Keep It Glowing
As we enter our 40s, our skin undergoes significant changes that require a more targeted and effective skincare approach. From collagen decline to hormonal shifts, understanding what’s happening beneath the surface is key to maintaining a healthy, youthful glow.
At FellySaas, we focus on personalised skincare solutions that cater to your unique needs—whether it's anti-aging, hydration, or addressing specific skin concerns. Below, we break down the most common skin changes in your 40s and the best skincare strategies to keep your complexion looking its best.
1. Collagen & Elastin Decline: Loss of Firmness and Plumpness
By your 40s, collagen production slows significantly, leading to loss of elasticity, sagging skin, and deeper wrinkles—especially around the eyes, mouth, and jawline.
How to Combat It:
Peptide & Growth Factor Serums – Peptides help rebuild collagen, while growth factors support skin repair.
Retinoids & Bakuchiol – Retinol stimulates collagen, but for a gentler alternative, try Bakuchiol, which offers similar anti-aging benefits without irritation.

2. Drier, Thinner Skin: Loss of Hydration & Barrier Function
Estrogen levels decline in your 40s, which can result in drier, more fragile skin. The lipid barrier weakens, making skin prone to dehydration, flaking, and increased sensitivity.
How to Combat It:
Hyaluronic Acid & Ceramides – Lock in hydration and strengthen the skin barrier.
Niacinamide & Squalane – Reduce inflammation and keep skin plump.
🛍 Try This: Hyaluronic Hydration Booster - £35🛍 Try This: Moisture Lock Barrier Cream - £45
3. Hyperpigmentation & Uneven Skin Tone
Sun damage accumulated over the years becomes more visible in the form of dark spots, melasma, and post-inflammatory hyperpigmentation.
How to Combat It:
Vitamin C & Kojic Acid – Brighten skin and fade dark spots.
Sunscreen Every Day – Prevent further pigmentation damage with a broad-spectrum SPF.

4. Slower Cell Turnover: Dull & Tired-Looking Skin
Your skin takes longer to renew itself in your 40s, leading to a lack of radiance, dullness, and uneven texture.
How to Combat It:
Exfoliating Acids (AHA/BHA) – Promote skin renewal and boost radiance.
Facial Oils – Nourish and add a youthful glow.

5. Hormonal Breakouts & Skin Sensitivity
Yes, acne can still be a problem in your 40s—thanks to hormonal fluctuations that trigger breakouts, redness, and rosacea flare-ups.
How to Combat It:
Salicylic Acid & Niacinamide – Control oil and calm inflammation.
Probiotic Skincare – Balance the skin microbiome for clearer skin.
