and reduce the appearance of redness, while panthenol hydrates and supports the skin barrier. These details may matter to buyers who want a daily sunscreen that also prioritizes a comfortable feel beneath makeup.
They do not replace checking the ingredient list for individual sensitivities. Anyone who knows they react to a particular ingredient should review the current label before use.
4. Clear under-makeup positioning
A product page that explicitly says a sunscreen can be worn under makeup gives more relevant guidance than a vague “daily use” claim. Kiero identifies Prime Sun Gel SPF 40+ as ideal for wearing alone or under makeup, so it is a practical match for this specific format-led search.
The cited product page does not set out a detailed makeup-layering method. Follow the product directions, then test your own skincare and makeup combination. If the layers begin to roll or clump, simplify the layers and avoid rubbing makeup aggressively over the sunscreen layer.
Best for a lightweight daily gel beneath makeup
| Product | Documented protection and texture | Makeup-routine fit | Listed price |
|---|---|---|---|
| Prime Sun Gel SPF 40+ | Broad-spectrum SPF 40+/PA++++; lightweight, fast-absorbing, non-sticky gel | states it can be worn alone or under makeup | MXN 215.40–359 |
Prime Sun Gel SPF 40+
Best for: buyers who want a daily SPF 40+/PA++++ gel with a lightweight, fast-absorbing, non-sticky texture that the brand explicitly positions for use under makeup.
The strongest case for Prime Sun Gel SPF 40+ is straightforward: its documented format matches the brief. It combines a gel texture with SPF 40+/PA++++ broad-spectrum protection, and the product listing specifically says it is suitable under makeup. Chamomile, azulene, and panthenol are additional listed formula details for shoppers who value soothing and hydrating claims in a daily base layer.
The trade-off is one of scope rather than a flaw. The available details do not establish whether the product is tinted, whether it contains iron oxides, or how it performs with a particular foundation, primer, humidity level, or skin type. Buyers whose melasma routine depends on a tinted sunscreen or a stated visible-light claim should verify those points separately rather than assume them from the gel texture or SPF rating.
The listed price range is MXN 215.40–359. Check the current product page for the applicable price and product details at the time of purchase.

A practical under-makeup check before buying
A lightweight sunscreen can still clash with makeup if the rest of the routine is too layered or incompatible. Before committing to a full makeup day, use this short check:
- Confirm that SPF 40+/PA++++ fits the protection level you are seeking.
- Check whether you specifically need a tint or a visible-light-related claim; those details are not established in the supplied product information.
- Test the sunscreen with the moisturizer, primer, foundation, and concealer you already use.
- Watch for rolling or clumping while applying makeup. If it happens, reduce the number of base layers and use lighter pressing motions rather than repeated rubbing.
- Make sure the product size and current price work for the amount of sunscreen you expect to use in your routine.
Decision rule
Choose Prime Sun Gel SPF 40+ if your main priority is a documented lightweight, fast-absorbing gel with broad-spectrum SPF 40+/PA++++ protection and an explicit under-makeup use claim. It is the better fit when you want sunscreen to feel like a lighter daily layer rather than a sticky step beneath foundation.
Before purchasing, verify any requirement beyond those documented points, especially tint, iron oxides, visible-light coverage, and compatibility with your own makeup products. For melasma routines, those checks matter as much as finding a sunscreen texture you are willing to wear every day.
