The La Roche-Posay Anthelios UVAir Serum Sunscreen SPF 50 has emerged as a staple in celebrity skincare routines, specifically noted for its lightweight, serum-like consistency that functions effectively under makeup. According to a recent interview with CNN, actress Naomi Watts identifies this product as a key component of her regimen, particularly praising its ability to provide sun protection without leaving a chalky residue.
Why Lightweight Serum Sunscreens Are Trending
The shift toward serum-based sunscreens reflects a broader movement in the beauty industry away from the heavy, oil-based formulas that characterized SPF products in the early 2000s.

These products typically incorporate skincare-focused ingredients alongside UV filters. The La Roche-Posay Anthelios UVAir, for instance, includes hyaluronic acid, niacinamide, and antioxidants. These ingredients are designed to provide moisture and environmental protection, effectively allowing the sunscreen to double as a hydrating base for makeup application.
Celebrity Endorsements and Skincare Shifts
Naomi Watts’ preference for this specific sunscreen highlights the demand for products that accommodate changing skin needs, particularly during menopause. When skin becomes drier or more sensitive, the ability to layer products without pilling—or the "chalky" effect mentioned by Watts—becomes a priority.
This trend toward multifunctional, "effortless" beauty is mirrored by other public figures. For example, actress Julianne Moore has publicly highlighted her use of the Bioré UV Aqua Rich Daily Hydrating Facial Moisturizer SPF 50. In a Vogue "Beauty Secrets" video, Moore noted that the product serves as her preferred daily sunscreen, specifically citing its ability to layer perfectly under makeup. These endorsements suggest a growing consumer preference for sunscreens that mimic the sensory experience of a high-end face serum rather than a traditional heavy cream.
Key Considerations for Daily SPF Use
The main barriers to daily sunscreen use—texture, white cast, and compatibility with cosmetics—are being addressed by these thinner, faster-absorbing formulas.
