5. No7 Protect & Perfect Intense Advanced Serum

GH Seal star No7 was the best bargain in the GH Beauty Lab’s face serum test, delivering results on par with or better than pricier options. The peptide, hyaluronic acid and retinol formula earned the best marks for smoothing skin’s texture, plus received strong scores for improving firmness and diminishing pores. Described as “lightweight” by many testers, the serum made skin “look younger” and wrinkles “less visible,” though some reported slight irritation.

6. Olay Regenerist Micro-Sculpting Cream

The GH Beauty Lab’s gold-standard moisturizer, Good Housekeeping Seal star Olay Regenerist Micro-Sculpting Cream delivers great value and near-record levels of hydration with a mix of hyaluronic acid, niacinamide and peptides. In Beauty Lab moisturizing tests using the Corneometer device, the formula boosted skin’s hydration by 68% three hours post-application — one of the highest moisturization scores in Lab history — and maintained the top spot after 24 hours.
