Functional cosmetics for skin ages 25 to 40:
Deep hydration and preventive firmness
Does your skin need more than a pretty cream? From the age of 25, our skin begins to progressively lose collagen and hyaluronic acid. Even if the visible signs aren't yet evident, it's the perfect time to act with a functional skincare routine that combines multi-layered hydration, fine line prevention, and skin elasticity reinforcement.
Why is it important to start taking care of your skin after age 25?
Between the ages of 25 and 40, our skin still has a great capacity for regeneration, but it already begins to show the first signs of fatigue, dehydration, or loss of firmness. Starting a routine based on science and functional active ingredients is key to:
- Preventing fine lines before they appear
- Strengthening the skin barrier
- Prolonging skin's youthfulness naturally
- Increasing deep and sustained hydration
The perfect combination: Absolute Hyaluronic 4D Serum + Collagen + Hyaluronic 4D Firming Cream
Two complementary formulas, designed to work synergistically to deliver visible and sustainable results.
STEP 1. Absolute Hyaluronic 4D Serum
Multi-layer hydration, firming, and revitalizing effect.
Formulated with hyaluronic acid with 4 molecular weights, this serum works on all layers of the skin:
- Fills from within
- Improves skin density
- Softens texture and provides elasticity
- Stimulates cell regeneration
✅ Ideal for applying morning and night before your cream. Its light, fast-absorbing texture makes it a daily essential.

STEP 2. Collagen + Hyaluronic 4D Firming Cream
Strengthens elasticity and prevents fine lines
A functional cream that complements the serum's work with a formula rich in:

- Hydrolyzed collagen, which improves firmness and tone
- 4D hyaluronic acid, which maintains active hydration
- Antioxidant extracts, which protect against oxidative stress
It acts as a booster in your daily routine, perfect for use during the day or as a regenerating night treatment.

At Gold Tree Cosmetics, we offer products that combine the best of both worlds, allowing you to customize your routine and achieve your skin care goals effectively and sustainably.
What you do today will be seen tomorrow. This routine is not a fad: it's a skin health strategy that works from within to keep your skin young, balanced, and functional for longer.
